When the lead acid batteries in my Polaris Ranger EV wire out, I spent a little extra money to convey to lithium batteries. 500 lbs. lighter!, no watering ever. Should last 4x longer as well. With lithium, you can use all the rated capacity without damaging the battery; lead acid batteries are permanently wounded by discharging past about ½ of their rated capability. Deep-discharge lead acid batteries can handle that better, still not as well as lithium batteries.

In my case, the lithium batteries were almost direct drop in, the only change I made was to the wiring and adding the charger that came with the batteries. I left the original charger wired into the EV (except to charging the lithiums) ,to avoid having to make other writing changes.
El Hefe has a three year old HuntVe with 93 miles on it. He admits he never charged it correctly and I bet he never watered the batteries either. Now the batteries are toast with several of them having split cases. Now he wants new batteries. I'm going to try and push him toward lithium's. Because it's 1300 bucks for another set of FLAs. At this rate, the Lithium's will pay back in no time. B.
