Works great, good value, but be carefull not to reverse power the unit (having the power supply plugged on the module and the battery at the other end, and unplugged the charger). The current flowing from the battery back to the charger ruined the IC on one of my modules... I bough replacement ICs (cheaper than the complete module). I added a N Mosfet on the output +, the gate being connected to the input +. The it is blocked when input voltage is less than V_battery+Vth and avoid reverse current damages.

An excellent product, small in size and powerful enough. One goes to charge the battery and the other to power the LED module. Recommend.
