The chemistry of these cells is Lithium Iron Phosphate (LiFePO4) or LFP. The main advantage of LFP batteries is that they do not have the volatile thermal issues that Li-ion batteries have, making LFP batteries much safer than Li-ion. The other advantage is that they have very high cycle life of up to 2000 cycles, compared with Sealed Lead Acid (SLA) batteries that have a cycle life of about 400 cycles. This means that LFP cells can last 5 times longer than SLA batteries.
