The only battery giving me a problem is the lead acid Marine 'deep discharge'  battery used for field charging of the lipos. It has lost about 70% of it's capacity in seven months.

It provided six 12min flts when new and was purchased from Academy Surplus for $40. It has provided a total of maybe 80 flights ( 30 cycles ??? ). The problem is likely due to my maintenance ( lack thereof ). I left the battery in a partial discharge state sometmes for weeks. You can find maintenance needs on Google at agmbatteries, courtesy Earl Haury.

West Mountain sells a gell cell, 54#, 84ah, rated for 500 cycles @ 100% discharge ( 20hr discharge rate ), $149 del. I will see how it performs under our conditions.
