WebOct 7, 2015 · I suggest to use 2x 14500 lithium ion cells in a 2xAA holder with a 9v-style snap. This gives 7.4 volts nominal. An added benefit is they are rechargeable and have much higher energy capacity. A low dropout switching regulator module can also be added for even better efficiency (you can get ones small enough to fit on top of the battery pack). WebSep 21, 2010 · NiMH Battery Charger Circuit Schematic. Around 2.6 volts drop develops across the LED which appears at the base of T1. Emitter – base junction of T1 drops around 1.2 volts. So 2.6 – 1.2 volts gives 1.40 volts. So the current passing through R1 will be 1.40 V / 10 = 0.14 Amps or 140 Milli Amps. The LED act as the charging status indicator.
