The two most prevalent types of battery chemistry are the Lithium Nickel Manganese Cobalt Oxide (NMC) and Lithium Iron Phosphate (LFP). Both have their pros and cons. NMC is a more advanced chemistry capable of delivering higher currents with higher energy density. But it is also more sensitive to temperature. With no cobalt, LFP has low toxicity, offers a longer life cycle and is more stable but low on energy density.
