A lithium battery showing 20% but not accepting charge typically indicates a BMS protection mode activation. Try disconnecting all power sources for 30 minutes, then reconnect to reset the BMS before checking connections and charging sources.
RV batteries draining overnight typically indicate a parasitic drain from components staying powered when they shouldn't. Use a multimeter to test each circuit systematically, starting with the main disconnect and working through individual fuses to isolate the problem circuit.
Dual purpose lithium batteries work for coach use but dedicated deep cycle lithium is better for house banks. Dual purpose compromises between starting and cycling. For RV house batteries, deep cycle LiFePO4 provides better value and cycle life.
Sawtooth patterns in Victron MPPT readings are often normal during float charging. The controller pulses current to maintain voltage. Check if battery is charging properly - if so, patterns are normal.
Beyond batteries: verify converter is lithium-compatible, add DC-DC charger for alternator charging. Choose LiFePO4 batteries with built-in BMS. Check if 2023 GT7 has lithium-ready charging system - some newer models do.
V10 lower hose replacement straightforward with coolant drain. Use quality hose and new clamps. Bleed air by running with heater on high.
Common RV components with red lights include LP detector, CO detector, surge protector, and inverter. Red typically indicates fault or alarm. Check for model numbers to identify and post photo for specific help.
Yes, you can likely replace your 2018 Georgetown's original lead acid house batteries with lithium, but you'll need to check your converter's charging profile and possibly upgrade it. Most 2018 Georgetown models came with converters that may not have lithium-compatible charging algorithms.
