Hi anyone. I decided to replace my 4x 120ah gel battery's for 3x 280 lifepo4s.
Ive connected them and there up and running but they're performing far worse than my old batteries I should have a 12v 840ah battery bank but it's struggling to power a tv for a few hours and an air fryer for 20 minutes. I really don't know what I'm doing wrong. Any help would be really appreciated
thanks
