I need an DC-UPS that can handle at least 300W, but I couldn`t find anything. So I come up with this:
InkedAnmerkung 2020-07-22 012832_LI.jpg
Battery: 4s2p Li-ion (3.7V)
PSU: 14.8V
P-Channel MosFET: IRF4905 (maybe? idk)
N-Channel MosFET: idk

Will it work? What should I change? Do you have any UPS suggestion?
Thanks!
