That shortie is adorable
Nice little step up charger,i could see that using it with my 52v Ebike and possibly a 100w solar panel. Thanks
A 12v pannel gives out 18 to 20 volts. The 36volt lithium battery of this scooter needs 42 volts exactly for full charge. If you use a 200 watt solar panel in full sunlight, it gives out 10 to 12 amps of 19 volts. Making it 42 on the boost MPPT will give you the proper 2.5 to 3.5 amps for charging which is similar to what usually the wall AC charger comes with.
It would be best to not fully charge it with the panels, full charge for balancing could be done with the original wall outlet every few months, but maybe only having two panels to keep it above 40% charge could be good
@@RinoaL It all depends on how it's designed. Many battery packs have balance circuits built in and can prevent over charging as well.
I'm not sure what percentage of chargers have built in voltage and amperage limits for scooter and electric skateboard battery packs.
The 4 skateboards I have worked on all had different voltage chargers but the packs were all built from 18650 cells.
Every stock BMS that I've seen in one of these just takes a bit off the top of whichever cells are highest. Perfectly fine to do that only once a year or half a year. You don't need to balance the batteries very often.
Haha, a "short". Good one, guys. 😆
I so hate how all these things are made with charging that locks out operation, and ultra slow chargers that charge slower than discharge. There's no need to do that, and it can pretty much always be fixed by bypassing the mainboard and wiring the charger directly into the BMS.
Three of the flexible 30 watt panels would get you the size and voltage you want. The sponsor might have them!
flexible panels would be hard to mount on the scooter I think
@@RinoaL They’re still fairly rigid, just not nearly as bulky/heavy. At scooter speeds, they should hold up.
That's a great idea, I want to build a pushcart, there are some useful concepts around there. But I'm afraid my fat 170 pounds backside would need like a 72V, 5000W motor....
Windshield wiper motors have a lot of power and they are geared, maybe you could get one of those for free and run it off 12v!
You need big shelves!
I'm actually putting up some normal sized ones, and had somebody offer me some really big ones.
2nd
For 36v and that charger you want a min of 100W. I not sure if true but some people say charging with too little current is bad for battery. I find 100W just gets ya full charge current in perfect conditions. I only charge with a 30W panel cause there charging a 12v bank and then I use an inverter from there with the E-Bike's normal wall charger. And I only started doing that cause I had the inverter for other things and thought at least I know it's getting the right charge this way. I think My MPPT and a 100W panel charging a 48v setup was only able to get about 1.2amps near low battery and .9Amp near full charge. Prob do a bit better than me on a cool day cause I'm too far up north.
You cant cause any problems charging too slowly for lithium, thats more of a lead acid thing
I would always charge the battery with the values specified by the manufacturer. Then the battery should last a long time.
@@michaellichter4091 absolutely, and if the battery has a short life, you can say at least you used it right.
When I am on the boat, I used a portable solar generator, it's only a 650w unit, but today I was running a 300w sander and keying the old varnish on both sides of the boat, ready for new coats, I started on 100% and sanded then varnished one side, when I looked it had charged back to 98%, the same with the other side, and on each side I had spent 15 minutes sanding at 300w, for the power I used on the boat (mostly charging a phone and a tablet, my solar generator is perfect.if it drops to 70% overnight charging stuff, next day it just needs a few hours and it's fully charged again
@@grendel1960a I need something like for my shed, I really don't need much cause all my stuff runs off batteries but there might be a day when I want to charge everything at once and not run the power cord from the house. To be able to walk into the work shed and just plug all chargers in at once would be awesome. I just need a bigger 12v bank for the inverter and then a bigger inverter, I guess. I do have about 21X 12v 20Ah batteries laying around. 🤔 if they were new that's 420Ah lol
not gonna lie if that was Australia that scoptter would be found in the bottom of a river
Same in california lol
