I just replaced my AGM start battery on my 2022 Interstate 19 with an Antigravity LifePO4 lithium battery. Do I need to bypass the Victron DC to DC gfactory installed buck booster or do I need to reprogram it with new settings via its USB port. If so, what settings should I change.? The new start battery has a built in BMS. The correct configuration is causing the Start battery to drain below 12 volts. Many thanks. See attached wiring diagram. Let me know if the wiring needs to be changed.
I just replaced my AGM start battery on my 2022 Interstate 19 with an Antigravity LifePO4 lithium battery. I have coach batteries which are 100 amp LifePO4’s. Without making any changes to the wiring or the Victron TS-800, when the RV is not connected to the grid the coach batteries drop from 13.6 to 11.5 volts within a few hours. I have both a solar controller and batter charger connected to the input of the DC to DC converter. Many thanks. See attached wiring diagram any photos. Let me know if the wiring needs to be changed.
