Hi guys! This is my first build. I ordered a 6374 motor, single setup and plan to build my own 10s3p battery pack. I ordered samsung 25r batteries and a spot welder.
1- I will configure the VESC to not discharge lower than 3.5v so discharge is not a problem but I think I should use a BMS for charging. I heard that even the cheap ones on aliexpress are sufficient. Is that true?
2- I also would like to monitor my individual cells - maybe add a battery cell checker instead of the voltmeter? But how could I balance them individually when they are unbalanced? Could I solder two 10s balance connectors? one to the BMS and one to balance them externally? My Imax I6 is only capable of balancing 6s
3- I also considered a BMS with integrated switch but heard that they fail a lot. Is this true?
4- Also - are the cheap chargers from aliexpress ok ?- like this 3A one: https://www.aliexpress.com/item/New-10S-36V-37V-16A-Li-ion-Lithium-Battery-BMS-PCB-PCM-Suitable-For-Ebike-Electric/32823734788.html?
