This is a heavy duty 2S hard case lithium polymer battery charge lead lead from ProTek R/C. This charge lead has 4mm banana plugs on both ends, as well as a 2mm banana plug on the battery end for balancing. This charge lead is specifically designed to connect a 2S lipo hard pack to ProTek R/C chargers, but will also work with any charger that uses 4mm bullet connectors for output, and an XH balance adapter port.

ProTek R/C is an AMain.com brand.

This product was added to our catalog on May 18, 2009.

PERFECT for charging 2S LiPo packs (Orion or Intellect that use 2mm bullet plug to balance) with my new Turnigy Accucel 6 charger. Thanks for supplying a hassle-free connection!

Perfect for Hyperion 0606i to Orion battery, cleaner setup since you don't have to have to use the balance board, just plug this into the port where the balance board wires normally go.

Works good, however the soldered fittings were so poorly soldered that they (I purchased 2) have all broke at the most inopportune time. I had to pay someone to re-solder the connections as I did not have my soldering iron with me at the time. Not that big of a deal, but... If I pay money for a product it should work!

Just what the charger ordered, well built and good materials through out. I only wish they offered different lengths.

I'm not sure if I just got a bad one, but I consistently get over voltage readings with this set. If I push down firmly and hold the balance lead I will get close readings between the two cells, otherwise I will see values jumping all over the place for cell #1 while cell #2 is accurately read.

This is the only way to go if you are running tubed batteries. This is so much easier than messing with plugs. Wish I had switched to tubed batteries a couple of years ago.

Love these charging leads! I've been using them for months with my inboard 2S LiPos. Now, I will say that I had the wire break on the little balancing wire bullet, but that was my fault for being too rough with it. I was able to re-solder it in minutes, and it works great again. You can't go wrong with ProTek products!

I'm FURIOUS that I didn't find these sooner!!! I've been complaining to my LHS that I don't know why in the world we are forced to use a Deans pigtail to connect to a balance lead that has a STUPID 4 inch long balance lead!!!! THEN, they said "just use this extension cord for your balance lead." ARGH!!! I KNEW that there HAD to be a complete cord without having to use a Deans plug...unfortunately, I bought and soldered up two sets YESTERDAY! Who cares, I'm still ordering this one...because it's the RIGHT STUFF!

Unfortunately when you buy LiPo batteries and a LiPo balance charger, that's not enough. You have to buy this little guy too just to use the balance options. It's a great wire set and gets the job done easily and hassle free. Bullets are banana plugs.
