ISDT seems to be quickly becoming the Apple of Lipo battery chargers. The PC-4860 Safe Parallel Adapter is no exception. The 4860's case is machined from a solid billet of aluminium and provides excellent protection and heat dissipation for the internal circuit board.
The well designed balance port openings make it very difficult to accidentally plug in a balance lead backwards; should you manage to do so, the circuit board will protect itself, your batteries and your charger via 32, self-resetting fuses that not only protect the battery as a whole, but the individual cells as well.
You can connect the Parallel adapter to your charger using the included 19 cm, XT60 extension and the 15cm, 6s balance extension cables.
