Enhance battery life time

The problem: the battery of the detector's head needs to be exchanged every 2 or 3 years due to the lifetime of the LIPO battery.

Only the manufactor can exchange this battery, the detectors head must be send back to him...and during this time you cannot dectect...

So we have to take care of battery life time. There is a solution because battery life time depends mainly on the charging current:

- high charging current => reduced number of charging cycles

- low charging current => enhanced number of charging cycles.

For explanation of this, read carrefully this excellent article about lithium batteries : How to prolong lithium-based batteries

The solution: in order to reduce the charging current (default = about 400mA), simply put a 10 Ohm resistor in the charging circuit.

This will reduce the charging current to about 80mA and therefore maximise battery life time.

Of course the charging time will be several hours instead of only one or two, but this is not a problem, the dectector can be charged over night.
