Battery Guide

Every Team EAM Graph-X pack side by side: cells, size, weight and what each one is built for. Tap a pack name to shop it.

Choosing the right pack
  • Check the length first. Full-size 2S packs are 139mm, Shorty packs are 96mm and the Mid-Shorty is 113mm. Your chassis decides which fits.
  • Height matters on low-CG cars. Lower packs (16.5–19.5mm) keep the center of gravity down; taller packs fit more capacity.
  • Check your class rules. Some classes cap pack weight or require ROAR-legal packs. Each product page lists its ROAR/EFRA status.
  • HV packs (7.6V) are marked below. Make sure your charger and class allow HV.
