Re: which BMS

the bms is for the battery,not the controller or motor. find out wich 18650 cell is being used and google it to see what its max continuous amp rate is, multiply that by the number of p and that's the maximum amp rating you want for your bms. if that number is 60amps get the 50 amp bms. find out th...

I'm not buying the battery separate from the BMS. The batteries I'm interested in offer either 30 A or 50 A BMS' built-in already. I'm concerned whether either will protect my system and if the higher is the better choice.

which BMS

All I need to know does it matter if I pick a BMS 30A or 50A with the 60V 20ah lithium battery pack I need to replace the original battery of my 2000W scooter. I'm a noob to electronics and just don't want to damage the controller that is rated DC 60V, Off Voltage
51V, Power 2000W. Thank you.
