ansmann charger good enough for lipo

[B4 Sloth]

Having got my brushless set up I am now leaning towards lipos. I have the deluxe base charger which is capable of charging lipos, however is it good enough as it is or do i NEED other bits and bobs to make it work properly..ie balancer. I assume that when the charger is in lipo mode it detects the 'fullness' of the battery and charges accordingly. How else would it work if the lipos dont need discharging..or am i missing a trick?

Next question.best below £50 lipo stick for my B4 is?
