i have this li-po set up that i got with my ika zuchi.
i dont know what its volts or mah is but evike has this one listed as 11.1v 1500mah. so thats what i have if this is the same set up i got. i would imagine i could charge this li-po with its charger.
it costs a lot less than the nimh 9.6 and 8.4 batteries. i only wonder if it would wear out my krakens gearbox. i kinda think yea it would if it does what the li-po does with my ika zuchi
