This is the Traxxas Power Cell 7.4V 2200mAh 25C 2S 2-Cell LiPo Battery with iD connector for Traxxas 1/16 vehicles. The Traxxas 2820X 2-Cell battery will work with the Traxxas 1/16 E-Revo, Slash, Summit, and Rally vehicles. It can be used in both brushed and VXL brushless models, and offers a significant increase in run-time over the stock NiMH battery. 

This battery has the Traxxas iD connector.  You must have a LiPo charger equipped with iD connector (like the Traxxas EZ-Peak iD charger) or a LiPo charger and the Traxxas 2938 LiPo charge adapter.

1/16 E-Revo (brushed & VXL Brushless) 
1/16 Slash
1/16 Summit VXL
1/16 Rally

Traxxas’ 2200mAh Power Cell LiPo packs are ideal for all 1/16 brushless VXL models. Power Cell LiPo packs are engineered to give the punch and on-demand power to reach the top speeds Traxxas models are built to achieve. Premium LiPo cells developed specifically for Traxxas feature oversized discharge tabs for maximum efficiency. The cells are hard-wired with 12-gauge Maxx Cable, eliminating the resistance and power-loss associated with plug-in wires. The packs’ semi-rigid construction results in a firm, rugged, and compact pack that does not require a hard case, and the center-wire configuration assures a pinch-free fit in Traxxas vehicles. 


  • Semi rigid construction does not require a hard case and eliminates wire harness connectors that can loosen and fail.
  • Engineered specifically to fit Traxxas models.
  • 16AWG multi strand wire is soldered directly to the LiPo cells eliminating increased resistance from bullet connectors and accidental reversed polarity connections.

Can I link 2 x 2820X batteries like you can the 2925X batteries as the 3063X battery connector says it’s not compatible. Kind regards Ian
Asked by Ian Read on 21st April 2021

In theory, yes - however you'd need to modify the link cable as the connectors won't work with LiPo batteries

Yes that would fit

Answered by: Ben @ Wheelspin Models

Whats the runtime with one of these compared to the nimh one you get with the e revo 1/16?
Asked by Rob on 3rd October 2021

I would say you should get about 20 mins run time maybe a little longer if not on the throttle too much
