Lithium Polymer or Lithium Ion?

[kane]

Lithium Polymer (LiPo) and Lithium Iron Phosphate (LiFePO4) are the only types of Lithium Ion chemistries allowed for use (providing the design meets the build rules). It is important to note that different Lithium chemistries are not interchangeable.

There have not been tests conducted on other types of Lithium Ion batteries and it is not advisable you use other types unless you can prove they are safe for use in fighting robots.
