Has anyone been running the new(?) Integy VESC Force SHV4300 6 cell pack?

I am charging with a Pulsar 2, discharging, throwing them on a smart tray, and I cannot get them to take or put out more than approx 3400 MaH.

I am at 6 amps, 30 delta peak, no trickle, discharge at both 30 and at 10 amps. I have run them through the Pulsar's matching function as well and no change in results.

All my other 6 cell packs are doing great (IB's). This is my only Force pack...

I have tried two different chargers: Pulsar 1 and Pulsar 2.

What am I missing fellas?

Thanks!

The Force cells work fine for me. I purchased them directly from Integy though. Make sure that each cell has a voltage. Some of mine were at 0V when received so I put 500mA into them, discharged to 5.4V at 20A then trayed them on the Integy 030 for 5 mins then recharged at 6A, 100mV delta peak and 115F temp.

I found these cells may trip your delta peak but the temp is only reaching 90-95F. Thats why I am at 100mV delta peak.

Also, after racing make sure that the cells have a voltage of greater than 1.25V on them when stored.

Which version of the Integy Force cells did you buy? Which p/n?

Thanks for the glimmer of hope I have the INT F43005S These What did you get?

If I understand, you had the pack of six barred together when you pumped 500 MaH into them and discharged to 5.4 (0.9 per cell). Correct?

I have charged and discharged and trayed to equalize thes multiple time now. Sounds likie I'll kick the delta Peak up. You are right - they don't get hot hot!

How many MaH are you able to get in and out of yours? Thanks!!!

I picked up the 43004's.

I have only run them once and they got 4000+ in and had various amts left at 20A to 5.4 discharge.

my buddy had the same problem you had with delta peak.

The key is to charge them fully, race them, then discharge at 20 or 30 amps to 5.4 V and let sit till next week. if you will store them, then recharge with 1000mA. You do need to monitor the cell voltage periodically. Mine were above 1.35V per cell until day 12 when I noticed one cell was at 1.27V. I recharged that cell with 300mA and should be good to go for next Sunday. I figure 1000mA gave me at least 2 weeks maybe 3 before I need to worry about these cells except the single cell.

If you run the next week, then all you need to do is take that discharged pack and put it on a tray for a 5-15 mins to equalize the energy in the cells. Then recharge as normal but use temp as a guide. Internally with an infrared gun should be fully charged at 135-140F or somewhere around 110-115F with an ICE external monitor.

Thanks RinkRat! I'll keep working with them.
