Get this https://fr.aliexpress.com/item/4000042522477.html and connect both battery that you want to use ton increase range.
To do this, make sur that the both battery you will connect got 36V and if you can, get the same AMP ( Example : 12 800 Mah ), try to get the same value on both !

So without BMS i cant do anyhting with this battery.lexfire wrote: ↑Mon Jun 14, 2021 3:50 amHello sir @Youhas ,
Well, NEVER charge a battery without the BMS, or it's gonna blew up if one cell is going upper than 4,2V ... The BMS is here to protect the cells of overcharging and Discharging ... If you say that the battery is 36v nominal and it's actualy 18,2V .. Be careful with that battery ..
To answer your question about different capacity ( MaH ), well, it's doing to work if you get a battery with 7.8mah with a 12.8mah for example, BUT, it will work as long as the first battery got the SAME voltage. And as you know, when a battery is fully charged it's 42V, and when discharging, it's 29V. So, try to get BOTH batteries at the same state of charged / discharged ..
