Just curious if fast discharges can cause damage to flooded cell batteries?
I have a 5 x 140Ah house bank (700Ah). They are charged via wind
and 540w solar panels
I would like to use my inverter
sometimes to heat the Hot Water Service
Its a 1200w 220v element, and draws 130amps for about 30 minutes while it heats.
Im not concerned about losing the 75Ah from the bank as I will just run it when I have 90-100% charge state, but I was wondering if drawing high loads over that period of time will shorten my battery
life/damage my batteries? Effectively Im effectively draining 10% of the total charge (25% of usable charge) in 30 mins.
Thanks for ideas.
PS, my other option is to put a smaller wattage element or 12V in the HWS to slow the discharge rate if this is a healthier lifestyle for my batteries
