Lithium-ion battery

Lithium-ion batteries of the LiFePO4 type are extremely durable and can store five times more energy over their lifetime (4000 cycles, 100% D.O.D.) than premium lead-acid batteries of the GEL type (1500 cycles, 50% D.O.D.). Because of the deeper discharge 100Ah of LiFePO4 is comparable to 200 Ah of GEL. Furthermore, in comparison with GEL the LiFePO4 type weighs 60% less per kWh, has 50% less volume, higher working efficiency (96-99% vs 80-90%), lower self-discharge rate (2%/month @25 °C), and allows use of the full battery capacity without damaging the battery.
