How do you know what size BMS to get?

What size BMS do I need? A BMS with enough cell taps for each cell in series is required. If you have a battery pack with 100 cells total with 50 in series (and 2 in parallel) at each level, then you would need a BMS with at least 50 cells.

What does 3S BMS mean?

How do I choose a BMS for lifepo4?

The BMS will have both a maximum charge rate and a maximum discharge rate, the latter more to protect the BMS, the former more to protect the battery. For example, if your battery specs state a max charge rate of 0.5C then the BMS for a 100AH battery should be set at 50A.

What is 50A BMS?

A . 5C cell x 100Ah battery should contain a 50A continuous draw BMS. This means that the 100AH capacity can only be drawn safely over 2 hours for a . 5C cell and that the maximum draw you can place safely on the battery is 50A.
