Please let me know if there is already a post that covers the subject, although I’ve been searching.
5th wheel trailer has 400ah of 12v lead acid with 300w of solar. System works great. But a few days of camping with no sun or lots of trees requires some recharging. I have a portable generator but also have a 200ah 12v lithium portable power station.
What’s the best way I dump the power from my Lithium power station into my lead acid battery bank.
1) I know I can use an inverter and battery charger from the power station, maybe 80% efficient..
2) direct connect the batteries, This probably would work until the batteries are even.
3) how about a 12-24v boost converter to MPPT. Seems about 90% efficient.
4) dc to dc charger, but I don’t have an alternator connection that they seem to need.
Think of it as this. Trailer is in a remote area. I take the power station to town or to sunny location charge it up and then dump it al the powerl in my lead acid back at camp. Like going to town to fill a gas can.
Any suggestions are appreciated.
