I have more than 100 12V@7Ah Sealed Lead Acid batteries that I will like to use to build a small solar system to use it as a backup when power is lost for critical loads such as refrigerator and illumination.
Since I got those batteries for pennies, i would like to configure them so when they go bad I just replace them with a bigger battery that has the same capacity.
Just as an example:
Configured at 24V (2 in series 14 in parallel) in theory i will have a battery of (12Vx2)@(7AhX14) 24V@98Ah
Then if i do that 4 times my system will have a total of 24V@392Ah
that can be replaced with eight 12V batteries that have the same 98Ah
Has anyone done something similar?
The thing is that I have the batteries sitting there and i want to do something with them.
