Apologies if someone posted this already. Bought some Lithium Phosphate batteries and replaced my lead acid. MO magazine in Germany had a brief mention of these batteries--said they would work (can handle the heat unlike lithium polymer). Can't find the place I ordered them from right now, but they are 4 cells each and nominally 13.2V. Just one group of four cells has the same AH as the stock battery, but I figured I'd go for two since they are so small and light. the two together weighed 600 grams, compared to 4700 for the stock battery and box. Will let you know how it goes...
