Hi-Energy 3S 4000mAh 40C Car Li-Po Hi-Energy O-HE3S1P400040C battery packs are designed to offer great value for money yet still deliver great performance for most sports applications.
All the cells in a pack are carefully chosen to match the impedance and therefore discharge evenly. This ensures that the pack stays in reasonable balance during discharge. If the cells are at the same voltage after discharge it then makes the re-charge faster and extends pack life. Cell connection is by ultrasonic welding with lead-free soldered power cables.
The main power leads fitted to each pack are suited to the maximum discharge current that the pack is capable of and are conveniently pre-fitted with a T type connector. This style of connector is used by many aircraft, helicopter car and boat manufacturers as standard these days such as ST Model, DHK etc.
The balance lead is the XH type, which is matched to all the Ripmax chargers and many others.
