This is an custom-built order from one of my customer a few days back, his UMPC battery is unable to be charged by his notebook. After he have comfirmed that is the UMPC problem, not battery problem, he send it to me to make a custom charger for him. A picture is worth a thousand words.

Picture below: charging a 7.2V li-ion battery pack, the LED will go off when the battery is removed or the charging current is less than 70mA.


Technical Spec:
Type: Linear Series Regulation, Quick Charge Catagory
Maximum Charge Current: 1.1A(+/-5%)
Maximum Charge Voltage: 8.4V(+/-1%)
Input Voltage: 10V-12V
Input Current: 1A
Charging Speed: Reach 70% in 2 hours, 100% in 5 hours (for 2600mAH 7.2V pack)

*No trickle charge mode built in, no suitable for battery that have been drained down to 0%
*This is not a recomended way to charge your battery, although there are built in protection in the pack.
