The Traxxas Spartan boat ships with two 5000mAh 3S LiPo packs and is designed to run on two 3S (or 6S) batteries for its rated 50mph top speed. Note that current Traxxas vehicles use the proprietary Traxxas iD connector system — official Traxxas Power Cell packs plug straight in, while third-party batteries need an iD-compatible connector or an adapter.

Buying tips
- Traxxas vehicles use a proprietary iD connector — check whether a third-party battery includes it before buying, or you’ll need a separate adapter.
- Run two 3S packs (not one) to hit the Spartan’s rated 50mph top speed, per Traxxas’s own spec.
- Always use a LiPo-specific balance charger (like the EZ-Peak Plus) — never charge LiPo packs on a basic NiMH charger.
