They also have a slightly more expensive (what's a few hundred bucks to get what you need?) model, the RB100 HP with an 800A peak discharge rating and a 1000A discharge cutoff. More in line with the cranking amps ratings of an FLA chassis/starting battery.
DISCHARGE SPECIFICATIONS
Maximum Continuous Discharge Current 100 A
Peak Discharge Current 800 A (2 s)
BMS Discharge Current Cut-Off 1000 A ±100 A (2.2 ±1 ms)
Recommended Low Voltage Disconnect 11 V
BMS Discharge Voltage Cut-Off 9.2 V (2.3 ±0.08 vpc) (4.2 ±0.5 s)
Reconnect Voltage 10 V (2.5 ±0.1 vpc)
Short Circuit Protection 200-600 µs
Just depends on your needs. They've got something for everyone there.
The RB100 has a little bit of a cushion that might keep the BMS from shutting off the discharge circuit at almost 330A, if I read the + or - thing correctly.
