Bad things happen


Now that i got my new battery(8.4v 1000mah, down below), my bluetooth receiver for my "controller" died. Now i have to get another one.


The battery has been fitted with a standard small plug. I have made a small charger for it. I have a power supply which can supply 5v, 6v, 9v, 12v, and 15v  dc, and 0,12 and 24 vac. To that i attached and lm317 which limits the current to 200ma. I feed it 9 volts and it takes about 5 hours to charge
