Is it necessary to employ batteries with integrated BMS in parallel configurations?

Yes. A better approach would be to connect batteries controlled by integrated BMS in parallel to increase the current intensity.

1. Built-in BMS Limitations: When using batteries equipped with an integrated BMS, individual battery access becomes challenging without disassembling the entire battery pack. This limitation can pose challenges when working with parallel BMS configurations.
2. DIY Battery Assembly: If you’re assembling your own battery packs or are willing to disassemble and reconfigure existing batteries, it becomes feasible to connect them in parallel and employ an appropriately sized parallel BMS.
   It’s essential to understand that the key advantage of using a parallel BMS is the ability to maintain functionality even if one line or module experiences a failure. This redundancy is a fundamental feature of parallel BMS setups, ensuring that the system can continue to operate normally in the event of a fault in one part of the configuration.
