Question OK, I know that you're smarter than I am - please explain.

Bruce, I *was* thinking of that, because the "disconnect" logic of the internal BMS seems very comparable to the alternative of an external "battery protector". (Both alternatives include a circuit breaker, of course. But the Circuit Breaker will primarily protect the connecting wire from overload, because the battery itself is capable of 100A charge and discharge rates.)

Do you know of battery protectors which can offer tighter shutdown voltage limits, AND work without requiring connection to the (unexposed) BMS? (Some which I looked at, such as Victron, depend on a separate BMS to make all the decisions, and use an explicit connector monitor disconnect/reconnect signal wires.)

For me, and other interested TM persons: Can you explain with a bit more detail? I don't understand your warning. Thanks in advance!
