Reply to comment by MadLintElf in Fires from exploding e-bike batteries multiply in NYC — sometimes fatally by zsreport

Are they Lithium Polymer, or Lithium Iron Phosphate?

The latter have slightly less capacity, but are considerably less spicy and can handle thousands of charge cycles so tend to be used more in situations like this.

The one's at work are Lithium Polymer, we need the energy density for the devices. That being said I'm glad we went with them based on the track record.

We did have an option for cheaper batteries, but the company wouldn't provide a warranty since we would be buying from another manufacturer that only covered replacements. They specifically had in the documentation that they were not responsible for overcharging the batteries or battery failure damages.
