Ian, if you're seeing discrepancies between cells then an EQ charge is the only real solution. If an "EQ"charge hasn't resolved the imbalances, you probably haven't achieved it. One common mistake I saw among my neighbors was confusing unregulated charging with equalizing. Surrette has published so

[RE-wrenches] Battery voltage set points and specific gravity

2011-09-19 Thread Ian Eastman
Hi. I was hoping that someone could simply answer a couple questions on battery voltage set points and specific gravity of cells. I'm a bastard son of generation "grid tied", and in the last couple years and a job change have just begun building and servicing battery systems. First off. I was readi

Hi Ron, The recommended maximum number of strings in parallel in a lead acid battery bank is 4. Each string consist of the number of units required to meet the battery bank voltage (12V, 24V or 48V). Higher than 4 strings in parallel is not recommended as the risk of unbalanced charge between
