How do you charge your e-bike when you're out and about? ⚡️
Electric Mountain Bike Network Well done Steve. A really down to earth pragmatic approach. Great to show a range of options, rather than get deep into the tech like I do 😏 I’ll let you see the Rolls Royce version when I’ve installed my 25.2V, 200 Ah, 80% discharge, low weight, small volume, Lithium NMC chemistry, AC energy buffer bank. Kit arrives this week. My smart ass ways aside your video was great showing there are many ways to skin a cat!
My wife and I traveled for 2 weeks in Alaska and the Yukon Territory last fall with our two Felt eFat Bikes and a home built cargo trailer conversion. We camped in remote locations that were completely off grid. (If you can go to a pub or B&B with power, you aren't really off grid.) We carried a quiet Honda EU 2000 gas powered generator, which we could power up for a couple hours at a campsite after a long ride. We could also use it to recharge our 12V deep cycle battery that we use to power lights and a roof vent fan in the trailer. We also towed the generator in a sled behind a snowmobile on a winter trip into remote, truly off grid cabins in Alaska's White Mountains. I rode the e-Bike and carried my wife's battery as an extra. My wife drove the machine with the camping gear and generator. We could do 50 km days in temperatures between -4º and -15ºC (5º to 15ºF) and just run the generator a few hours with an extension cord running into the wood stove heated cabin. I've also used it to plug-in heaters on my snowmobile or truck and get them started when parked remotely at -40ºC/F
John Schauer The 2kVA Honda is 1600W continuous and the 1kVA is 900W continuous. Lovely little generators.
Just an important note that I just realised hasnt been mentioned here. If you are going the inverter path, you should be using a pure sine wave inverter that can cope with the power demands of your charger. Modified sine wave inverters are "iffy" for electronic gear and some of these chargers are very "electronic" you should therefore only be using a decent Pure Sine Wave inverter if you dont want to risk stuffing your ebike charger. Perhaps its pretty much assumed knowledge these days as these inverters have been around in general use for over 20 years. Just thought I should mention it in case some folk are just learning about inverters. In the " old days" pure sine wave inverters cost up to 10 times the price of a modified sine wave inverter ..... so it was easy to distinguish what you were getting. And all inverters are so cheap now that you can pick up a decent Pure Sine Wave inverter for not even twice the price of a modified.
Anyway lugging around old inverters and mains chargers is a pretty old fashioned and inefficient thing to be doing these days .... especially as DC/DC Boost converters are so cheap and efficient.
my favourites was the car/ van ones, gives you complete independece so you can travel the world and remote places without a worry:)
I've watched this a few times and it always cracks me up. 🤣🤣🤣 Remember! Don't annoy the land lady 👍🏻
Great video. Having created the absolute ultimate Motorhome set up, I would recommend avoiding cheap inverters and go for something like a Victron 500 watt pure sign wave inverter. This won’t knacker your precious chargers / batteries and while they cost about £180, the cheaper versions really aren’t worth the risk. The Victron is a heavy 4kg device, but runs cool and quiet rather than in a hot, noisy and frankly scary way that some of the eBay specials do. It’s also important to monitor battery levels and do the maths to avoid flattening and damaging the leisure batteries. Finally, don’t be tempted to plug a cheap charger into your lighter socket... it risks melting cables. The power draw will be in excess of 200 watts for an inverter and charger, so pushing towards 20 amps... this is a lot!
Heheh I like how you call them 'liesure' batteries.
Over here we have multiple batteries usually on one petrol driven ATV.

"Useful idiots" is what Stalin called you.
A lil heads up. A normal 12v auto battery should not be used for static charging for multiple reasons. 1st they have a very limited number of discharges due to the fact that they are designed to have short use IE, start the car, and then are charged immediately as the car is running. Also the 12v systems of your car are designed to run on 12v plus, most alternators run at 13.4v-13.7v. Your starter, glow-plugs and other systems will suffer from low voltage and your battery will have a greatly decreased life. Most leisure batteries are Deep cycle and are designed to be depleted to a much lower state and at a high number of cycles. That said, the best way to insure long life for any battery is proper regular charges. A leisure battery should have a split charging system either automatic or manual to keep your battery charged at all times while the engine is running. The only time you should need to plug in ,230vac, a leisure battery is if you are parking up for extended periods. Inverters are very sensitive to heat and moisture and 99% of the time should not be located under the bonnet, keep them clean, dry and inside the car. Having a proper inverter system enables you to be self sufficient, you can pack a lunch and run the car for a bit while you warm-up, have a bite and a rest also you can go anywhere. Have fun.
OBC Good to see more depth to the issue. When sizing properly one also needs to take into account battery Ah reduction due to temperature, age and Peukert effect. Ideally if going AGM a 240Ah at the 20 hour rate is about right if adhering to 50% DOD, once inverter and bike charger losses are accounted for too. That’ll give you one and bit full charges of a 500Wh battery whilst sticking to accepted rules for battery care and cycle life longevity for a leisure battery.
Yeah I dont get why folk do the charging a static battery thing. They dont have a long life expectancy when you do this .... even for a deep cycle battery. Kinda why I charge with a DC/DC boost converter and plug in only when driving or use a solar panel when stopped. Bit of a false economy using a static battery really.
barry taylor Indeed. Even if adhering to 50% DOD, accounting for load, Peukert, ageing and temperature it can still be false economy. Mind you with cheap wet lead economy and life cycles is not such a concern. My static leisure bank I’m fitting is 25.2V, 200Ah, NMC Lithium with BMS as I think I said but it’s for other loads in my camper besides bike charging.
Best thing to do is get a spare battery and keep it in a back pack...or in your van
OBC said, "...most alternators run at 13.4v-13.7v."
That's only when the battery is fully charged. Alternators can run a bit higher than that. 13.4-13.7 is barely above the FLOAT charge level of 13.4V on a typical 12V lead-acid flooded auto battery (float levels are slightly different for "SLA" or "AGM" 12V batteries, but even small differences matter here). An alternator typically runs 13.8-14.8V while charging the car battery after it has been used to start the car or has been used in engine-off "accessory" mode for awhile.
There also can be a major voltage spike while a car is being started. The battery helps filter it to some degree but additional protection circuitry is advised on electronic devices that connect directly to a car's "12V" power.
lol the lady in the kitchen wanted to do that since a long time
Just a word on solar panels - I see the campervan in the video has a roof rack going across the panel casting a shadow - on all the panels I've seen so far, any shade at all - even a seemingly small amount - can knock the panels' efficiency WAY down.
I have been looking into ways to set up my van for charging when I get my bike and this vid has given me some good ideas. Thanks for doing this!!
Thanks for putting this up much needed video so we can keep a good name for the e-bike community.
Could you do a segment on buying used e-mtbs focussing on the e-bike-specific components...the benefits and the risks, checks for likely wear and what is excessive wear, how do you know if motor and electrics are performing as they should...cheers
Mallards Pike Cafe - "Yeah, i'll have a bar of boost" - brings a new meaning to the definition
Instead of inverters, I'd suggest dc-dc converters. There's plenty on the market that would suffice for the CV/CC modes for lithium battery packs on ebikes.
Legendary performance from the lady in the pub 🤣🤣🤣💯❣️❣️❣️❣️❣️
We've got her acting on retainer!
The UKs own Doc Brown, legend!
GREAT SCOTT!!
Funny reaction of an english pub when you plugged in,priceless!
I just bought my first mountain bike in about 20 years, I have already started googling e-bikes ;-) I think I should learn to ride it properly first. Anyway great channel, subscribed.
after chargeing the battery i always allow it to cool down in case any heat was built up chargeing and i carry a spare battery for long runns.
Enjoyed the video
Use a Grin Satiator and you don't have to worry about that nonsense.
charging vs chargeing
Great perfomer and value!
The idea about having your engine connected to the battery, it would be good to have a charger on the inside of the car so that it can charge while your driving towards the trails
The ONLY time a battery should be charged from a fossil fuel motor is when the motor is being used for something else also, like moving the car.
Can you charge e bikes in camper van on 12 volt battery
THIS WAS SOOOOOO GOOD
I have a similar campervan with a solar panel. Indeed as the guy said, if we are charging the battery in the van we'd need to deal with the inefficiency of the inverter and the battery charger, one used to bring the power from ~12v to ~220v and the other to drop from ~220v bak to ~12V, which is the voltage of the e-mtb batteries. I'd be curious to see an alternative to charge the e-mtb battery straight out of a leisure battery (used on vans), 12v to 12v. Would that be feasible?
Uf Steve, that woman you messed up the pub !!! I enjoyed it again.
In Australia, the land of plenty of sun... when in the mountains and forest with the ute riding the e-mtbs, a 120w solar panel, 40 ah battery, an inverter and Bob's your uncle!
A good way to go but for full disclosure...will need 10hrs of sunshine to fully charge.
Also, the panel would have to be less than a couple years old and the sunshine would have to be striking the solar panel at a solid 90 degrees. Any off-angle exposure and solar cell aging can rapidly and substantially reduce the conversion efficiency. Also, the more north or south your latitude from the equator also affects panel efficiency.
True - I recently put 3 25 year old 75 watt panels flat on my roof - from 10am till around 2pm I'm getting 10 -12 amps into the 120ah battery depending on temperature and the angle of the car. Certainly does NOT take 10hrs to recharge as Alfred says below and does not have to be a new panel nor 90 degrees. Sure, if it was 90 degrees I can get closer to 14 amps but being flat is nice and unobtrusive and negligible wind resistance.
Car charging through an inverter is very inefficient. Bosch actually has a 12V travel charger which plugs straight in the cigarette lighter. Bosch this year also has a high power fast charger, so you don’t need to take that desert in the pub because the battery isn.t charged yet.
You can easily build the bosch type in car charger. Research DC/DC boost converters. Also fast charging is thought to limit thr battery life .... but I know its useful sometimes. Lol.
When you use 250/500w motors with those cute little petite batteries that may be an option. Also "high power" or fast charging just reduces the number of charge cycles you will get out of the pack.
@UCAxZI7YrugZAdb9QaXQaXDA Generally speaking... with a big pack depleted down to 20% charge you can "pour" a charge into it faster (higher amperage) and not stress the individual cells as long as they aren't charged past 80% (approx.). I can charge and store 15Ah at a higher amp (quicker)... not have depleted the pack past 20%, not charge past 80%, get over 70 miles range, and not stress the packs at all. Not mistreating the batteries can extend the number of charge cycles past 1500. I also recommend using a Grin Satiator to properly charge and maintain the batteries.

Bisch Bosch jolly good
My 5m extension cable has come in very handy.
The charging setup in my box van includes (2) 6 volt deepcycle golf cart batteries in series feeding a very efficient 2000 watt sine wave inverter. I can charge a 48 volt 850 watt-hour battery twice from a spent state of around 17-20% on the house batteries, and once off of the twin chassis batteries. Then I need an outlet to charge the house batteries back up since they are not hooked to the engines alternator (yet).
What capacity are the golf cart batteries? Still running this setup or something different?
The Lady was right on the money, that was good fun. I can plug my charger into my F150 and away we go.
I plan routes mainly around previously investigated friendly cafes and pubs. I always place an order of food and drink...why not ? Off grid campsites where I spread my hammock, usually have generators if needed. I have only once been charged £1 for a bat. charge.
Wait for thunder and get the battery struck by lightning - job done.
This is by far the best advice will definitely do this 😂

Lightning rod on the back.
Thanks guys I've been waiting for this type of video for ages . Now I know what to expect if I got a inverter for my camper .1 charge per 100amp leisure battery , think the way forward for me in the winter is a cheap site . But great in summer or just use a suitcase generator, Great information in this video well done 👍
The E bike Campervan man It’s not really one full charge from 100 Ah for a 500 Wh battery if you work out the inverter and charger losses and are mindful of a 50% discharge on that starter battery.
How about using 200Ah then you WILL actually get a full charge!
I see I big crack in the skid plate of the Levo battery at 7:55 and a bunch of crud in the hole. I wonder if the battery is at risk on bigger hits to this spot?
There must be some setup you can make, towing a small trailer behind you, full of solar pannels and charging a 2nd or 3rd battery. Of course this would be suited more to a road than off road.
There is, I seen a UA-cam video about a year ago of someone that built one. It was made more for camping than just collecting power and I think the trailer had a mattress in so all he had to do was lift up the lid with the solar panels on, get in and sleep or anything you would normally do while in a tent.
So whats the deal with dynamos? I dont know anything about them, but havent really seen them mentioned for charging ebikes. Downsides?
they output 3 watts.. + the energy to power the dynamo is either coming from your legs or from the motor > battery.,, meaning is a useless way of trying to recharge your ebike battery
Can I charge my laptop computer from my ebike battery (360 watts/volts) ? Can a store build the adaptor?
to get max charges out of my bosh battery i was told never charge it to full charge it to 80-90 and don't let it get below 20 percent i was informed that the charge cycle would increase by 300 percent also using 2 batteries on my bike helps the discharge rate as the power draws 5 percent at a time and then transfers to the next battery so there is much less stress on the batteries wits 2 batteries on my bile i have a range of 75-150 miles
You spoke of charging battery packs outside when the packs can't be removed from a bicycle and you happen to be talking about the Alps...so I thought this info might be of some value.
One vital tip missing...unless I missed it in the vid...one should never charge a lithium cell battery pack that is at or below freezing (0C/32F), so charging the pack outside in a forecast near freezing temperature is ill-advised. The pack likely will not receive a full charge and doing so MAY damage one or more cells in the battery pack. Whether there is persistent damage depends on a number of factors even including the charger's "stop-charging" algorithms, so it's best to just avoid the sub-freezing charge.
Additionally, running the bicycle on sub-freezing battery pack will deplete the pack more quickly than if it first is allowed to warm-up to a decently human-comfortable temperature. The lithium cells commonly used in consumer applications are extremely inefficient at cold temperatures while charging or while discharging.
Off grid charging using the pubs electricity supply that comes from.the national grid isn't really off grid charging is it?
At 4:19 😂😂 nice way to wear your hat Steve!!
I need a channel for bike tourist. Specifically, trans-am tours. Besides stopping at local libraries or carrying a solar panel, the only options apparently are paying big bucks to stay at camp sites with electrical hookups.
why can't you charge while driving from car's 12v cigarette lighter socket in the dashboard? with some kind of inverter of course
#GMBN who knew your neighbor was a genius!?
its actually a very inefficient way of doing it.. why go 12v DC > 230v AC 50Hz > 42v DC ( 36v ebike charger )
you should just be going from 12v DC > 42v DC using a suitable charger.. im 99% sure they exist
Sausage Fingers you can get a dc to dc charger for levo, sold by bmw.. hard to get hold of though
A small car battery is 45 Ah * 12 V = 540 Wh. A diesel van battery of 80 Ah * 12 V has capacity of 960 Wh. Current e-bike batteries are 500 Wh and it seems the capacity will grow up to 620 Wh in 2020. Taken the efficiency of the inverter and of the charger I cannot see charging from the car battery as a practical solution unless the engine is on. Fancy 4 hour of idling your engine... A gasoline generator (if one is completely off the grid) seems to be the only solution but let's not talk anything about ecology.
I know Tesla has a charging station map, why not a ebike maps.
There are some in Germany but there’s no standardization between ebikes to be able to so you would just have an open outlet smartphone losers would abuse.
Can anyone tell me what jacket that is the black at 6.40 ? Thanks
There are also off the grid bikes too😅
lol
Yeah I have one of those ..... but the engine is getting a tad slow. Lol
That's a genius idea, they should've included this in the video! ;)
Emtb riders: I wonder how I can charge outside of my home
Embn: go to a church and charge up 😂
This video was informative and funny. Love it.
Those things that stick sideways out of the bottom of your bike can be turned with your feet. You should learn how to do it. It's a useful trick to go faster.
Most ebikes give help on hills, when your on the flat the legs do the work. Not all of us have legs like garth so a bit of a help is good. What is not good is smart alec type idiots.
Sweet I already have the whole set up for off grid, but the bike I want can only charge battery on bike. I am going to investigate that so I can have 1 or 2 batteries charging while I'm riding
Thim I’ll be doing a blog about this in the new year but basically you’ll need at a minimum a 240Ah AGM leisure battery and a 1600VA inverter if two Bosch standard 36V/4A chargers.
But what about mounting a power generator on your ebike to charge while riding it.
7:33 That's a lot of watts for an ebike charger. My North American Rad Power Bikes charger outputs 84W and takes a maximum of 120W from the wall.
A little whacky but very good 👍
NICE WORK MATE
12 vdc to 240 vac then back to 24/36/42 vdc, what an inefficient way of doing it. how about cutting out the losses via the inverter and go 12 vdc to a step up dc-dc converter with CC/CV (constant current / constant voltage settings) set it to the required ebike volts/current job done. no AC power required.
We (I) need an update video on the topic!
This video could be updated now, by adding electric cars with V2L (Vehicle to Load) technology. Cars like the affordable MG4 and more expensive Kia EV6 have this. The new Ford e-transit too.
I’d also like to see the use of portable unfoldable solar panels to charge.
Any other green solutions welcome.
You could buy a leisure battery and a inverter , and charge the battery before you leave home then you wouldn’t have to use your vehicle battery, and although more expensive opt for a pure signwave inverter , they are better , I paid 200quid for a 3000 watt inverter for my van 3yrs ago , to run a tv and some lighting in my van. Cheers Shane uk 🇬🇧
or just buy a 2nd battery and take it with you
A McDonald's is always a place to charge your bike most have sockets in their booths, just get something from there though most employees don't care how long you are there.
Libraries would allow you too just ask before and be polite offer maybe to give something to the library a pound or something.
You will likely need a library card though.
You can chill read some books or surf the web waiting.
Your workplace will definitely allow you too charge up.
What would be cool is if train stations allowed you too charge while also having a carriage which just stores bike's
XLnt !
Interesting video , I really have to look into the charging opportunities when I am on the road since my dog need his daily 7-20 km exercise .Thanks :-)
I bought one of those cheap torches from amazon that you can wind up, wired into my battery, been 16 days so far and my lights just came on......but then they went off again, perhaps I’m not thinking this through. 🤔
Charging from a pub/B&B or other mains supply is not "off grid" if their power is coming from the mains supply.
This is an issue obviously.
Im going down the road of wild charging..got a 4ah charger with croc clips instead of a plug.
Its amazing the places you can find 240 volts.
Lovely! Can you do a review of the big and powerful ebikes like Stealth, HPC Revolution, Cab Eagle and Vector bikes?
Yawn
Very good vid
How is using someone else's electricity off grid? Maybe keep to terms you understand.
The boot charging while driving to the trails insures perfect battery maintenance, the time the battery sits full is kept to a minimum, charging back to 65% storage on the way home could be a bit more tricky depending the state of charge to begin with, a simple timer would not work unless the battery is always discharged to a simular state, I like the leisure battery but it's a lot of weight to put in a small car and fit your bike on top.
A design for life Choose lithium NMC chemistry then. About 8kg for a 12V 100 Ah. High initial capital cost but 4 to 5 times the cycle life of lead and physically much smaller. Also much quicker to charge and has a stable discharge voltage (little or no voltage sag).
@@JohnRushworth
Having a quick look victrons offer gel 150ah batterys for £335 or the lithuim vesrion is close on £1700, that would charge a 48v 22ah batterys with a bit of breathing room for efficiency losses or up to 3 normal ebike fully charged plus invertor costs, pitty the battery could not be charged direct from a 12v source so there's no as conversion just a dc step up then you could get closer to the stated capacity of the leisure batt with less heat and conversion losses.
A design for life Hi. Roughly a standard Bosch Charger via an inverter via the Bosch 36V/4A DC output, AC input charger is 220W from the leisure battery. For inverters it’s usually better to use AGM than Gel for lead chemistries. I blog for Victron and we do LFP and NMC type Lithium chemistries. You can’t compare 20Hr normally quoted Ah rates of lead types such as AGM, Gel, directly with the Ah of Lithiums nor indeed cycle life. A lead acid might be around 500 cycles and Lithiums depending on chemistry 2000 to 3000. Bosch did do a Buck Boost DC to DC but half the standard charger with 36V/2A output ref www.bike-discount.de/en/buy/bosch-charger-12v-dc-dc-travel-charger-451743
Here’s a blog I did about three years ago comparing lead vs lithium. I’ll do a new one next year about ebike charging to build on Steve’s video showing AGM and lithium options with cycle life costs. www.victronenergy.com/blog/2015/03/30/batteries-lithium-ion-vs-agm/
@@JohnRushworth
Hi, I've done a few electric rides in my time and belong to endless sphere forum, I agree completely with lithuim it's ability to hold state of charge is far superior to lead acid aswell as a much better non linear discharge with tons of other facts as you know, I've followed the cell chemistry a bit of varying 18650 and lipos over the years and used most of them to get a stand on 40kg electric scooter to 50mph over 2 years ago but I've found the 18650 to age very well I have a Sanyo pack from 2013 in an a2b metro that's still got over 85% of it's original soc with many a cycle ive lost count and I'm the second owner too.
@@JohnRushworth
I'm sure a standard Bosch charger circuit could be modified to decouple the ac side and its rectification and then feed it's favoured dc input if it varies on it's output then there would have to be a data pin of some kind an arduino could read and vary the power supply of a variable dc dc meanwell psu with its potentiometer removed and piggybacked to the arduinos pot, bit of coding and it will all sing together that's that hard way hopefully they use a simple ac side I'll try get a schematic.

Jokes aside, great vid as always.
A generator helps too. I have all this and a genny in my bus. Just need a spare bike battery now.
Some good points made in this! Like it!
I wonder if there’s a way you can use an adaptor from an electric car charging port to charge the bike
J anstee95 I’ve thought about rigging something up, but they look so complicated
Yes you can. You can if you get the adapter from Amazon for the J type outlet or whatever they use in your country. Then plug your charger into the other end .
Great show Steve 👍👍👍
how about taking a quiet suitcase generator on trips ? We have customers at our trials park with Oset and Mecatecno bikes and that's what they use to recharge the bikes with.
They would do fine and in fact if Honda no need to go for the 2kVA, 1600W continuous output as the 1kVA is enough at 900W continuous power. Mind you on a standard Bosch charger you are still running it for 4.5 hours for a full recharge. About 800 U.K. pounds for the smaller Honda, less if cheaper Chinese makes.
@@JohnRushworth if you can please post up a link or two to a good generator ;)
Michael Joseph This is the one I have www.justgenerators.co.uk/portable-camping-caravan-generators/honda-eu10i-generator.html and this a cheaper option www.justgenerators.co.uk/portable-camping-caravan-generators/hyundai-hy1000si-4-stroke-inverter-generator.html
What a waste. Burn fuel in the nature only to get your supported ride? Ridiculous!
@@TheAtikalz Yes, it's inefficient. Solar would be better.
So with a backpack and an inverter and a collapsible wind/water turbine thrown into a stream/river you could stop on the trails for lunch and throw your turbines in a river and let it do the charging for you while you have a mid day rest.
Someone needs to design a lightweight turbine and integrate it onto the bike frame and of course a small inverter and that would allow people to go out for a few days if they want without needing to carry 3-4 spare batteries.
Multiple batteries isn't a solution you need to take advantage of the environment around you, most mountain ranges don't suffer from lack of wind or water that's clean energy going to waste.
Turbines can be made super light from either stainless steel or carbon fibre.
It's an easy problem to resolve as long as you have wind or flowing water.
There's far more rivers and water in Wales so it's a bit of a no brainer for us here.
That women in the pub should be an actor
the Fonze got into E-Bikes!
Seems daft no one supplies a 12v DC charger for ebike batteries, would reduce the amount of loss through inverter and charger loss
remember, ALWAYS say you will come back every day! even if you have no plans to!
Scooter batteries are less expensive than ebike batteries. Can scooter batteries be used to power ebikes? 😊
sure, but the range would be quite "unimpressive" so you would need so many of them, that the price is really no concern ;)
What about the old Generators that flipped to touch the tyre, anyone tried this?
so where are they?
perfect, I live in the Alps ;-D
Some bikes charge while you pedal?
that is a weird set up, grab one that plugs into the cig lighter port and make sure the inverter can charge lithium batteries ..now your battery is safe in the car out of the elements and on a safe inverter . good tip.
Something to know about car batteries: they're designed for large surges to start the engine, so they could be damaged by a long drain. Ray touches on this a bit, and his gizmo keeps the car battery from dropping below 9 V. 'Boat' batteries, also used in RVs with solar panels are better. I've never figured out how to set up a (safe, effective and optimal) system with an added boat battery in my car... or how to safely plug an inverter into the big traction battery in my Prius--which would be perfect if only someone would figure out how to do it and let me know. Where's an electrical engineer when you need one?
My Prius, parked but On, maybe the heater or AC, running my laptop... will run the gas motor ICE (internal combustion engine) for a minute about every 5-10 minutes. This never made any sense to me., until I learned it's to protect my 12V starter battery by topping it off o it doesn't get damaged. The gizmo Ray has seems to address the problem.
If I were going to charge the E-bike I don't yet have (and baring better information) I'd leave my Prius On and let it decide when to turn on the motor.
There are reliable stories of Prius owners, during power outages, using 12 V inverters (so not connected to the traction battery) leaving their cars On for several days so they can keep their refrigerators, basic lights, TV, computer on until power is restored. They use much less gas than their neighbors with noisy Honda generators.
what was the ending about??
You wont take your car battery down to 11.5 volts before it's buggered - 12.2v minimum if you hope for it to last
Isn't there money to be made selling us maps where charging stations are located or at least camp sites with cheap hookups. Most of us need to charge every 40 miles.
Not a fan of any of these using petrol. Definitely the pub or cafe work well although I’ve never needed to charge while I’m out. And I don’t take my charge cable anyway. Maybe I will do a long trip next year.
What about a goal zero yeti 1000 solar generator?
goal zero are not really a good brand to be honest.. very very overpriced to start with, with a high amount of warranty claims
I d definetly not recommend running your car battery down to 11.5V . That's below dead flat. A new battery might do it in an easy to start 4cyl petrol car but even a bit worn forget it.
Off grid at the pub lol and you have to bring your charger with you??
I love this whining comments on every emtb video 😁✌
HERE BEFORE 700 VIEWS!! AND IN THE 75th LIKE!!!
AYYY love watching you guys. best youtube channel ever1
Also battery’s are rated in amp hours , in theory a 50 amp hr battery should give a supply of one amp for 50 hrs or 2 amps for 25 etc , around 11.2 volts is as low as you want to go with car , leisure battery’s lower than that and could possibly give long term damage to the battery cheers Shane uk 🇬🇧
all lead acid battery only really have a useful capacity of 50% of what the label says.. example being a 30ah 12v lead acid, in reality your looking at 15-20ah at best
Your definition of off-grid is different than mine.
In the United States we call it the hood of the car you call it the bonnet
bad place to put a solar panel.. any sort of shadow or shade will have a drastic effect on its power output... the roof rack is pretty much halving his panels output. EMBN please let the guy know if you can :)
How to charge your bike with every option known to man. Haha. I was hoping to see a charge with some sticks, wires, and a hamster wheel at least.
