promatchracing.com, currently i have 6 packs of promatch's ib cells (3 wcib4200s 1 shv ib4200, 2 ib3800s) i have only had 1 cell go bad the whole time i have had these batteries, and promatch being the great company they are, they sent a replacement cell that exactly matched what my needs where on the numbers (voltage, ir, runtime)

if planning on racing you can't go wrong with either promatch's EP or IB packs....but if your planning on "bashing" or periodically going to club races i would suggest getting the EPs as they don't take as much care as the IBs require....even though i would suggest still taking the same extreme care on any battery you get....

i currently use an lrp pulsar to charge all my batteries, and a novak smart tray to balance the cells out before a charge.

my process is much like that of many local racers. the night before a race day i get my packs out, and put alittle charge in them (180 seconds @ 6.0amps) and let them set on the smart tray till all the lights are out (.9v cutoff) then i put a decent charge into the packs (300 seconds @ 6.0amps) and put them back in my battery case. race day rolls around, and i take my pack out i need for racing or practice and i discharge the pack at 10amps with a 5.6v cutoff for the pack (yes i know .9v /cell is 5.4v) then the pack goes on the smart tray till the .9v cutoff is reached per cell. then i allow the pack to cool for 5-10 minutes (if the pack is warm to the touch), followed by charging the pack with a 6amp charge rate and 5mv delta peak. wait for the pack to peak then toss it in the car (trying to time so the pack peaks 2-3 minutes before my race) after the race i just toss my packs back in my case to wait for the night before a race again.

I don't drive for them. I just love these cells because all my other cells died after 6 mouths.

I love how everyone says the brand they recommend (usually the ones they bought) are THE BEST! Like no one else comes close.

Guess what, the cells all come from the same place guys! Sure there are differences in matching techniques, but so long as each matcher's technique remains consistent, then you should be able to get good packs from anyone.

Make sure you're comparing apples with apples when you look at the figures, but other than that why wouldn't you go with the cheapest option? Maybe don't go for an unknown, but as long as you've heard of them I'd go for price.

Works for me!

yes cells are cells, but the cheapest option isn't always best, i look at customer service for what i choose...which is why i run novak over lrp (notice a recent increase in the "lrp sucks" threads on these forums), customer service leads me to choose what i run, not if the price is $3 cheaper....
