Hi there,
I notice Mastervolt have a new range of Li Ion batteries, I know of a 3000Ah 24V bank going into a super yacht. Is this not a battery technology worthy of consideration as well? Each cell block has built in electronic regulation for individual cells. They boast of high efficiency, deep discharge, light weight and long life.

Again, I do not have the cycle chart handy, but hopefully James can post that.

My understanding is that lead cadmium are suited for standby operations such as telecomm back up. That means spending most of the time in float, with occasional short term high discharge rate with very high DOD available. How well do they cross over into a daily-cycle off-grid situation with moderate daily DOD?

It is why I never use em... never! If they are 5 years old, you are probably at the limit of their life. Replace em with flooded lead calciums and your customers (and you) will be happy for 20+ years. my .o2 Todd Sent from Finest Planet WebMail.
