Checkpoint Or Flightpower Saddle Battery
 

Just purchased a DEX410 buggy and need to order some saddle batteries. The store i normally deal with stock the Team Checkpoint and Flightpower Trakpower Dark.

Out of the options you have I would choose the Flightpower Dark series but I use these Intellect 5000mah from E-bay 23mm high so will fit original Durango and newer 2010 and 410R which accepts up to 25mm high.

The size of the Checkpoint is 69 x 46 x 23mm & The Flightpower is 69 x 45 x 23.5mm.
