|---|---|
| Cheap ($ 100/unit) | Costly |
| Less thermal run away | More thermal run away |
| Safe to charge 100% | Less safe for 100% charge |
Less energy density |
More energy density |
| Life is ~ 3000 cycles of charge | Life is ~ 1500 cycles of charge |
Sub-par range & charging in cold |
Temperature insensitive |
