Certainly there are pros and cons. Here a list of some of them. Everybody
will weight these differently in deciding what to use.
- Highest energy density: lithium-ion
- Good energy density and lifecycle: lithium iron phosphate
- Stable chemical and thermal chemistry: lithium iron phosphate
- No thermal runaway and safe when fully charged: lithium iron phosphate
- Portability and lightweight characteristics: lithium-ion
- Long life: lithium iron phosphate and lithium-ion
- Low costs: lithium iron phosphate
