Apex RC Products JST-XH 4S 6" / 150mm Balance Plug Extension Lead - 5 Pack #1092

I have an item called a Bat Safe... It's a specially insulated and ventilated box, designed to protect you from flames if your LiPo battery should catch fire.The battery goes in the box... the charger goes outside the box... and there isn't enough wire to get the one to connect to the other. But 2 of these extension leads will do the job.They aren't any more substantial than the wires on the battery itself, but they're equally strong. The connectors fit tightly.For this purpose, I recommend the purchase of a set of these jumpers.

Ordered these to go with the new parallel charging board from Josh Bardwell. Most of my 4s packs have short balance leads and trying to get 6+ packs going at the same time with short leads is a pain. these make it super easy to get all of them on the board and inside my charging box.

Pretty good for charging lipos with short balance leads on a balance board where it’s hard to get the connectors in.Would be 5 star, but one of the 10 I ordered was wired backwards. Luckily I didn’t hurt my battery with the arcing of the shorted balance wires!

yes

These work great. Just as advertised. The quality appears to be very good.

Works well
