Description
17+ is our new battery for your Ranger EV
With a 17+ you can ride all day, work hard, track game or go on that long mission.
You get an astounding 70 miles off-road and 85 miles on hard surfaces. Your Ranger EV uses a lot of energy. 4 to 5ah per mile is normal.
Need more? Two 17+ batteries (35kWh) will fit in your Ranger EV.
The 17+ evolved from our 14.4kWh battery introduced in 2022.
The 14.4 (280ah) grew into our 15.6 (304ah).
Now, capacity has increased again to 17.1 kWh (334ah).
The 17+ is built with EVE LF334 cells rated at 3C (1,000 amps) intermittent and 1C continuous discharge. Useable cell capacity averages 348ah. The cell spec is on our support page.
Trail tested. Watch Sparky, our 2015 Ranger EV run with a couple of RZRs.
