Maxxamps batts

[GorillaMaxx360]

I got a couple of questions for you guys.

1.) what kind of runtime would i be expecting to get on 2 5000mah maxamps batteries with my setup (very rough estimate) i was thinking about 20-25min.]
2.) can the ice charger charge these batts.
3.)aprox. how long does it take too charge one of these packs safely like at 5 amps.
4) what else do i need to have in order for charging to work, for example a balancer of some sort or some battery accesories.
5.) is there anything else i should know about these batteries

(my setup will be sometype of neu motor and this car(look on last page for newer pics) thanks guys
