NEDRA EV racers are mostly using lithium these days, though, since the price has come down. These are usually reserved for either AC drive systems, which use lead batteries more conservatively, or EV racers who are simply looking to pour as many amps into their electric motors for the quarter-mile as quickly as possible and don't care much about range. The "Lead Foot Factor" I just mentioned becomes a REAL issue with 12 volt batteries. but lightest weight of all the lead golf cart batteries.
Shorter range, unless you've got an AC drive system. And the 8 volt batteries can be drained faster by a lead foot than the 6 volt variety.Īnd the 12 volt golf cart batteries, you ask? Since lead is fuel, and it's heavy, it follows that less weight means less lead.and less lead means less miles. This is the cycle life of a battery, and in general, the cycle life of an 8 volt golf cart battery is shorter than that of a 6 volt golf cart battery. Amp hours are heavy, and deep-cyclable electrode plates are heavy since the amp hours in an 8 volt golf cart battery are about the same as their 6 volt counterparts (although see next item on the list!), this can only mean that the electrode plates are somewhat less sturdy.which means you can't charge and discharge them as many times as their six volt cousins before they refuse to recharge again. If you're pushing your weight limit already, this may be a consideration.ĭisadvantages of 8 volt golf cart battery. Fifteen 8v batteries weigh less than 20 6v golf cart batteries, overall. For example: Powering a 120 volt system means using 20 six volt batteries, or 15 eight volt batteries. Typical car-load of 8-volt golf cart batteries will weigh 1000-1200 pounds, rather than 1200-1600 pounds if you use the same overall voltage of 6-volt batteries. If you're operating on a shoestring, this might make the difference between getting your electric car on the road.or leaving it, nearly complete, littering up the garage and irritating the spouse. Advantages of the 8 volt golf cart over 6 volt.
