The XT60 XT30 2-in-1 parallel charging board supports up to four 2-8S battery packs of the same type and cell count, allowing parallel charging from a single session. Gold-plated connectors and a durable design provide efficient charging and long-term reliability. 18 AWG silicone wire and connector deliver a secure, low-resistance connection. 40A fuses between any two battery groups protect the circuit from overload. For drone enthusiasts, model crafters and professional players, this parallel charging board simplifies battery management by enabling multiple batteries to be charged simultaneously. Use scenarios: - FPV drone race prep: charge four identical packs at once to shorten setup time. - Workshop / model building: keep several spare batteries ready for ongoing projects. - Field events or teams: refresh multiple packs to minimize downtime between flights.
