Maybe third time will be a charm for Progressive Dynamics?
This is why Elon is so successful. He goes right to the solution. Engineer the product direct to the needed parameters. No hundred year legacy to adapt.

The victron BMV-712 has a relay that can be used in charge mode, requires a pair of wires go to the PD charge converter. This is how I have mine installed, it will turn on and off the charger depending on state of charge...no float.

. . . At ~13.6VDC from my 45A-capable Progressive Dynamics converter/charger with very short 4AWG wiring, my 100Ah x 2 BattleBorns at 50% SOC choose to pull ~4A total. At 13.6VDC, their thirst for current is minimal . . .
Interesting. We have the same PD 45a converter and get a steady 20-25a of charge current at 13.6v charging our 200ah LifePo4 pack from 10-90% SOC. Get 45a charging at 14.4v from 10-95% SOC.

I can carry two group 29s in my AF1150.

Are they worth it?


Yes they are worth if you need power and don't want to run your generator. I have 3 each 100Ah BattleBorn Batteries along with 480 watts of solar. I use Renogy DCC50S 12V 50A DC-DC On-Board Battery Charger with MPPT to manage the 12Vdc to dc side and solar input (MPPT). I need this kind of power (storage) due to the fact I've a 12Vdc compressor refrigerator as my biggest load.
