Got a question? We can help.
These are the questions we hear most. If yours isn't here, contact our team.

Talk to our lithium specialists at Inverters R Us.
Will this kit fit my vehicle?
It's built for the Polaris Ranger EV and Bad Boy Buggies. For other carts, send us the make, model and year and we'll check fit.
How long does install take?
Most owners finish in 2–4 hours with basic hand tools. Lithium Rhino provides install videos and phone support if you get stuck.
Do I need a new charger?
Yes, and it's included. Lead-acid chargers use the wrong profile for LiFePO4, so use the lithium smart charger that comes in the kit.
What do I do with my old lead-acid batteries?
Most battery shops and scrap yards take them, and many pay scrap value.
How does it ship?
The kit ships in a reinforced crate, and tracking is emailed once it's on the truck.
