Just an FYI

[suprz]

I am getting a Batteryminder charger to keep my RV chassis battery charged. I am going to use the ring terminals to attach the wires to the battery permanently. I have a storage bay on the same side as the battery with a 120volt outlet that I want to put the charger to leave it plugged in. My thoughts are that while at the Rv park, the charger will keep the battery charged like it would at home. I contacted Batteryminder tech support and the model I chose (#12117) will draw 20-30 milliamps if attached to the battery without shore power. The tech support also said that if the charger is connected and no shore power is on, with the engine running and charging the battery, it won't hurt the charger. So just some info for you guys

I'd still rather not parallel my AGM house batts with my Flooded engine batt for long term floating. No evidence it would be bad; just don't like to.

OP could change one of those ring terminals for a clamp to disconnect when desired.

X2. better chiice, IMO. no external power needed.

That is kinda neat... Does same thing one of my expensive relays does haha... Steals alittle power here and alittle power there...

I did same thing here but used one of those small 10WATT solar panels sitting in my windshield area. Put a 12V plug on it and plugged into an always live 12V socket in the truck. Does a great job keeping my truck start battery a trickle charge.

The solar panel is cheap around $20 from local auto parts store...

This way I didn't have to worry about finding 120VAC somewhere to plug into it. Always sunlight during the day... Even cloudy days it is usually still putting in a small charge...

I got this idea from my battery bank replacement ongoing project. I'm going to use a TORKLIFT slide on lid battery box and it came with a one solar panel for the lid. Since my battery bank has two groups of GC2 6V batteries I am going to order a second solar panel and then each group 6V batteries in series will always be getting a 12V small trickle charge... The slide on panel already had the mounting holes punched in on both sides...
