Recent trends in batteries and cost reduction of them have really changed the norm in robots. Over the past few years the cost of lithium batteries have decreased significantly. This has led to most competitive robots being run on lithium polymer (Lipo) or lithium iron phosphate (LiFePO4 or just LiFe) often referred to as A123s as the leading battery manufacturer.

Additions:
- Lithium Ion Polymer (LiPo) The all new top of the line Cell, Extreme capacity, Extreme lightness, Extreme cost, these cells are however limited in the current you can draw from them before they burst into flames, While it may look cool fire is generally not regarded as a good property for your very expensive batteries to have. Derating is unkown at this stage but will likley be in the 20% region as you simply cant pull too much current from them. see LithiumIonPolymer

Additions:
- Lead Acid / Sealed Lead Acid (SLA)which are the cheapest type of rechargablle cell but (especially in lighter bots) they loose capacaty when high currents are drawn. Derate quoted capacity by about 60-70% see LeadAcid
