The RC7-GS inverter charger can properly charge 105Ah AGM batteries using the 125Ah setting, as AGM charging is voltage-based, not capacity-dependent. Generator start issues typically stem from wiring problems or incorrect DIP switch configurations.
Master your RV electrical system from house batteries to shore power. Covers 12V DC, 120V AC, inverters, and charging.
Troubleshoot house batteries dying while on 50 amp shore power. Diagnose converter, breakers, and connections to restore proper charging.
Even with disconnect switches engaged, phantom loads and battery self-discharge can drain RV batteries during storage. Installing battery maintainers, using master disconnect switches, and addressing phantom loads will solve this issue.
LiFePO4 lithium batteries like the Dyness can replace lead acid batteries, but you'll likely need to upgrade your converter/charger to a lithium-compatible model. The BMS protects the battery from overcharging and provides longer life with faster charging.
A lithium battery manager relay protects lithium batteries from overcharging by disconnecting them from the alternator when not needed. Installation involves wiring the relay between your alternator/converter and battery bank with proper fusing and control circuits.
Boiling battery with sulfur smell means severe overcharging or internal short. Disconnect immediately - hydrogen gas is explosive. Battery must be replaced. Check converter/charger output voltage before installing new battery to prevent recurrence.
Yes, you can use a spare DC/DC charger to maintain chassis batteries during winter storage by connecting it between your solar-charged house batteries and chassis batteries. This creates an effective battery maintenance system for long-term parking.
Your Renogy lithium batteries showing different charge percentages indicates a communication or cell balancing issue. Check wiring connections, perform a manual balance cycle, and consider firmware updates through Renogy's app.
Your Class A RV tripping the GFCI every couple days, especially on hot days, is likely caused by your solar inverter developing ground faults as it heats up, though a failing battery could also contribute to the issue.
Two batteries using more water indicates failing cells or connection issues. Check terminal tightness, measure voltage during charging on each battery, and test specific gravity. Higher voltage on some batteries indicates internal resistance. May be warranty issue at 6 months old.
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.
