I am building up my new rig and installed a 300ah/12volt LiFePo4 battery first. While waiting delivery of the mounting hardware I went on a camping trip and by mistake left a 12volt light on in the camper. When I came back the Victron shunt said the battery was at 4%. (Did I do it any harm?) I plugged into my house to recharge and according to the shunt the battery was taking in 50amps. I'm plugged into a 15amp plug, so I assume 50amps @12volts is only drawing 5amps on the 120volts circuit. Is that right? The camper I used to go camping is also set up with a LifePo4 100a/h battery. Over the course of the 2 weeks I run that down to 40%. When I plugged that in it would only take 10amps indicated on the shunt. The bigger unit is using a WFCO lithium converters, the smaller is using a Progressive Dynamics Lithium converter. Is it a battery size issue or a converter issue. Maybe my smaller camper's converter really isn't Lithium as much as it could be. It does charge to 14.6. Any ideas?
