Ionic Batteries & Support

While others choose to purchase multiple batteries every two to three years, I was fortunate to find Ionic batteries early on. Own five and best purchase ever made. Thanks for the support!

12v 4A charger.

Charger works great. Pretty straightforward unit. Nothing fancy here just what you need to get it done. Comes with a few different connection options which is nice. Also most importantly a reasonable price that's affordable.
