I used DC-DC to get 3.3V supply from my battery with 3.6V capacity. I used large battery (connected number of cells in parallel) for long term operation of device (81Ah).
So my questions are:
-> I used 3.6V, 81Ah battery capacity (non-rechargeable)
Q.: My board required only 100mA to work so is it fine to use this battery?
(Meaning, does it draw large current and damage my board? Or what should I take care to control this current? Or does it taken care by my DC-DC or current drawn depending on my board's load requirement?)
Thanks in advance.
