I have a Traxxas id charger. I inherited some Lipos with “universal” connectors. Can I use them with my id charger? They plug in fine.

Universal connectors and adapters will allow non-traxxas batteries to plug into a Traxxas id charger, but the id battery-identification system will not be able to determine whether the pack is a NIMH or Lipo, its capacity, or its voltage. If you have an Ez-peak Live charger, you must use the Ez-peak Live app to specify the pack is a Lipo and input the cell count, capacity, and charge rate before the charger will allow you to charge a non-id pack. For the Ez-peak id and Dual id chargers without Bluetooth, you must press and hold the Start/stop and Charge Rate buttons together to enter Advanced mode, which will let you select NIMH or Lipo and set the charge rate. These safeguards go a long way to preventing mix-ups, but it’s still your responsibility to make sure you choose the right settings, particularly the battery type. ALWAYS double-check to be sure the correct charge mode is selected, especially when charging a Lipo.

An important safeguard built into the physical design of the latest Traxxas connectors is NOT present with universal or “Traxxas compatible” connectors. If you try to plug a Traxxas id Lipo into a Traxxas Nimh-only charger, the connector will not fit. Charging a Lipo pack with a NIMH charger (or the NIMH mode of a multiuse charger) will, at the very least, ruin the battery. If left to continue charging more than a few minutes as a NIMH, a Lipo will catch fire. That’s why we (and all battery makers) always say:

Traxxas id chargers can charge non-id batteries, but you’ll need to program the settings yourself.

ALWAYS confirm battery type before charging. To prevent mix-ups, Traxxas id Lipo packs have a unique connector that will not fit into Traxxas Nimhonly chargers.

NEVER leave a battery unattended while charging.NEVER charge a Lipo battery using a NIMH charger or charge mode.
