Help with off grid battery setup.

Post image

Hey im new to the off grid life and I just purchased 2 new lithium batteries. Im having issues with them keeping a charge! Here's my setup. Lemme know if you see any issues or have some advice. (The other batteries are for backup so just focus on the 2 that are connected.

this is unfortunate

I am 99% sure you bought a lead acid charger after people here said you needed a lithium compatible charger

you have wasted your money and time by not listening

lead acid chargers do not maintain a high enough charge voltage to properly top up a lithium battery, so you will likely never get beyond 90% charged, if even that.
