Are there ready-made 12 volt UPS with 18650?

Question

Computers

Good afternoon! I have a 12 volt motherboard. Are there ready-made UPS for such boards, with 18650 cells? So that when there is a power outage, there is no sudden shutdown of the board.
Thanks for the advice.

Answer 1

You can google "Uninterruptible Power Supply" - a typical use of ACS, SOT - power cameras, locks, controllers, etc. 2-3A typical for a penny ... though they are guided by acid batteries 12v7..9ah

Answer 2

You can take any battery pack with an initial voltage greater than 12 volts (4 or more) of the battery in series. Like these, you need to solder a BMS balancing module to them (carefully according to the diagram), add a power supply (you can use a pulsed 220> 24+ next power supply), add a step-down stepping inverter like that. In general, this is the topic of a normal such article. You can read more on alexgyver's blog
