I just saw you pricing for the 3800 and WOW, I just wish Scotty would allow them at the Vegas race.

How do they compare to the GP3700? Scotty is going to allow those.

I mainly run stock but will run 19T at vegas. How would a 3300 compare to a 3700 to a 3800.

Looking to try and determine do I need to go to a 3700. Will the 3300 be going by the wayside soon?

I am in the market for some new packs soon. 3-4 packs.

Thanks...

Hi all,

I have a question regarding my four PMR GP3300 packs...lately, they've been steadily loosing capacity when charging...when I first got the packs, they'd take around 3200-3400 mah when charging at 5.5 amps with a 4mv/cell cutoff.

I've had the packs for probably about 10 months now, and lately I can only get them to take about 2600-2700 on the initial charge at the same settings. I always tray them on a Novak Smart Tray at the .9V cutoff before charging, and they're used about 3 times per week. If I remember correctly, the numbers on the packs average around 420 secs/1.165V.

Just wondering what I can do to get the capacity back up. My local track has been running 6 minute heats with an occasional 8 minute main, but I have a hard enough time making 6 minutes with my 12x2 Orion powered B4 when I'm deep into the trigger, and if I REALLY finesse the car around the track I can just barely make 8 minutes (while other racers can run for several minutes after I've gone dead).

Any suggestions/comments on how to "revive" them would be appreciated. They run VERY strong for just average voltage packs, so I can't complain about their strength.

Thanks in advance.

bigdog... i recently picked up some PMR 3300s..and 3700s. the 3700s perform JUST as good as the 3300s but it has more run time. in stock.. i am able to run 6-6:30 of punched racing in stock. i ran the 3700s and i was able to do about 7:30-8mins before i felt a fade one thing though... 3700s are 10 grams heavier. and the IB3800s are 15 grams heavier when compared to the GP3300s.

i can get a good 6 mins of runtime in 19T with my 3300s also. its really up to the place where you race if they'll allow 3700s. either way.. you cant go wrong when you invest in some new promatch packs

Johnnyshore: 1st off, change the voltage cut off on the Novak to .1 or .2. Then get one of the "old" Promatch trays. Leave the pack in the tray for 24 hours. Use this method everytime, new packs or old packs. It will help your old packs a great deal but it will not make them like new.

I have tried using .2V cutoff on the smart tray, and it ups the initial charge to about 2800mah. I know the newer 3300's aren't as durable and lasting as some of the packs from back in the day, but I wasn't expecting to lose 500-600 mah over a 10 month period.

Like I said, the packs are still very strong so there's no complaints in that category.

Thanks.

I've had the same exact experience with GP3300's. I had a bunch of 6 cell packs for about 8 months and the most MAH that would go into the cell was around 2800 as well. I tried zeroing the cells on my Integy Tray but it only boosted the mah about 200. The packs still ran strong just like you said but after time, I guess these cells loose some capacity.

I've been running Promatch Batteries for around 2 years now, and I really love them; excellent packs.

Just a quick question, when discharging my PM GP3300's with a 20 amp bulb discharger, with a 5.4v cut off switch, I have had two cells vent on two different packs. When I discharge on my Turbo 35 GFX at 20 amps I don't have any problem. Needless to say I'm not using the Bulbs anymore, just wondering why? Thank you in advance.

Using the "old" Promatch tray for 24 hours may get you another 200 mah or more. NEVER store your batteries with any charge in them! REPEAT, Never store your batteries with any charge in them. If you have the money to buy enough trays, store your batteries in the Promatch trays for days or weeks or months. Remove them an hour before charging. You will be impressed with the performance.

Polesitter: I have seen cutoffs that go well below 5.40 volts. As soon as a cell goes into cell reversal, it will vent. Cell reversal cause a major loss in performance. So your vented packs are now junk for serious racing. When dumping packs, use a higher cut off, then tray the remainder.
