12v/24v charger

[Splatterman]

Current set up is 2 12.8 v 200 AH LiFePO batteries in parallel to make a 24v system. My WFCO WF-8955-AD only charges 12v what is the best way to charge this system on shore power? Off grid is charged by solar.

I think you meant to say that your batteries are connected in series to make a 24v battery.

Regardless of whether your battery is 12v or 24v, I like the Victron IP22 charger to charge from 120v shore power. The charger is fully programable.

Yes they are in series is correct but I still don't think a standard 12v charger will work I will definitely look into the victron

to make a 24v system.

Out of curiosity, why 24 volts?

The Victron IP22 charger will charge a 12v or a 24v battery.

You can get twice as many PV panel watts on a solar controller at 24V versus 12V. It also allows for smaller wires/fuses/breakers/etc. if you are running a larger inverter. I weighed the pros and cons for the van and went 12V. Having a single voltage makes it much easier to cross-connect bits and bobs after a failure in the field.

You remind me of Nikola Tesla.
