About this part

This is a ProTek R/C Balance Charge Lead with a 2S Balance Harness to 4mm Banana Plugs with 4S Balance Adapter. This incredibly handy charge lead was developed to provide users with the option of balance charging smaller 2S receiver batteries directly through the balance connector. This eliminates the need to remove the pack from your model, or charge through a switch!

Simply plug the banana plugs into your charger, plug the balance connector into a 4S balance socket, and plug the receiver pack into the female 2S XH plug, and you can charge your receiver packs in the field more conveniently that ever before! Simple, useful, and only from ProTek R/C.

NOTE: We do not recommend that you use this charge lead as the sole method of charging your receiver packs. This was developed as a way to simplify charging your batteries in the field. We recommend that you remove the battery from the model at the end of each day and inspect for damage.

Don't tell A MAIN, but I'd pay more for this little GEM! Works perfectly with my ProTek Prodigy 610 DUO through the 4S balance port adapter. I have a LIPO receiver battery in the front box of my JQ Yellow Edition Buggy and I no longer have to remove any thing to charge my battery(while balancing cells) Super Stoked!!!!!!
