I'm currently building a battery-charger based on **broken link removed** ciruit, but I can't seem to figure out how to reduce current flowing, without getting a massive voltage drop.
I tried with a resistor in serie, but the voltage dropped below the voltage of the battery to be charged, making the circuit useless. The reason for that I want to reduce the voltage is that the batteries are going to stand in trikle-charge-mode constanly. Being a part of a backup circui, in case of power failure.
The battery to be charged is a 180mAh 7.2V, I can't remeber if it was NiCad or NiHm. Supply voltage is +14.8VDC.
