Costco vs Sams Club 6V Golf Cart Batteries
Hi, I'm about to buy two new 6V golf cart batteries for my TT. I am choosing between the Costco and the Sams Club 6V batteries. Here is all the stats provided for each battery where I live: Co...

Most of the older RV "converters" were of ferroresonant design. A transformer, relay, capacitors. When the capacitors aged, the voltage creeps up. If you doubt this, get ahold of an old converter. Connect a 5,000 uf electrolytic capacitor to the output and see what the voltage does. Surprise! it climbs. Just adding a 2nd battery caused the voltage to go up, a 3rd battery, WOW!
But placed on a timer, these critters make an inexpensive (free) battery charger that can be tamed with a mechanical timer, and tuned by adding (or subtracting) capacitance. Limit the battery charging amperage potential by using small charge lead wires (trial and error - start off with 14 gauge). Connected directly to a battery these things can over-amp. They used a huge BLEED RESISTOR to shunt power to charge the battery. Normally these critters were BATTERY SUBSTITUTES. The relay switched the converter in and out isolating the battery when the converter took over duty of powering up the 12 volt system.
