That would have been all fine and well – exactly as the system was designed to do.īut the way our system is designed – the EMS does not automatically reset once power comes back on.
While the power was out, the fridge drained the batteries to the cut-off point of 11.2 volts, triggering the battery management system to automatically pull the plug to save the pack. Well, nearly a year later the storage unit suffered an extended power outage, likely caused by a storm.Īnd because Zephyr was indoors her solar panels weren’t overly useful in helping out with the situation (ok, not useful at all). So we opted to not fully shut down and clean out the fridge, figuring we’d have power to keep it going, and we’d back in a few months. We were both pretty darn sick when we pulled into that storage unit, with a long drive back to Florida ahead of us. The storage unit was enclosed, with a basic 120V wall outlet power hook-up. Lessons Learned After Long Term RV Storage - Getting Zephyr Back on the Road We shared some of our long term storage mistakes in this post: One thing lead to another ( Sanford), and we didn’t end up returning to Zephyr until October 2019. In March 2018 we left Zephyr in storage in Texas while we pursued our boating season, intending to return back that fall.

Since there were limited commercial options and resources available to tap into, we decided to build our own battery bank out of cells meant for electric vehicle conversions. Specifically - we went with Lithium Iron Phosphate aka LFP aka LiFePO4.Īt the time, while a few people had done installs on boats in the cruising community, there were very few RVs with lithium based house system. The just emerging lithium ion battery options had already been on our radar, and since we had the opportunity to build our bus’s electrical system from scratch - we decided to delve into the world of lithium. In June 2011, we bought our vintage bus conversion without a working house battery system installed in it. In this post we’ll recap our history with our bank, share what we think happened and what we replaced the dead batteries with.īrief Recap of Building our Lithium System Those batteries have served us well for years, but unfortunately – they died while Zephyr was in storage for nearly a year and a half in 2018-2019. We originally installed our GBS lithium cells back in August 2011 – and as far as we can tell, we were amongst the first motorhomes to have a lithium house battery system, and we were certainly one of the first to share publicly about our project. In what seems like another world now, last December we replaced our dead lithium batteries in our vintage bus, Zephyr.
