BMS Wiring 7S 24 Volt 18650 Lithium Pack. Escooter Upgrade Part 2

- Hey guys,
In this vid I show how I wire a BMS to a 7s 18650 lithium pack for a kids scooter I found on a rubbish pile.
The lead acid batteries were dead, so the scooter was discarded.
I'm guessing they go SO much better on Lithium!
Thanks for watching.

Nice work
Thanks mate
Great video! Where did you get your charger? I want one..
Allen Light Thanks,
If you mean the charging module it’s this one

Great work. Did the balance wires come with the BMS? I don’t like how they’re all the same color. I’m sure I would mess something up without different colors.
Hi
Yes they do come with the BMS.
Maybe you could make some little stickers or mark the individual wires in some way if that would help?
Great video👏🏻👏🏻👏🏻
I cant find the module you use to charge the battery, please can you tell me where to buy it? Thank you
Hi
Sure, here it is.

You can probably get them from Aliexpress also.
Thanks for watching
You
Also how are you powering the charger?
Revin' my engine Jus with mains 240 v power. Usually would be solar but I don’t have my system set up currently
Nice looking batteries. Looks like custom made bus with some twisted copper and fuse wire for isolation in case of short.
Could you help me please
-Why do it in the positive AND the negative? Shouldn't be enough to do for ex only positive?
-what do you use as fuse wire?
-how did you calculate the thickness of copper bus?
You all prolly dont give a shit but does any of you know of a tool to log back into an instagram account??
I somehow forgot my login password. I would appreciate any tips you can offer me!
@Howard Dominick Instablaster :)
@Emmanuel Maxim I really appreciate your reply. I found the site through google and I'm in the hacking process atm.
Takes quite some time so I will get back to you later when my account password hopefully is recovered.
@Emmanuel Maxim it worked and I finally got access to my account again. Im so happy!
Thank you so much, you saved my ass!
@Howard Dominick no problem :D
Sorry if you mentioned it but does the bms protection board have over discharge protection?
Couldn't see it in the spec.
Hi, yes it does.
Thanks for watching
As I know all battery management systems (BMS) have overcharge and under discharge protections. That is the management otherwise it is a charging board or module.
where did you bought and which size heat shrink tube did you use? can you tell us the link please??????
Hi
It's fom aliexpress if you search large heat shrink you should find it. Can't find the link sorry ✌
When will you make the video on how to make the battery?
Hi I’m not sure at this stage. I’m very busy with work at the moment.
If I can I will ✌️
Hi total amperes?
Hi
I think the bms is rated to 20 amps Max.
But with other bms could do double that ✌
How much Ampere BMS ?
I can't remember could be 20 amp maybe
You scooter motor needs 24v in , why you bought 7s bms? you will have 29,4v with this bms right? i have a doubt with this in my RV project, why you didnt buy 6s 24v bms to have 25,2 v charged?? thankyou
Hi
I am intentionally over volting the motor, which gives better performance
Just need to be sure your top voltage doesn’t exceed the capacity of your controllers capacitors ✌️
29.4V is maximum voltage which drops of fairly quickly, it'll rest around 24V nominal voltage for most of its use (roughly), these motors can handle the extra voltages no problem
7s for 24v equipment works out perfectly, in most cases, with lead acid full charge or while charging can reach 28.8v and some cases even 30v, and 7s can safely go to 20-21v where most 24v electronics shut off! I'm home inverter, and battery bank us 24v with a 7s charge to 28.7v, 4.1v per cell! And the inverter shuts off at 21v, and can Handle up to 32v
