Chargers

Battery chargers aren't a one-size-fits-all category in airsoft. LiPo batteries need balance charging — every cell in the pack must reach the same voltage at end-of-charge, which requires a charger that monitors each cell via the small white balance lead. NiMH batteries need a different algorithm entirely — gradual current ramp, peak detection at full charge, and no balance requirement. Use a NiMH charger on a LiPo and you risk overcharging individual cells to fire-risk voltages. Use a LiPo charger on NiMH and you'll undercharge and damage the pack.

Three charger families cover most needs. Smart multi-chemistry chargers (iMAX B6 and similar) are the gold standard — handle LiPo, NiMH, and Li-Ion, support balance leads, give you control over charge rate and cell count. The right pick if you own both battery types or expect to. Dedicated LiPo balance chargers are simpler — LiPo only, often with a fixed charge rate, cheaper, ideal if you've gone all-LiPo and don't need flexibility. Dedicated NiMH chargers are the cheapest option — slow-charge or trickle-charge units, ideal if you only run NiMH and want plug-and-forget simplicity.

What to also look for: a LiPo fire-safe bag for charging (small fabric pouch that contains a thermal event if a cell goes into thermal runaway during charge — buy one with the first LiPo, not the fifth), the right AC adapter if the charger doesn't include one (some units are DC-input only and need a separate PSU), and balance lead adapters if your batteries use a non-standard balance connector. Pair with the matching batteries — LiPo and NiMH live in separate sub-collections, browse the right one.
