Yo, LJD and others, I know LJD has more experience then myself in the use of and charging Golf Cart Batteries so Im looking for experienced opinions. I have a new used RV and will be running four 6 volt Deep Cycle Flooded Golf Cart Batteries in series/paralell for my 12 volt coach power (lights, vent fans, inverter, etc). The RV has the run of the mill cheap not well regulated approx 30 amp 12 VAC/12 VDC Converter Charger WHICH I DONT WANT ANYWHERE NEAR MY NEW GOLF CART BATTERIES (it can overcharge and cook them).
I will be using a Xantrex Truecharge 2 40 amp smart three stage (Bulk/Absorption/Float plus Equalize when needed) regulated charger WHICH I WILL USE TO CHARGE AND MAINTAIN my batteries.
Of course, when I'm plugged into shore power I can use the cheapie converter/charger to power my internal 12 volt loads (Still NOT to charge my new golf cart batteries, ONLY the Xantrex will do that) buttttttttt that darn converter/charger is a noisy buzzing heat producing piece of crap.. Sooooooooooo if instead I keep all my 12 volt loads on the golf cart batteries 24/7 (NOT use the converter/charger at all) and all the time let the Xantrex keep them charged and floating as it automatically determines they need it, IS THAT GOING TO HARM THE LONGEVITY OF MY NEW BATTERIES.
For best battery life you think its best to keep the Xantrex on them 24/7 and use them to power my RV 12 volt loads all the time or use the buzzing cheapie converter/charger to power the RV (although the Xantrex will still be on them all the time I reckon, even if Im parked in an RV park for months at a time??)
My buddy has a Xantrex he keeps on his batteries all the time and if he looks at the charge monitor its just setting there in float maintenance mode but when he switches on lights and fans etc in the RV it jumps up to a few amps and his batteries are already 7 years old n still okay.
We do some extended dry camping in Utah and Colorado which is why I can carry up to 100 gallons of fresh water,,,,,,run 4 Golf Cart Batteries,,,,,,going to install 200 watt solar panel on the roof,,,,,of course an Onan 4KW if needed
My MAIN GOAL is to maximize the life of my golf cart batteries so whatcha think ????????
PS any idea how often I should run the Equalize procedure?? I havent read all the Xantrex instructions yet
