I have an UPS with two 12v 7ah lead batteries. If I want to change the batteries I would typically go with lead batteries but here’s my question, can I use some portable mobile batteries to use it?
Because I have a 20000mah inui battery that is rated for 12v at 1.5A is this a good practice to buy several of these (since they are about 20 bucks) disassemble them and use them as ups batteries?
Yeah you need a UPS that’s OK with the BMS charge FETs opening when the battery is full.
When there is no trickle current the UPS will beep because it will detect battery removal.
Some are ok with it, on a thread I saw on reddit awhile ago about LiFePo4, people had reported a few models that worked fine with the upgrade.
