lipo charger

[lemon191]

im looking at buying these:

http://www.component-shop.co.uk/html/ip2s20c1900.html

http://www.component-shop.co.uk/html/le-3.html

first are they suitable for each other ?

2 will that battery fit into a foregrip of a JG m733? ( i havent got a tape measure so dont know the diamentions but it would normaly fit a 8.4 mini)

3 will i need a extra connector to attach the mini tamiya on the battery to the charger?

cheers
