Hey all,
I'd like to do some boondocking in my toy hauler trailer next month for a trip to Utah I have planned already, but I've still got a ways to go on my solar build.
So here's what I'm thinking so I don't have to be running off of my generator 24/7.
My toy hauler came with a factory installed ONAN QG 5500 generator and 2 lead-acid batteries. Obviously these batteries wouldn't last long under load (laptop's, my internet setup, residential fridge).
I already have 16 280-Ah LiFePo4 batteries (14.3kwh total) that would help immensely. So I would remove the current lead-acid batteries, install my LiFePo4 batteries, only use the generator to charge up the batteries, and then I would only need to run the generator when the batteries became too low to charge it back up again. I can even set the generator to auto start when the batteries reach specific (somewhat user selectable) voltages.
I already have a Batrium BMS, the toy hauler already has some type of converter since I can currently charge the factory lead-acid batteries with the generator.
Am I missing anything or is this really as simple as installing my batteries and BMS and removing the lead-acid batteries? (of course configuring the BMS etc)
I shouldn't need to buy anything extra at this time and would make this trip MUCH better.
The boondocking portion of the trip would probably only be about 5-7 days.
