Good catch on the inverter on! Would you know how to fix battery disconnect switch? We have the Firefly digital panel. I can turn my lithium batteries off, everything turns off in coach including smoke detector and CO detector, so nothing drawing power other than the battery itself and the firefly digital display.
Sorry Catu, I am not familiar with the Firefly panel. If it was my panel I would first pull the panel and connect across the terminals on the batt switch to test the switch. Then i would check the solenoid that actually disconnects the battery. Again adding power to the right connection there and it should fire and complete the circuit.
I ran my AC on my battery for 20 minutes for a test The charge went down to 11.75 What is the lowest I can go too on my charger? Started hearing a beeping noise. I have the Under hood generator I live in my Roadtrek full time and have a pet. But worry about leaving for to long in the RV in August
50% discharge on an Agm battery is about 12.1 volts. From there down to 11.6v will shorten your battery life. Below 11. 3 v you are causing permanent damage.
It's the private label roadtrek inverter charger that came with the unit. It's actually a powerstar lw but they are not so easy to find. I had battle born check it out and it just took a little tweak to make it work for the lithiums. Battle born has a inverter charger made by aims they recommend if you don't have one. I also have the complete install video here. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-t7VkKfU8KTk.html
Well, Thats the beauty of lithium's you can run them completely down without the damage you will get with Agm's . That said, even lithiums prefer to be kept above 50% to give you the most life cycles. Since I drive every day when out in the Roadtrek, my engine is charging them back up. A night of use will only use about 30% of what they have to offer so I suppose to answer your question about 30 % depleted. If i have a park I do plug in and turn on the inverter so its charging them. The battle born's will shut off when full and honestly I don't even have to think about them. It's been 8 months now and still are flawless!
It's the Roadtrek label that came with the van which is actually a Power star LW from china. I only had to make an adjustment on the settings recommended by Battle Born.
