Supply voltage, 14.8V or 11,1V

[baluba]

Hi, i have 4 Li-Po cells, 2200mA. Should i use 3 cells 11.1V or 4 cells 14.8V to power my MPP? i have read on the forum that the bottom voltage is 8.4 what about the upper limit ?

The operating range for the LT1054 voltage converter is 3.5V to 15V, but its absolute maximum voltage is 16V. In that case, a 14.8V power pack should be ok.

Thank you for the advice.
