Hi all,
I am wondering about how to handle my travel trailer batteries while in tow. When home I use a small charger/maintainer to keep the TT batteries (2 6v deep cycle) topped off. When I get to camping, I plug in my Renogy solar suitcase to get solar charging. its only 100w so depending on how long I camp and how much I use while doing so, the batteries can get run down. The standard 7pin connection from my vehicle "charges" the batteries while traveling. The TT batteries seems to do fine however I believe its ruining my truck battery, since once the low battery from the trailer is seen by the trucks alternator it boosts up the voltage to charge. I believe it's over charging my truck battery due to the lower voltage of the trailer batteries. So what do you all do? somehow disconnect the trailer batteries from the vehicle? its not straight forward, as the trailer batteries are required to be connected for at least the emergency brake-away system and to run the refrigerator etc. while in transit. Eventually I'll get more panels to keep the batteries charged but I assume this is a problem for others as well. I am going to be converting over to a LifePo4 battery in the near future so it will be a question on how to maintain it then also.
Thanks!
