LiFeYPO4 Batteries
Lithium-ion
Lithium-ion is a far more efficient battery and the Lithium-ion technology is cleaner, lasts longer and wastes less compared to the Lead-Acid Batteries.
Lithium-ion is completely maintenance free and with a greater DOD (Depth Of Discharge) you will get up to 80% compared to Lead-Acid which is 50%.
Their lifespan is 10 years plus with around 6000 cycles , this makes Lithium-ion a better investment long term.
