For a lot of Spark flyers, the Achilles heal is the battery, only lasting around 10/12 minutes from 1480 mah. The weight of this battery is 98 gms. There has been a few battery mods applied, that for a lot, does not give any real advantages due to weight increases. The 18500 li- ion battery is 2500 mah for a weight of 32 gms each! 96 grams for three, with the connector fitted, very little more! Has anyone tried using 18500 Li-ion batteries? If yes, what were the results?
