If your new battery pack has a female XT-60 connector on it but your vehicle doesn't, use our XT-60 Motor & Battery Connector Adapters to bridge the gap and allow you to run your new packs. We have four different adapters that feature an XT-60 Male plug on one end, and the following options for the other end: T-Plug style Female (#C29033), Tamiya-style Female (#C29034), EC3-style Female (#C29035), or Traxxas-style Female (#C29036). The XT-60 Motor & Battery Connector Adapters are sold individually.
