Hi all. Onr for our battery guru's here. I've been asked to work out a realistic life and battery type for a potential project. From the desired operating use, the cycle should be something like this:
Come off overnight charge, 33Amps discharge for 15 min 15 min rest (no charging available) 33Amps discharge for 15 min 10 to 15 min charging available, (Cycle then tepeats, 33Amps discharge for 15 min, etc..) Repeating 8 times during the day, with overnight equalising charge. If my sums are correct, we are pulling around 17Ah per discharge, if we recharge for 10 min at 100A we can put back 16Ah, but of course we cant get 100% full in this time. There is a Lifeline battery that I know of at 105Ah (20hr rate), AGM, that fits the desired weight specification for this project. With 8 cycles per day, of around 16%DoD per cycle, is it realistic to get 3000 cycles from these batteries?. If so they would last a year (375 days at 8 cycles per day). Various factors dictate AGM batteries (or other sealed type), no wet cells allowed. Is this a realistic life for this type of battery under these conditions? Thanks James Massey
