LiPo heat dissipation

[SniperGaulois]

How many Watts of heat are dissipated from a LiPo pack for every 100W that goes into movement? it's a kind of exothermic reaction? presumably it's a lot less than old-fashioned lithium...

im not positive but i don't think any heat actually comes from chemical reaction but from the internal resistance of the battery. in that case it would just be the current squared multiplied by the resistance.
