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 power banks to use it?
Because I have a 20000mah “INUI” lithium power bank that is rated for 12v at 1.5A, is it a good practice to buy several of these (since they are about 20 bucks) disassemble them and use them as ups batteries?
EDIT : clarifications
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.
