High Current
The current exceeds 100 (+/- 5%) Amps for 30s or 200 (+/- 10%) Amps for 0.5s (this is interpreted as a short circuit)
this means NO large inverter loads period..
it means 1200w max peak for 30 seconds
no MW, no coffee maker,
maybe a small toaster will be OK
don't buy an inverter larger than 1200 peak watts
you can't use it, not with one battery
more batteries in parallel means you can go longer
but that 30 seconds, could be a deal breaker
(2) batteries 200amps for 30 seconds, but you might be able to run 100amps
50 amps per battery for enough time to warm something up, like a cup of coffee
Turns out those specs are for the 50Ah battery. The 100Ah (BB10012) battery is double that, and you can parallel them.

two BB10012 batteries mounted in parallel can deliver 200A continuously and 400A for 30 seconds. Three BB10012 batteries mounted in parallel can deliver 300A continuously and 600A for 30 seconds.
I still have no idea how you set up a battery charger to terminate the charge with these things. Or even if you need to. Maybe just let the BMS handle it? Would a Meanwell PS set to ~14.6V work?
Battleborn lists the new Progressive Dynamics LiFePO4 chargers as compatible. They charge to 14.6V and:

The system was designed to sense voltage on the battery and will taper the charging current as the battery becomes charged.
IOW they don't rely on the increasing battery resistance to taper the charge as with a standard lead acid charger?
Brulaz if you haven't seen this post at the airstream forum it might help with your questions. Around post #31 is where a Battleborn partner starts to explain/ answer questions.
