Re: [Electric Boats] Do new batteries need to be broken in?

 

A Link 10 will do this as it knows the banks ah capacity and Peukert exponent. I think just counting ah would be good enough if you derated the bank to its 25 amp discharge time, which most mfrs publish.

How can you know when you are at 40%? Under load, the batteries are always lower than "resting state" voltage - which is what everyone says to measure - so how do we figure out what 40% is? Should we estimate from amp-hours and capacity?
