Duratrax 7.4V LiPo Car Battery Packs

Duratrax 3700 7.4V LiPo Car Battery Pack

With some of the newer RC cars on the market, even sport drivers are now moving over to LiPo batteries to handle the powerful brushless motors like on the Traxxas Rustler VXL. The new LiPo batteries are generally lighter and much more powerful than the comparable NiCd and NiMH batteries. A note here is to make sure your motor is capable of handling these batteries and you should check with your manufacturer before using. LiPo allow motors to draw more amps quicker and this also generates more heat and of course power and speed for your car or buggy. So use as recommended.

With that said, Duratrax has two battery packs available which may suit your needs. They have a 3700 model which stands for 3700mAh at 7.4V which has a max charge rate of 3.7A. Also, they have a 5400 model which is rated at 5400 mAh at 7.4V and a max charge rate of 5.4A. Both packs are built securely with impact and puncture-resistant ABS case. This is important becuase of the special handling that is needed with LiPo packs which may catch fire when damaged. You should read all safety instructions before using to make sure you understand how to discharge and charge your battery packs. In addition, the battery packs come with gold-bullet connectors for the terminals and have standard connectors. Other connectors are available as well such as Deans or Traxxas style connectors.

Duratrax's website also recommends a quality charger such as the Onyx 230 or the Intellipeak ICE that are specially made for LiPo batteries. In addition, you will need a balancer for these packs which make sure each cell is conditioned properly. Duratrax recommends the Team Checkpoint Pro Balancer.
