Battery Question

[Re~Mix]

Okay well, sorry to take business away from you. But im thinking of trying to order all that I need from one place. All this distributor carries though is the smc 3600 matched stick pack, this should be very simular correct? As it has almost the exact same price. I also opted for thte 16x3 because I only run one battery at a time anyway, unless the 16x4 is truly worth the money. Im guessing I should charge these at 4-4.5 amps correct? And then discharge them after I run. Will this charger have an automatic cutoff for discharging and charging?

Also, I heard with NiMh batteries you can't run them all the way down. Say like until my truck literally stops? Thanks for all your help.
