48V 25Ah LiFePO4 E-bike Battery w/ Navitas cells-How far can I go? DIY your own battery, it's fun!!!

- In this video I build a 16S 48V battery out of Navitas LiFePO4 prismatic cells. 25Ah is a LOT of capacity for an e-bike. Since these are LiFePO4 (not very energy dense) it makes the battery fairly large but I have plenty of room on the back of my bike so I figured why not!!
I used a Daly 40 amp 16S LiFePO4 BMS for this build, but an ANT-BMS or a similar BMS with bluetooth connectivity would be preferable in my opinion just for convenience.

I'm planning out a 36-48v 50ah lifepo4 battery that can double as an ebike battery and a camping battery
I can't wait to try it, crazy range and a lifetime of cycles
Thanks for the courage, im going to overengineer the crap out of this ebike business
Just add a plug for camping Easy Peazy!
@@johndoe-sz4iq funny you say that
I just finished the build. 48v 72ah because those cells were the best deal. 4 kilowatt hours and a 1000w pure sine inverter
Im loving those cells....Cant wait to get my bank built with them!
They are one of the better battery impulse purchases I've made. Theres so many applications!
Absolutely brilliant video sir, you have inspired me to build a 60v 25ah battery using you video for my 1200w quad bike.....Thank you! 😊
I Built same battery Love it, I'll Post back with totals when i get the results Way better though then Ni CADS LAST 3 TIMES LONGER 40+ So far....
Great info!
Thanks for watching! 😉
I like the bloopers :)))
Haha thanks! If I get a laugh or two it is worth it.
Thanks for watching!
most 25 Ah batteries usually claim 40 miles range so this is lower than i was thinking.
Like the video allot, wish you would of shown the polarity of the batts when doing the buss bars:)
Stupid question, but if you made two such batteries in series, that would keep it at the right voltage but double capacity, right? So, that would make it a nearly 80 mile battery, if you pushed it as hard as you did in your test runs?
I'm asking because I've been watching the channel Drew Builds Stuff, and he made a camper for his ebike, and made a battery, so I've been curious how big a battery one could make, if they felt so inclined, knowing it would be part of the camper, and not on the bike itself. Obviously, towing something as big and heavy as a camper would cut into the miles, but I imagine you could build a battery with, say, four times the capacity as what you built, and it would have the power for nearly 100 miles, round trip, pulling a camper, on a single charge.
LOL I use a pair of vice grips for my third hand. Holds tight.
Solid tip. It'll be my go-to now! The pliers weren't quite cutting it. Thanks for watching!
It has been a hot minute, but I still recalled watching this video. I came into some similar cells: LiFePO4 3.2v 75ah 240wh. ...okay slightly more Ah maybe, here are the single cell's stats from EVE. I am assuming that the max charge and discharge rates stay the same in a 16s 1p battery build.
Max Continuous Charge Rate: 75a (1c)
Max Continuous Discharge Rate: 150z (2c)
30 Second Pules Discharge Rate: 225a (3c)
5" wide, 1.5" deep, 8.5" tall
Cell weight is about 4lbs.
Fully Charged 3.65v
Fully Discharged 2.5v
Operating Temp Range 0°C 32°F - 55°C - 131°F
70 km is one thing. The other is that you have 2000 cycles wity lifepo4 battery and still have 80% capacity. 2000 full cycles with 70km is 140 000 km range. Unreal.
The battery will most certainly outlive me!! People don’t understand just how long the lifetime is on these cells. It’s incredible.
Awesome battery I made mine from A123 LiFePo4 26650 cells and easily got 50 km I never did try to kill it
I just got my kweld put together. I can't wait to build some packs! Nickel strip is ready and waiting lol I have a bunch of 2170's that I got from battery hookup when they did their model 3 sale. Is your bike a hub motor? Thanks for watching!

Nice!
Amazing....I'm getting Samsung cells same 48v 25Ah ......and have a lighter 12" pocket bike 🤣 Hopefully I get over the 100 👍
Awesome!!!
Would that work for a 2000 watt electric Honda grom copy?
I'm soon to move to a town 46km from the one I'm currently in, and seriously considering an ebike for my daily commute (my job is in the other town). I can take back roads which actually reduces the distance by about 5km, and probably also traffic waiting time so by my estimates going 50kmh on the bike (as opposed to 100kmh on the highway in a car), it'd take between 45 mins to an hour (10 mins slower than my current diesel rig) and I'd need around a 1500w hub drive. To do this twice daily I think I'm gonna need a 2.5kW pack lmao. Your video just confirmed that for me (61km on 25ah, roughly calculate (40/25)*61 = 96km on one charge. Since distance is 46km, that means total daily distance is gonna be 92km with a 40ah pack)
Shudder...
Yeah at least an extra .5kw will gaurantee I'll have enough to get there and back every day with extra.
Do you think a 50ah pack would go alright? I'm looking at the 32120's purely because I can mould the shape of the pack to the bike frame. Anything you'd mention that I should know before going ahead?
Thanks for the video bro - very informative.
The two biggest questions are: is it flat terrain and can you charge your bike at work?
After that you will need to figure out amperage draw on your bike at full speed with you pedaling.(and without) Aerodynamics also play a role, I can shave an amp off the top speed draw just by leaning forward a little bit and not catching as much wind. Are you going to pedal with the bike or just let it do the work?
@@diyrenewableenergyelectron4996 @DIY Renewable Energy & Electronics The terrain is pretty much flat most of the way. A bit hilly at some points, but a small gradient of 3 to 5 degrees at most. Just a largely spread area.
I'm basing my calculations on flat-out 1000W. (I'm getting a 1500W motor just so that it isn't running at max power all the time).
A 48V pack with 50AH is approximately 2440Wh. Take 1000W motor into account and I get: 2.44hr. Based on your speed of 30mph (50kmh) with 1000W, we can assume 2.44*50=122km range.
1000W/48V= approx. 21A max.
My idea is to make the bike capable of running to work and back on one charge, but I've just sorta realised that the 32120s are nowhere near small enough unless I throw a touring rack on the back. What do you think? Is there better options for energy density?
I'm going to pedal, but I want to be able to do it without pedalling with ~20km reserve to add.
My opinion is to do a 13S10P battery with 21700 cells. I would do either 5000mah(preferred) or the 4800mah tesla model 3 cells that battery hookup has for sale. That will yield you a 48-50ah pack and will be about as energy dense as you can get. At full speed I am drawing 16-18 amps. I weigh 130lbs tho. Once the bike reaches max speed (the maximum rpm the motor can rotate for that voltage) the amps tend to drop from the 30 amp max.
I think even slight pedaling will help. Just moving your legs without pushing hard at all can usually drop an amp off the draw with almost no work. I put a rack on the back of my bike to hold my battery and you could do the same. I think a 13S10P battery will be an exceptional option. LiFePO4 is kind of out of the question since you have such a large distance to travel and it is less energy dense.
You would basically be building the big powerwheel battery I built just larger.
@@diyrenewableenergyelectron4996 13s? Oh, you mean LiPO? I do like the look of lipo batteries in regards to energy density. I just worry about the safety aspect.
Do you think it's worth going LiPO? I know the lifetime cycle count is 500 for lipo as opposed to 2000 or more for a lifepo4. I'd be doing one charge a day for 200-300 days of the year on average probably, so wouldn't that last me only like a year and a half?
Do you believe LiPO's are safe enough for this purpose? If so, is it just a case of performance(lipo) vs longevity(lifepo4)?
It is entirely possible to do a LiFePO4, but you would need to do my ebike battery as a 2P instead of 1P like I did in my video. Your battery would weigh 46 lbs (21kg). It would also be twice the size of mine, it wouldn't even fit in a backpack or on a rack. You would need a trailer at that point. A trailer is actually the first thing I thought of because that would open you up to building like a 100+ah pack pretty easily. I have used a trailer on my bike, I know it will pull it. I didnt go full speed though. It would obviously cause a higher amp draw but it may be worth it if you draw 25 amps but get to haul 100Ah instead of 50 Ah.
If the size and weight is no problem then I would say go for lifepo4. It is my preferred chemistry.
The other option which is far less ideal is to ride at a slightly slower speed. For example, you may be able to get away with around a 25Ah battery like mine if you ride at 25mph instead of 30mph just because of the lowered wind resistance.
Lithium ion is safe if you treat it correctly. I only suggested it because of the demanding situation you have. I'm loving this discussion, brainstorming is a blast.
from where you bought does batteries ..?
Some people swear by the little jigs that hold all the different type of RC connectors and they look helpful but I'm cheap so I just grab a small alligator clip and it fits inside the hole of one of the female bullet connectors. Then I take one of those mini adhesive hooks and have it stuck to edge of my desk but actually I should stick it to my ghetto "second floor" of my desk (just a table with the legs chopped to 12-16" to give me more square footage to put stuff and there is one drawer on the top table. I pulled some LED's out of free Harbor Freight light and put them on the bottom of the drawer. just have the wiring inside the drawer going to 2 18650’s in parallel. 6-8 hours runtime but I’m going to double it so I can leave it on overnight and not kill the cells)
So wherever you put the hook, stick the alligator clip on the hook where the wire goes in. Now ya got a steady “helping hand”
😂 you sound crafty! I know how that goes. Modify to make due. Thanks for watching and commenting.
@@diyrenewableenergyelectron4996 edited the comment fix the cat walking across the keyboard. Apparently she doesn’t want you to know this.
Just make sure to use flux inside the XT bullets and have both the XT and wire tinned. If the wire is borderline too big I will sometimes use a tiny alligator clip to compress the wire when it’s heated.
The tinning part is solid advice. Quite a few of my videos show me struggling to solder the connectors because I didn’t tin the wire/connector. It makes all the difference!!
Just a question, idk if you said it how much did these batteries cost and did this project overall cost? anyways reallly good video dude!
At the going rates for raw cells I would say this is a 200-400 total dollar battery, depending on the grade of the cells
Very COOL! and a big thanks for this. You inspired me to build a pack using the 32650 6Ah LIfePO4 battery hookup sells and I was wondering if you had an idea of what your average speed might have been and what the actual watt-hours might be, as well as the total weight of that monster pack?
Thanks.
Average speed was around 30mph at full speed, but your range increases significantly the slower you ride. Actual watt-hours is around 1,250, maybe a bit more. The pack weighs close to 11Kg or around 25 lbs. Its kind of obnoxious lol. What size pack are you building with the 32650's? Thanks for watching!
@@diyrenewableenergyelectron4996 Thanks Cody. I'm considering 16s, 17S or 18S (2P) packs for an e-trike and e-bike, but I'm finding limited BMS and Charger options for 17s and even less for 18Ss. I'm currently looking into the JBD-SP20S001 BMS but not finding any 18S LiEFPo4 specific chargers and I'm wondering if it's ok to use a DC power supply rather than a charger and let the BMS handle the charging?
If you have any thoughts you care to share I would look forward to your input. Thanks.
I think a DC power supply would be fine so long as it has a CC-CV setting. Most do. I know for benchtop testing and preliminary charging I have used a power supply and it has been fine. What is your reasoning for wanting to go with a 17 or 18S as opposed to the 16S? Are you sure your ebike kit will handle the higher voltage?
@@diyrenewableenergyelectron4996 When I look at the difference between full charge and Nominal and how quickly LiFfePo4 cells drop to nominal and the voltage Sag on a 16S 2P pack, I wanted to try to keep the nominal pack voltage at or above 48V under load, and I'd like a bit more 'punch'.
I was planning on using a controller rated for 72V. 52V Li-On packs in my testing seem to provide more even performance over the charge.
I've been running a 1000w rated direct drive hub motor on a 72v 10ah Li-On pack on a Vector Storm frame and the performance and range are noticeably better than on same cells and watt hours in a 13S configuration. Motor seems to run cooler at the same power as well, and we're getting better performance on the 1000W motor at 72V then a 1500W motor on a 52V pack and 35A controller with less weight too. The 1000w hub motor seems to be wound for more speed and we get over 45mph on a fresh charge, while the 1500W motor on a 52V pack tops out about 38mph.
As 18S 2P LifePO4 would be about 65V charged and about 55V nominal, and 44V Depleted, which I'm thinking should give good performance all the way.
Epic!!! Clearly there had been a lot of thought put into the decision, that's awesome. You're likely better versed in it than I am lol one thing you can do to avoid voltage sag is find higher C rated cells. Lower internal resistances give you higher discharge rates with less sag. Let me know how things work out! Sounds like an exciting project.

I'd like to replicate this build, but I want the configuration to be split down the middle like panniers. I wonder if I can use a wire to series the batteries that is longer than the bus bars, so that it can straddle the back rack in a bag or a case...
I would think so. The configurations for these types of batteries are only limited by your imagination. You can do all kinds of things! Thanks for watching!
I built a 36v version, 20Ah, used cells. Haven't run it till BMS cut-off, yet is already over 60km. I charge it with a solar boost controller at 42v only.. considered full at 90%, recharge when is abt 30%. Bike is a 500W front hub.
Awesome!! That’s excellent range for a 20ah battery
My 48v/20A sealed lead/acid battery Etrike gets 60km range @ 50kph.. Newer batteries are 48v/32A and 48v/60A batteries now cost $150 to $200 come in two boxes ready to use or charge indoor..They last for about 4 years...
That’s awesome! Thanks for sharing.
So a 48v 25ah battery for under $200? Nice! Hopefully battery hookup will get more cells in.
Which BMS was that?
It was a Daly 16S LiFePo4 with balance. I think it was 30 or 40 amp discharge. Very reasonably priced. Thanks for watching!!
How much did the cells cost I've been looking at AliExpress pre-made battery I have 36 that normally is 10s . I think with life po4 it's 12s for same voltage . With my old li ion battery 360wh I get about 30 miles at 10mph. I would like 25a 36v ish
I bought these cells in boxes of 30 and each cell was $11 plus shipping. Battery hookup had individual cells available but they have since sold out. They also had “topband” cells which were the same capacity and very similar. Keep an eye on their website, they post stuff often. A 12S battery would be great for a 36v setup. Thanks for watching!
Hello I'm thinking of making a 72v one. Your thoughts? to connect xt60 together then solder hot fast flux is your friend
Mine is only 48v and it sparks pretty heavily when I plug the bike controller in (charging capacitors). If you go 72v any capacitor charging will cause more significant sparking and you will want to check to see what xt60 connectors are rated for, voltage wise. I think 72v is too high for them. 48v probably is too lol
I was wondering if halfing this would be possible? 24 volt battery and 24w motor?
For sure! You would just do 8 in series instead of 16. There are off the shelf bms options from many suppliers. Thanks for watching!
Great video, do you have photos of where you mounted the battery on the bike? I want to mount mine down as low as possible to keep a low CoG. To do that I was thinking of splitting the 2 rows of your 16s1p on on each side to balance the weight but the 16 BMS wires would be all over. Then I thought.. maybe two 8s packs with individual 8s BMS in each pack connected together in series. But that could lead of unbalanced packs, no?
I actually ended up buying a cargo rack that goes over the rear tire and plopped it on that. You can DEFINITELY tell the weight is back there. Keeping the battery lower if possible is recommended. I just went with the easiest method lol. Splitting it into 2 8S batteries might make it easier to mount lower but some BMS's dont like being wired in series and you are right about balancing them. May have to connect the two batteries in parallel from time to time to balance the two pack voltages manually.
Thanks for watching!
How many watts was your bike motor drawing on average? What's the watt rating of the motor?
What type of motor is it? Gear or plain hub motor? What was the average watts used per mile? I was thinking about buying those same batteries to use on my cargo bike. Im curious if those 6mm.battery posts are aluminum or ? If aluminum, I wonder how well they'll hold up...
Wattage depends on speed, I usually watch the amperage draw but generally it is 1-2 amps at 10mph, 2-3 amps at 15mph, 4-5 at 20mph, 10-11 at 25mph, and 15-17 at 30mph.
It is a 1500 watt hub motor, no gearing.
Not totally sure about wattage used per mile. It is highly highly dependent on the speed you ride at.
The posts are stainless steel from what I can tell.
Thanks for watching!!
Hi. Nice build. Where do I buy these cells? In Europe?
Building a 16s 2p 48v battery with headway lifepo4 cells (200 amp continuous discharge) since the prismatic are unavailable at a decent price. My objective is 10-15 MPH with some pedaling on moderate hills and total distance of 10 miles or so. The Volamart 1500 watt hub motor package says 14.5 Ah is required & their 1000 watt version requires 11.6 Ah. Seems like the Ah should only relate to distance traveled. Do you think either Volamart option would work and which do you suggest? Also, is a 30 amp Daly BMS powerful enough? What amp fuse or circuit breaker should be used? Finally, does my battery pack need ventilation & what gauge wire to the motor? Thanks!
What Ah are the headway cells? I know there’s a few sizes. I think 10-15 miles with some hills and pedaling somewhat to assist should be no problem. The 1500 watt motor draws about 30 amps peak (10 gauge) and the 1000 watt motor will be in the neighborhood of 20 amps (12 gauge).
I think both will work fine, but I would recommend the 1500w motor. It may also be worth looking into a geared motor as opposed to a direct drive motor like my bike has. The geared motors produce much more torque and the hills will be a breeze. The direct drive motors can generally do the hills but they have a much harder time. I didn’t put a fuse or circuit breaker on mine. Live dangerously right?
I used a 30amp Daly BMS on mine and it works perfectly. If you went with that size or even a 40 amp BMS I think you will be very happy.
Thanks for watching!
is it possible to connect 24 of these cells in 16s configuration? 16s1.5p?
You can only build a 16S battery in multiples of 16. 16 cells, 16S1P. 32 cells, 16S2P. And so on. There is no way to set up a battery like you describe. What are you using your battery for?
"i don't have a bus bar ready" there's one laying down at the bottom left corner of the battery....
Maybe it would work for an electric motorcycle lots of room In the grom cologne
Do i need bms if i use lifepo4 cells when i build 30ah 36v pack
Yes, you should use a BMS anytime cells are being series connected to ensure the cells state of charge don’t wander too far off from each other and to protect the battery/cells in case they do. Thanks for watching!
We build a 90 volt 20 amp hour mega pack for the Walmart Wednesday Night Wheelchair Races. We use 16 hoverboard motors, 6 in front and 6 in rear a 2 one on each side.

Not entirely sure what I just read but thanks for watching! Sounds like you have a party lol
Quick question Where do you get your chargers and how do you know what voltage to use? I am currently planning to make a LFP battery my own but don't know where to get the chargers I am going to use 16 cells in series at 3.2 volt
You can take your max cell voltage (3.65) and multiply it by the number of cells in series to get 58.4V. If you look on Amazon for 58.4v chargers you will find a bunch.
@@diyrenewableenergyelectron4996 Alright thanks for responding so fast!
No problem! Hopefully it helped you out
Hoping you can help me configure (96) LifPo4 25 Ah TopBand prismatic batteries into a 24V system that uses (2) Overkill 8S 24V 100A BMS. Aiming for 300Ahr / 7Kwhr. thanx Bob
Why do you want to use 2 BMS's?
@@diyrenewableenergyelectron4996 Well........ in lieu of the fact 1 BMS is designed to handle 8 batts and I am configuting 96 batts??
A BMS is designed to manage one battery. However, when you parallel cells together they become a single cell electrically. So, for instance, in your case you would parallel 12 cells together into 8 individual parallel strings. Now you effectively have 8 300Ah individual cells. The voltage of each is still 3.2 nominal, you just increased the overall capacity by paralleling the cells together. Now that you have 8 sets of 12 cells in parallel, you can wire these big cells in series to get your 24v. You would only need one BMS because electrically speaking, you only have 8 cells at 300Ah each. A single 8S BMS will work for you. If any of that didnt make sense let me know, I can try explaining differently.
Is this a lithium ion battery ? Were you going 25mph and higher most of the time ?
It is a lithium iron phosphate battery which is technically a lithium ion battery but has vastly different characteristics than typical ebike batteries. The voltage is different, theyre safer, and last a lot longer.
Edit: yes, I was trying to max out the bike for this range test so I was riding 26-30mph the whole time.
Thanks for watching!
Hi there mate or anybody else which might no the answer I'm wondering what a 60v 25ah life p04 might give at around 20mph?
how many miles it would give?.........
Its hard to say, because its entirely dependent on riding style and how fast/aggressively you ride. If you ride at a consistent 20mph on flat ground I would expect a minimum of 35-40 miles of range depending on the weight the bike is moving.
@@diyrenewableenergyelectron4996 thanks yh I just purchased the 60v 25ah... so with a hilly terrain could expect half that ay?
@@luq9444 I think thats a fair baseline to assume. Once you get out and ride, you may find you get more mileage though. Hills definitely suck more power. Do you know if your hub motor is like mine or is it geared? Alot of the geared motors have significantly more torque than the direct drive motors.
I still cant to make a decision for using li-on or lifepo4 for creating a e-bike battery.Pff its difficult.
What is your goal? Longevity? Small size? Efficiency? Weight? What do you want out of the battery as far as range?
Size and weight is not an big issue.But longevity does and, Efficiency.I will create a custom size box on the back of the bike.Now my range on powersetting 4 is around 40km on 7s4p 12ah 18650 li-ion cells at 24volts.Maybe some lifepo4 26650 cells 8s12p JGNE or EVE 3.2ah cells will do.My goal is around 120km.Or maybe i should consider 21700 li-ions.What do you think.Thnx

You’re welcome!
How long do they take to charge up? How do you charge such a rig?
It takes a little over 6 hours to fully charge from completely dead. I use a 54.6v charger that puts out 4 amps. It's a 14S li-ion charger but works for this 16S LiFePO4 battery just fine. Thanks for watching!
@@diyrenewableenergyelectron4996 Only 4 amps to charge? How is max amps for this battery?
You could charge faster with a higher amperage charger, I just bought a 4 amp charger. The cells are rated for 25 amps continuous easily and can actually do 75 amps continuous. I made a 12v battery in another video and discharged 4 cells in a 4s1p configuration at 900w until the inverter shut down. They perform very well. Thanks for watching!
I was trying to replace my Electric ATV's 1500w 48v (4x12v20Ah lead acid) battery and I was wondering what LiFeP04 battery you could recommend to replace my old acid battery. Any help would be greatly appreciated.
Actually, the cells in this video would be a good replacement. You would need 16 cells in series and would gain about 25% capacity over the lead acid batteries. Basically build the same battery I built lol

@@diyrenewableenergyelectron4996 Thank you very much. Is there a already built battery pack i can purchase? I am terrible at the DIY part of battery building.
Certainly! You can look into 13 S (48v) ebike batteries, or 14S (52v) ebike batteries. Theyre pricy but have what you are after!
Oh wait, I noticed you wanted lifepo4. Most are lithium NMC
Go for a lithium pack dude. Lead acid battery era is long gone, Lithium-Ion / Iron-Phosphate is the best way to power any electric vehicles, they are expensive initially, but cheaper than replacing the lead-acid batteries over time. Lithium lasts much longer, most amazing thing is they charge very fast like in 3 hours with proper charger, and importantly Lithium batteries are fraction of the weight of a lead-acid, I mean it 1/10th of the weight of the lead-acid of the same capacity and much smaller in dimensions, so much smaller. I replaced all my dirt bikes and ebikes with lithium packs and they work wonderfully.
where did you buy it bro please i need them :'(
I picked them up from battery hookup. They get them back in stock from time to time. How many do you need?
