Battery Replacement Advice Requested
Posted on 3/20/25 at 4:44 pm
Posted on 3/20/25 at 4:44 pm
My background is IT, hence my username. :)
I have a 2021 JD Electric Gator (TE). It's Lead Acid batteries have gone bad.
I would like to replace them with Lithium Ion.
I can't confirm, but it appears that the Gator requires peak amperage of 400A. How can I go about confirming this? Hard to get wiring diagrams and I have had virtually no success searching the net.
Anyone else attempt this type of conversion?
Any advice would be appreciated.
TIA

Have you tried calling your local JD dealership? They have always been helpful from my past experience.
Seems like you should be able to obtain some sort of service manual online with the make/model.

Thanks for the response.
I have spoken to my local dealership. They will not do the conversion.
They indicated that they don't see many electric gators and that he couldn't help me.
I was certainly disappointed in that response.

I assume it has a built-in charging system? The battery replacement itself should be simple if they are 12-volt batteries tied together in series and/or parallel.
The Charging circuit will be the rub. if they have a board-level charging system that is part of the overall control circuitry, it may be more difficult to untangle. If it has a separate charger, it may be suited for lithium batteries or you could just use an external charger that is set up to charge Lithium batteries.
Pictures might help.

Start here:

Then there is also Perplexity.AI to ask the question for additional information.

Thanks guys. Much appreciated.
I think I'll give it a try. :)

Why not just match or exceed the cold cranking amps (CCA) rating of your current battery? Your current battery’s CCA rating should be written on the label.
FWIW, I really don’t see the point in converting to Lithium ion battery in something like a vehicle where weight is not a big deal…but that is not what you asked.

Spankum,
My reasons are that Lithium Ion batteries:
1. Last longer
2. Are lighter
3. Require less maintenance
4. Cost less
5. Perform better than Lead Acid

None of that is really relevant with a lawnmower. The cheaper and better option would be a replacement lead acid battery and a good single bank charger/maintainer.
As stated, charging is the problem and isn't easily modified on most small engines. It'll be far more expensive than it is worth.
Eta: nevermind, i am dumb.

Right - It's a Gator TE (Total Electric). No engine, just a motor.

Check out battery hookup or green tech auto. I guess you’d want 3-6kwh 13s in the $200-500 range plus $100 bms/solenoid plus $15-150 charger. Really just depends on what you do with it. It’d be hard to burn up 1kwh trolling around the block or to your deer stand, but you may have a huge ranch or want to add a big inverter for power tools and such. Lithium is a no-brainer. Way smaller and lighter for the same capacity. I doubt you need more than 200a output and a 48v/13s pack in the 3-6 kWh range would likely be capable of 1000+ so no worries there.
Here is a killer 14s 10 kWh pack for $500. Only 300a but that’ll work. Not sure if fits.
LINK
Here’s a 12s 5 kWh for $250. That was just from less than a minute of looking. I’d try to stick to 13s if possible but these work too.
LINK
Here’s the 13s pack I purchased over a year ago for a DIY cart and I love it. Surprised it’s still available. 3kwh $200. Easy to modify.
LINK
Here are the first 13s packs I ever used. Super high quality. Not super dense but very high power. You can get 10 for $150 to make 3 kWh and fit any shape. You’d just need a lot of wire and solder to fit the BMS. These were unavailable for a year or I never would have considered anything else. I’m actually ordering three more just because I see they’re available again.

Just kidding, kinda.
