Polaris Ranger Lithium Battery Conversion

We were able to revive three of the eight batteries that came with the Ranger, but we need four to move. So we’ve removed all of the lead acid batteries & cleaned up the trays. Battery acid isn’t great for a steel plate — baking soda water to neutralize it, then a scrub.

As a proof of concept, we’ve got the 48v lithium battery in the bed and will temporarily wire it into the vehicle. It’s wild that the one orange battery has about as much usable power as four of the red ones. Weighs about the same, takes up slightly more space but not that much.

Lisa challenge.

I hereby challenge Lisa J Rushworth to continue not posting about computer stuff for 2 more weeks. Any breach of this policy shall have the effect of having hazelnuts tossed at her (5 Hazelnuts per violation). In addition, she shall, for each post, receive 1 more week of anti computer posting. “Computer stuff” shall be defined as in previous challenges.

And she, as I am the one posting this, is not going to comment on the weather or such in such an important, OFFICIAL post.

Polaris Ranger EV Dash Indicator Lights

We lost a few lights on the dash of our Ranger – and the parts diagram shows it as one monolithic (and ninety dollar!) part. That’s … more than I want to spend to find out I’m in forward mode!

Looking at the back of the unit, though, there’s little slotted buttons — like a bulb that can be removed. And, yeah, thereĀ are bulbs in this thing. Six of them. Which you can buy at NAPA for about a buck a piece ($5 for a 5-pack). Or replace with LEDs for under $0.40 each (and you’ve got spares for the future). For this specific LED replacement, the negative side goes up when you install them.
