Does any one remember me? i need a cheep lipo set up

[Modding_out]

Whats up all you slightly homoerotic members I've been out of the game for a while now and quite simply I have no idea whats going on besides All of my stuff is out dated now, but ya know what i just don't care. But all my batteries are shot (yeh there still nimh) and that kinda puts a cramp on me having some dorky out dated rc time.

What i have: one 7xl emaxx with a MM, a rock rawler thingy, a stamped and a rustler. (last three are brushed)

So I'm thinking I need a cheap charger/balancer, 3 voltage cut offs and and 4 batteries, should I go i with a bunch of 2 cells or three cells?
