Battleborn batteries are selling 100 amp hour modules for $950. The batteries have an internal BMS whive has a much lower parasitic draw compared to what RT used. They claim that the BMS draw is in the under 1 mA range. It would be worth an inquiry.

Cool! Thanks for the info for sure. Sounds like great news for most people, maybe KS2 is really committed to working out all the bugs now, since without this product there is no KS2!
Today I'm adding a feature so the cabin runs directly off the engine when the weather is too cold for Lithium to immediately power up.
What feature needs to be added for GU support of the cabin loads with the battery charge terminal shut down? Won't the GU do this as is?
Ecotrek Aktiv cabins are only powered by the GU through an ecotrek. Both charge and discharge relays must be closed. Are Ecotrek RTs different?
After looking at the electrical diagram, it looks like you are correct. The GU powers the battery charge port which is common to the discharge port and cabin loads. But if the battery charge port shuts down in a low temp situation, the GU can't see the cabin loads.
An existing cabinet cable and 150 amp sealed circuit breaker is relocated under the ProMaster beside an Ecotrek discharge-side. A new 6-gauge cable is routed from the 150 amp CB, through the floor and to the battery ON/OFF latching relay.
I didn't find a simple undervolt protector at blue sea.
This would work
Victron BatteryProtect 12/24V-65A https://www.amazon.com/dp/B01N6ATT8C/ref=cm_sw_r_cp_apa_i_5E9LCbS1WD3S9
The DC max 50amp and hopefully subzero cold is a rare problem. How about a $15 50 amp CB used as a switch? The UG will be running at the same time if we are powering more than the led lights.

One consideration I'd guess is to not impede the primary function of the AGM boosting the LFP's. Could a low voltage disconnect ever interfere with that for example?
Was the 150A a typo - should that have been 6 AWG & 50A and not 6 AWG & 150A?
