MaxAmps Cylindrion Lithium Batteries
MaxAmps is going back to the future with our new Cylindrion line lithium batteries. These brand new batteries can be charged on a standard LiPo charger and provide the same voltage as LiPo batteries. However, they have higher energy density, double the cycle life, and are less prone to damage and safer than LiPo batteries since they are round, metal cased cells. Just like the NiMh batteries of the past, the round metal casing protects them from damage. 


      • 10000mAh capacity
      • 2S 7.4 volts
      • Same voltage range as LiPo batteries(4.2v per cell when fully charged)
      • Higher capacity(more run time)
      • Lighter weight(higher top speed)
      • Safer than LiPos(round metal cased cells)
      • Higher life cycles(double the life cycles of LiPo batteries)
      • Cylindric lithium cells
      • Lifetime warranty
      • Assembled in the USA
      • Choose any plug/connector
      • 150mm x 42mm x 21mm, 276g
