It depends upon whether you are using a BMS that’s designed for a bicycle or small loads, that uses mosfets to connect/disconnect the load and charger
Or whether you are using a BMS designed for a larger system (ZEVA, Orion, EVPower, miniBMS, etc) that uses contactors for switching load and charger Sent from Mail for Windows 10 From: Lawrence Rhodes via EV Sent: Friday, 22 May 2020 12:26 PM To: [email protected] Cc: Lawrence Rhodes Subject: [EVDL] BMS cell pairs It seems most battery pack builds use one bms per cell row. That is two or three batteries in parallel using one BMS. If I am using A123 batteries that could be up to 120amps for 2 in parallel. Must the BMS be rated for the full 120 or would I go by the rated amps of the controller which in my case is 40amps? How many batteries in parallel can I safely put on one BMS? Any recommendations for reliable BMS? Lawrence Rhodes -------------- next part -------------- An HTML attachment was scrubbed...
