![]() Since I think of my RV more as a "emergency vehicle" I wanted it to be at 100% all the time, so I bumped up the float voltage to 13.5. I had mine set up to float at 13.2, and vampire loads were causing the LFP house battery SOC to drop to under 80%. If you can find a happy compromise between Lead Acid and Lithhium profiles, the IP22 is great. you can't have different charge profiles for each battery. Automatic three-stage charging extends the life of your battery with output voltage modes of 13.2 V dc range float mode, a 13.6 V dc range absorption mode, and a 14.4 V dc range bulk. I have a 3-channel IP22 (of which I'm using 2: one for house LFP and one for lead acid starting battery) and it seems like it bonds the two together. The WF-8955 Power Center provides 55 amps and a clean, constant 13.6 V dc nominal output for the reliable operation of electronics and appliances. Second, note that the multi-battery IP22s do not have independent control of all circuits. Many LFP batteries are good for 2000+ cycles, and if you are storing your RV part of the year, you aren't even doing one cycle per day. I have a small RV with the IP22 (30 amp / 3 circuit).įirst, 50% SOC is very conservative - your LiFePO batteries will probably already last 10x longer than your RV, even if charged to 90% or 100%. The 12v appliances include: (They turn on and off as needed.). ![]()
