I don't know how many of you have had this product on your radar, but they just released their 915 wh equivalent battery that will go with this motor setup. I have their current 320 wh battery with my current setup and it has lasted 6-7 hours without any issues. Now this new battery is 3X the size! That means full power all day on tournament day which is pretty exciting. The 320 wh battery is $599 and the 915 wh is $899. A little bit of sticker shock to be honest...but your paying for a whole lot more than just the lithium battery. Sealed battery case that floats...waterproof connections to the motor and controller...and GPS receiver that will track your entire path. I am pretty pumped to upgrade now!
