Good morning boys , i m a new user. In this period i m trying to contsruct a new battery with a new bms. My purpose is to built a 17s 9p with 21700 cells ( samsung 40t ). Now i would have 200 amps for continuous discharge ( 100 amps for channel , infact i have 2 channels ). i'm in trouble with the choise of the bms.
In your opinion which bms is best between:
- LLt power SP4S005-100-1-1-1 with the specs that i attach:
- Daly 17s 200A with this specs:
If you have another idea..
Thanks a lot
