Hi All,
I am planning to build 3 (connected in series) AA battery charger which is MCU-controlled. I just want to know the basic. Each has 1600mAh capacity. Voltage is 1.2V nominal to between 1.4 to 1.6V after charge.
My questions are:
1. Can I use USB port for charging 3 AA battery NIMH? Will it charge up to 4.8V?
2. I am planning to read the temperature of the batteries with a thermistor. Do I need to place one thermistor for each battery? Or can I just place one and will already tell me the temperature of all.
3. What should i do to ensure have good thermal contact between thermistor and battery?
cheers,
