GT Power C607D 1-6S 80W 7A LiPo Balance Charger (Mains/DC) (RB405448)

The GT Power C607D charger is a simple yet powerful dual power (mains 100-240V and DC 10-18V) multifunctional charger with built in LiPo balancing (JST-XH) for 2S to 6S Lithium batteries. It is packed with features that exceeds many higher cost units. Primarily designed for Lithium Polymer (LiPo) batteries, it can also charge Li-Ion, LiFe (A123M1), NiCd, NiMH, and Pb (lead acid) batteries.

It has a high performance circuit with maximum output power of 80W and a maximum current of 7A.

This charger has a number of innovative features including the ability to measure battery pack internal resistance and per-cell internal resistance - essential for monitoring the integrity of the pack.

For example:
1.  Packs that are as good as new  will provide a reading between 0 and 5 milliOhm/cell.
2.  Packs that have been used dozens of times, but still feeling fairly good will provide a reading between 5 and 10 milliOhm/cell.
3.  Packs that have been used even more, and start to feel weak will provide a reading between 10 and 20 milliOhm/cell.
4.  Packs that almost won't hold your plane or heli in the air anymore will provide a reading over 20-25 milliOhm/cell.

At long last, you can now check whether your battery packs are up to flying your model before take-off; perhaps saving a costly crash!

This charger features optimised operating software that sets the input current during charging and discharging. Especially for Lithium batteries, the software detects overcharging which may lead to critical damage to the pack due to incorrect input parameters. The circuit is disconnected automatically when a malfunction is detected and the alarm sounds. All the programs of this product are controlled through two-way linkage and communication, to achieve the maximum safety and minimise problems. All the settings are user configurable.

IMPORTANT notes on charger selection:
* Always select a charger that meets your actual needs.
* Always ensure that the maximum charge power in watts (W) will be sufficient for your needs.
* To determine the potential maximum charge rate for your battery pack, simply divide the maximum charge power of the charger by the full-charge voltage of your battery pack.
* A 50W charger with a 5A charge current theoretically, can only deliver 5A at 10V.
* An 80W charger with a 7A charge current theoretically, can only deliver 7A at 11.43V
* Efficiency losses (usually 20 percent) in the charger or the input voltage to the charger may reduce the charge current further.
* Setting the charge current too high and outside the capabilities of the charger is very likely to result in the charger overheating and potentially failing.
 
Theoretical examples using a charger with a maximum charge power of 80W
80W / 8.4V (2S LiPo) = 9.52A - making a 7A charge possible
80W / 12.6V (3S LiPo) = 6.35A (max charge current achievable)
80W / 16.8V (4S LiPo) = 4.76A (max charge current achievable)
80W / 21V (5S LiPo) = 3.8A (max charge current achievable)
80W / 25.2V (6S LiPo) = 3.17A (max charge current achievable)
