Rick CTT and Kevin DGL brought up the fact that there are different types of “lithium” batteries.

This article explores the important differences between lithium-ion (Lion) and lithium iron phosphate (LiFePo) which I’ll summarize:

• Lion has a nominal voltage of 3.6V; LiFePo has a nominal voltage of 3.2V
• Lion and LiFePo have similar charge rates with LiFePo being somewhat faster
• LiFePo has a much greater discharge rate to power hungry applications
• Lion has an energy density of 150-200 watt-hour per kilogram; LiFePo is 90 - 120 Wh/kg
• Lion can last for 500 - 1000 cycles; LiFePo for 1000 - 10000
• Lion and LiFePo have similar shelf life with LiFePo being somewhat better
• Lion is more unstable and heats up faster, possibly leading to “thermal runaway” (i.e., fire and explosion)
• Lion contains toxic / hazardous materials; LiFePo is non-toxic
