Just bought one of these for ease of starting engines avoiding dragging a lead acid around with my Hangar 9 starter.
My issue now is what 3 cell Lipo "actually" fits. Align recommend 1800 -2300 maH. But surfing HKing there is nothing that will fit unless you drop down to 1500 maH. Max size in mm for Lipo to fit in body is approx 105 L, 34 w, 25 H.
