CodyVerified owneron Traxxas EZ-Peak Live 4S "Completer Pack" Multi-Chemistry Battery Charger

Bought this for my Xmaxx and the batteries are ok but I’m not very impressed with the charger. When I plug it in sometimes none of the lights come on and it does not respond in anyway until you un plug and try again. It does charge pretty quickly and is really easy to use when it works but If I were to do it again I’d go with a different set up.

Good match for the Xmaxx. Like the Bluetooth connection with the app to monitor the batteries individual cell charge. I'm sure there's better batts and chargers but this is good to start with and last for a while..

What reviewers say

Reviewers generally praise the charger's speed, ease of use and the smartphone app, which shows per-cell voltage, current and estimated time remaining. The two included 6700mAh batteries are described as performing well with the Xmaxx and XRT, and several reviewers note they balance well. The main recurring problem is intermittent power or response failure, where lights do not come on until the unit is unplugged and retried, with one reviewer reporting the problem worsened after a few months. One reviewer also wished for better strain relief where wires enter the battery, and one criticised the price and the charger's compatibility limited to Traxxas products. One low-rated review describes a charger that stopped reading balance leads, though it is not clear this was a common fault.

  • + Fast charging
  • + Easy to use
  • + Phone app with per-cell monitoring
  • + Batteries balance well
  • − Intermittent power or lights failure
  • − Wire strain relief on batteries
  • − High price for Traxxas brand
  • − Charger may not read balance leads
