LITHIUM ION BATTERY FACTS. There are more than a few good reasons Lithium far exceeds performance of Lead Acid & AGM batteries. A lightweight option which offers charging efficiency and between 3000-5000 life cycles makes LiFePO4 the best choice for a better battery.
Lithium-Polymer Battery. Lithium-polymer batteries can be dated back to the 1970’s. Their first design included a dry solid polymer electrolyte that resembled a plastic film.
