This is honestly very close to fullfilning all my requirements in terms of bms except I cannot get the precharge switch to work properly (needs to be unplugged). 200a smart BMS - ANT
I feel like there’s way more potential under the hood to currently don’t have the time nor experience to dive into it.
But it’s got a good form factor and a loud buzzer that you’ll hear through the casing.
It goes into a low power sleep mode when not in use and needs to be connected to a charger or a switch (which I haven’t figured out yet) for the ble module to wake up.
I’ve also used some other smart BMS’s on discharge for a couple years now with no issues (the precharge switch works and the smart features are decent) but the voltage wasn’t configurable and its footprint was huge.
