Went to Sabahoceanic and got 2x17670 but cannot find the charger for it. So went back home, dug out the old Nokia 3110 li-ion batt pack to get the protection circuit. Got a cheap dual desktop charger for the same fone. Dismanteled the desktop charger and soldered the 3 wired contact to the protection circuit. Got a piece of 2x4 wood and used a nail as the +ve and a battery serial connector plate from a cheap rc car, bent the plate and anchored the +ve with 2 small screws and used the spring as +ve. solder 2 wire to protection circuit batt tabs ( the tabs are soldered to circuit and welded to batt) connec the wires from the circuit to contacts, plug in supply and success!!!
It took 6.5hrs to charge a piece of 17670 to 4.25V at which point the desktop charger indicator changed gradually from red to green. My supply is rates as 4.5V 300ma.
