I recently installed an Epoch 460Ah battery. I had previously upgraded my converter/charger (50amp) to be lithium compatible (progressive industries I believe).
I charged the Epoch to 100% when I received it and before install. It has a bluetooth connection to a phone app, so you can read the SOC.
On our first trip out to Arizona, we stayed in locations (9 days) that all had a 50 amp service, so we were only on battery during transit (4 driving days, about 6 hours). During driving, only the WIFI and propane detector and brakes should have been the load on the battery. I also have 200 watts of solar on the roof.
The odd thing, is when I returned and parked the rig, I checked the battery and it was a 38% charge. I cannot understand this - left at 100%, was plugged in the whole time, and return with 38%. It was very cold (we were at the Grand Canyon for part of it) but plugged in to 50amp service.
My uniformed guess is that the battery voltage is/was higher than the converter voltage, so it ended up powering all the dc during the trip (heater mostly, and lights), and that the charger portion of the converter could not keep up the charge on the battery.
Any ideas? I installed the 460ah battery because we plan to do some boondocking this spring, but seems like I won't last long off the grid...
