I have a 48 V pack of 2KS33P's and have installed many of their batts for my customers. You kind of need to qualify which series of batteries (4000, 4500,5000) of theirs you are asking about. If you're trying to do more than ~1000 ahrs and need to avoid more than 2 strings, you'll be looking at their 5000 series batteries. The 5000's have a better warranty, cost more. last longer, though they seem to drop in voltage, under load a bit more than say 3 strings of L-16s of the same capacity (comments welcome)...this can be an issue in some applications.
