My cart batteries are LiTime that I got from Amazon. The 48 volt 100 amp battery with a charger was around 1200. There are some cheaper ones that you can buy. I would suspect that tariffs are going to be hitting these batteries come January.
All the labor of man is for his mouth, and yet the appetite is not filled.
So, I have a JD Electric Turf Gator (2000-2002 I think) bought it used years ago, it runs on 8-6v’s for 48v. Use it around the house, what is the recommended lithium battery for it? Don’t need 25 miles, doesn’t have 4wd, ride down the road to visit a friend
Bamachem - is your shop the golf cart place on Morphy Ave? Have you ever done a tracker EViS?
No we are Make Wake Marine - boat dealer in Barnwell on 98. We did the first Allied Commercial LiFEPO4 swap on a Polaris Ranger EV in the country - my personal one. Amazing setup. We sell their commercial series batteries for boat trolling motors and cart swaps.
So, what’s the disadvantages of doing a couple smaller cells let’s say 3-4 65amh?
For maximum battery life you need to disconnect the batteries and rotate their position in the array on a regular basis because they won't self-balance. With a single commercial-grade unit, the unit self-balances and there is literally zero maintenance.
Just got a Polaris Ranger EV in for a swap. I'll post pics if yall want. Doing a single 105AH setup with new charger, removing the old Polaris charger and doing the bypass jumper so the cart will still run, and adding a COM port state of charge meter to the dash. About $4350 out the door, and it's done right with a 10 year warranty on the battery.

Kinda confused, with multiple units you need to swap batteries for shelf life, one battery good to go so, how does the 2 battery system work in your EV without out swapping batteries? You can’t put them in parallel is what I’m asking I think.
Most LiFEPO4 conversions use battery cells about the same size as their lead-acid counterparts. You install 6 or 8 of them in parallel (lead-acid are usually lower voltage and in series). When used in a high-current situation like powering an electric motor with high inrush currents, the battery cell closest to the motor will deplete faster than the one at the end of the parallel circuit. Because balancing the voltage and remaining AH in the batteries isn't instant and there isn't a Battery Monitoring System in place to balance the cells, the one closest to the motor (via the wiring run) will need to be eventually moved to a postion where it will see less depletion in order to have the same lifespan as the other batteries. The Allied Commercial cells I'm talking about are basically 4 normal sized battery packs in one big sealed waterproof box with an onboard BMS system that monitors each individual LiFEPO4 cell and will balance them as needed. With only two cells in parallel and wired the way we set them up, they have equal draw when in use. You can also turn them off, so you can use one cell while the other is "off" and can later be used as backup or reserve. You have a pair of gauges on the dash that shows the state of charge on each cell, and you can download an app on your phone and connect via bluetooth to each one to view trouble codes, status of charge, and even look at each individual battery voltage, etc in the cell.
