LiPo Battery

Lithium polymer cells hold more energy per gram than NiMH and discharge it at a steadier voltage through a shot string, which keeps rate of fire consistent from the first shot to the last rather than sagging as the pack drains.

They demand real care in return: over-discharging, puncturing or charging an unbalanced pack can cause a fire, so every LiPo needs a dedicated balance charger and a fireproof storage bag when not in use. Capacity is rated in mAh and discharge capability in C-rating — both printed on the pack and both worth checking against what the gearbox actually needs.

Storage voltage matters as much as charge cycles for pack lifespan: leaving a LiPo fully charged for weeks between games degrades it faster than storing it at the roughly 50% "storage charge" most balance chargers offer as a dedicated mode.
