Tom,

Show me a bms that allows a draw of 240 amps from a 100 amp-hour battery?

My future bank will allow 9600 amps. Not that I'll ever use that amount of current.

Your needs certainly are out of the ordinary. I have a 170ah Renogy drop-in lithium with built in BMS that I purchased two years ago from Walmart for $970 plus tax. I'm never in a situation where the battery temp will drop below 32F. I have 400 watts of solar and in two years may have run my generator 6 times to charge my battery after a couple of cloudy days. This does not include times that I run the generator to use my microwave or A/C. I don't have to do anything to the system. About the only thing I have to do is turn my inverter on when needing 120 volt power.
