pilgrimvalley Posted February 24, 2021 Share Posted February 24, 2021 Sean, you said you were getting lithium titanate. they are very expensive, but are claimed to have a long life 50 years. the LiFePO4 batteries are relatively cheap if one does diy with a bms and have a 3000 to 5000 cycle lifespan an then will maybe have 80 percent capacity. 5000/365=13.69 years for LiFePO4 chemistry. in 13 years the battery storage chemistry may have an even better chemistry. i was hoping for the salt water battery that was once talked about. lead acid is old school --- lead weights for sure.
