Re: Wiring In Series (pro vs con)

A note about series vs. parallel...


Batteries from the same mfg, same rating, etc. are rarely actually exactly the same capacity. Of course the consistency varies from brand to brand. For...

Re: Wiring In Series (pro vs con)

FWIW, the original inventor (Kurtis Kelley) has told us about tests they did where they discharged the batts to 0V, and let them sit for a month with a resister across the terminals. This would be...

Re: Wiring In Series (pro vs con)

yes, 10.5v is considered 0% SOC. I can't speak to "all lead batts", as every type/brand may have different characteristics. However, I agree with Maine Sail (as I always do) that all Pb batts need...

Re: Wiring In Series (pro vs con)
