Great charging leads. had homemade ones before and these are much nicer and less money. unlike the another reviewer I have had no issues with resistance and I run an icharger aswell.

The white wire with the 2mm bullet could be longer. I ended up adding a 4 inch extension, so I could plug it into the battery less tension. Tension on the 2mm bullet wire will cause an early failure. Lastly, I use an icharger 406b with this charge lead. When charging the SAME battery with this lead, I am getting 3.4 mOhm per cell. With my home made lead, I am getting 1.8 mOhm per cell. Occasionally, cell 2 will drop to 1.0 mOhm per cell, with the protek lead. So, this leads me to believe there is probably a bad solder/bullet connection on one of the balance wires going to the +/-. For the price is is not terrible. It would have cost me more to buy all the stuff to make this one. I will probably end up redoing the solder joints, so see if I can fix the IR discrepancy with the protek lead.)

ProTek RC 2S High Current Charge/Balance Adapter (4mm to 5mm Solid Bullets)
Disappointed the Protek Prodigy 625 charger didn't come with some charge leads after spending $$$ on it. These charge leads are horrible. I thought at first sight that they looked like high quality leads, but after plugging them in one time I noticed they have a design flaw. The stretch wrap around these cable assemblies is bad for this purpose. This material is used to pull cabing. As you pull on the sheathing it stretches and tightens. May sound nice, but is doomed to fail on the smaller gage wiring (balance leads)using it with shrink tubing at the ends. Not what I'd expect after spending this much for leads.

If they don't offer a better option I will be returnign the leads, and charger.)
