ProTek RC 2S High Current Charge/Balance Adapter (4mm to 5mm Solid Bullets)
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.)
