One important thing to consider if you are planning to make this battery for your EV. As much as recycled Lithium cells may work and are OK, their lifetime wouldn't be anywhere near as fresh, new 18650 cells. Motors as such that drive us forward require a good deal of power, so if you're serious about range and power, it's best to go with buying from a quality seller of these new cells. With that said, I hope you guys found my video helpful! Under the same making process and connecting, all that should be different for best performance is new cells.

Nice work. I pretty much replicated your battery using cells that I had lying around. These came from scooters and were 2000mah originally. When I tested them they were around 1700mah, with an internal resistance according to the charger of something like 70mohm. I am a little disappointed with the end result, the "kick" and uphill performance is less than with the original lead acid batteries. It was still cool to do, but I have now bought a box of "good as new" EVE cells with 2700mah capacity. I wonder if they will perform better, I am a bit suspicious of all of the specs of cells out there. I hadn't expected for it to make a huge difference, but it kind of seems like it does.

I would not tell people to use cells taken from laptops. They often have too low of a discharge rate for an kind of a PEV. Some cells have discharge currents as low as 2-4A when new but after being used their internal resistance will double and that will affect their discharge rate. Even with 5 cells in parallel they may only be getting 5-10A out of the pack. This is the part of testing the cells where people advise testing internal resistance but an RC3563 or YR1035+ is $45 on Aliexpress and $60 on Amazon. You can’t rely on IR readings from chargers, they are wildly inaccurate. You can do your own DC IR testing manually but it’s time consuming and prone to human error. If you want to use cells for a scooter you can buy LG MJ1’s or Samsung 25R’s from 18650Battery Store for $5. I think Samsung 40T’s are on sale for $4 right now and they are nearly the best 21700 cells out there at 4000mah with a 30’ish amp continuous discharge

Hi. Thanks for watching! I did this correction on purpose as these cheap BMS boards typically cut off if the load is drawing more than ~3A. The motor was drawing more like 15 amps or so which meant I could only use the BMS for balance-charging the battery. About over-discharging, it's more about feeling when the scooter has gradually slowed down to a lower speed after 20 mins of use. Knowing how low you're willing to drain the battery is key here. Over-discharge protection on a BMS designed for EVs would have to have a system cutoff when the amperage exceeds a certain high value such as 17A in my case. Cheers, Max.

Just bought one of these scooters, and finding your videos has provided me with inspiration (in fact, your videos, amongst others, are one of the reasons I decided ro go for this scooter - and its cheap price lol)... But there is one glaring error you've made that I feel compelled to point out!!! You say there is no access to the rear tyre and that this is a major design flaw - NOT TRUE! Inside the handlebar of the scooter there is a inflation extension, about 2 inches long. If you look at the rear chain guard, there is a hole. If you look at the sprocket, there is also a hole... If you rotate the sprocket and the wheel to line up the holes with the one on the chainguard (turn the wheel to line them up with the inflator screwthread) then you screw on the adaptor to the tyre and then you can easily connect to your pump. Instead of there being a design flaw, Razor really thought this one through and came up with an elegant solution. Of course it does help if you had the manual or you knew about the adaptor inside the handlebar grip. After I saw your video, I happened to notice the adaptor thingy on a subsequent Google search, which made me look at the rear sprocket and wheel more closely. Voila, there's the holes, and they all line up when you rotate the wheel!

The problem of not having enough current is fixed by using a correctly rated BMS.
@MaxImagination8 ай бұрын
I bypassed the BMS for output due to the BMS not allowing enough current to flow so the motor can run with a person on it. The BMS is set up in a way only for managing charging. I know it's not perfect, but it works.

Is it ok to use the original charger that was meant to charge lead acid for the lithium batteries?
@MaxImagination Жыл бұрын
Yes, I have had no issues with using it to charge them myself.

There is a lead-Acid battery cut-Off on the old controller, not sure how the lithium would get to it s lower limit
@MaxImagination Жыл бұрын
The charger might be mismatched as told as well from others, but it has worked fine for my battery so far. Though, it would be worth trying to instead charge it with a proper Lithium battery charger.

Max, do you like the Razor Scooters in general,? and why? not simply because of more easily modified? Like their chain drive? good power up hills? Thanks
@MaxImagination Жыл бұрын
Hi there. I generally have always liked Razor brand scooters for their fat and wide tires, spacious decks/platforms, and ease of changing out parts. They aren't the fastest in the market, but they sure are fun cruisers and good for entry level riders like myself. However, better battery technology and proportional/variable speed control would have been good to have in these scooters, but sadly, they're more on the toy side. Still, great fun riding on these type of scooters. Cheers!

Hi have you had any issues since you built this battery pack?how long does it last when full charge?
@MaxImagination Жыл бұрын
Hi there. Yes I've had one major issue which is the cells completely dropping in voltage after months of use. Not able to charge the battery pack or revive it. Could have something to do with the BMS or that I over-discharged the battery pack. In any case, this was probably my own fault. I don't see an issue if you were to make it, I do though recommend using brand new cells. With a full charge, the battery lasts me 20-30 minutes on the E-scooter

So I can make a 7s battery and charge it using the existing charger?
@MaxImagination2 жыл бұрын

@derdrolftesinn Жыл бұрын
Why dont they use the correct Voltage labeling Battery Packs? 24V is sometimes 6S, sometimes 7S. This is so important when for example choosing the right charger. The charged endvoltage ist very Importand if 6×4,2V or 7x4,2V. Nether the product of 3,6/3,7 nor of 4,2 fits the Voltage of 24 or 48Volt Ebike/Scooter Systems. Only 36V fits 10×3,6V. Does anyone know why?
@MaxImagination11 ай бұрын
Yes, that can be quite confusing... What I would do is know that if the battery pack's voltage is 7S (25.9-26V) I'd find a charger that is 1-2V higher such as a 28V charger (from old E-scooter) and use that to top it up. Even better would be to charge such battery pack with a balance charger that can handle up to 7 cells and choose the cell configuration before charging. 24V just seems to be a convenient way of naming these packs for compatibility with other products.

@@MaxImagination you are right. Comming from RC Models, it confuses. In RC, it is simple. A Lipo is 3,7Volts. Times 6 is a 22,2V Battery, Endvoltage of charging is 25,2V. A Li-ion is middle 3,6v, Times 7 is 25,2V. I have to know the number of cells for choosing the charger and set the charging voltage. At a "24V" Battery, this is not given but needed.

@@kanikipk2814 It's a good replacement to those Lead-acid batteries which used to sit in the scooter before as Li-Ion cells tent to have way more recharge cycles. It is a bit more powerful than before with new LD Acid batteries, but maybe not as much since I used recycles cells. That would be one thing to note for others who will make such battery, don't use recycled cells if you want full power.
