Hi,
I have a camera that runs on 7.2V battery. I'd like to use an external battery to run it.
I have two options here and since I have no knowledge in electronics would need your assistance.
1st option: 14.4V 95Wh battery
2nd option: 7.2V 7800mAh battery.
If I choose the first option I would need a regulator (not sure about the terminology here) to down-convert from 14.V to 7.2V. If I choose the second option I can connect it directly.
Afaik the running time of a battery depends on the capacity, measured in mAh. i found out how to convert Wh to mAh:
(mAh) = (Wh)*1000/(V)
This means that the 14.4V 95Wh battery would give 6600 mAh. This is less than the 7.2V battery. So in this case, would it be better to use the 7.2V?
(2) Some of the regulators convert the voltage to 8.4. Is it a bit higher because of loosing energy on the conversion (but actually you get 7.2V)? Would it still be safe?
Would appreciate your advice here.
