sell the electric car and get a gas car
problem solved
batteries every few years, you will hate it the 2nd time you have to put batteries in
if (when) the controller dies you will hate it
if (when) the motor dies, you will hate it
when a battery shorts internally, and explodes, you won't hate it. You will despise it assuming you survive if you are on it when it goes boom
The last example is what happened to me. BIG explosion and have lifetime health issues because of it (burns on face, neck, back, permanent hearing loss)
if you have 6 batteries you have 12 terminals that you need to keep squeaky clean. Many cables to keep up with (zero corrosion). Of course you have to stay on top of the batteries too, maintenance items and you will replace them every about 5 years if you are good about charging and not overcharging them. That is assuming the charger works properly. The frame/holder under all the batteries tends to rust out. The frame rusts out. Then you're back to fabricating a new frame/holder, unless yours is plastic (some of them are).
replace the batteries with what they manfacturer of the charger recommends; sometimes changing brands can cause issues (charger is considered specific). Seen quite a few guys say I ain't paying your high price for batteries and they go buy their own from wherever and the charger overcharges them, or doesn't charge them at all in one case so you have to be mindful there too.
everything about electric golf cars *****
seen many cause trailer fires in race car trailers, seat comes off while bouncing around in the trailer and shorts a pair of batteries, causes fire, takes out tens or hundreds of thousands of dollars worth of uninsured race car stuff. I know of 4 for sure, many more "heard of". I know high end pro's that won't use an electric cart for this reason
