Greetings beloved comrades,
I recently acquired a 36v golf cart that has 6 6v batteries in series. The existing 12v accessories, mainly lights, are powered by a separate series connection to 2 of the 6v batteries.
I don't like tapping only 2 of the batteries, since prolonged usage will imbalance the batteries and possibly require individual charging.
My question is: Can I wire 3 12v circuits in parallel from the 6 batteries for an always active supply, or would it be better to add a separate switched 36v circuit and a buck converter to get 12v?
I would prefer the first solution just to avoid buying a chunky switch and converter, but if the latter is better is for efficiency/battery life, I'll go that direction.
