i just use the voltage values like 0.07v instead of the mv stuff it confuses things. T35s use voltage values with decimal points. its the pitbull and millenium using the mv values that are confusing some i think

OK to clear things up I am using a Millenium to charge the packs, with the Voltage Threshhold set at 4mv per cell, 24mv per pack.
They still come off the charger too hot to hold in my hand for more than a second.

Hi Guys,
Is it any way that I can stop my Novak Millenium charger from having false charge on my HV battery?

The Pitbull also uses a decimal value, just like the T-35, but it shows it to 3 decimal points, where as the T-35 only shows it to two decimal points.

Do you guys use a tray to discharge the HV's? If so do you use it before a charge or when?

I used a friends brand new pack of fantom HV's and my t35 to charge them at a club meet last weekend. I charged them at 10 amps .09 peak detect and they were simply unbelievable. We also had two new packs of UMH but in my opinion the HV's were far superior. I'm now sure I will be getting the HV's after comparing them against the UMH on the track. However I did find one thing rather surprising, at the end of the charging the HV's they only seemed to be mildly warm to touch, nowhere near as warm as I would have thought. Should the pack be hot to hold in your hand after charging at those sort of numbers.

Assuming the cells are cool before you put them on charge, sounds like something is wrong somehwere along the line for that to happen, although I couldn't put my finger on what.

Grizzbob: UMH act just like SMH's in fact I think they are the same cell with new shrink.

Rowdy: I would go with the new GP3300 it will run as good as an HV but has more capacity and it's cheaper.

To All: On a 6 cell pack I reccomend 70 to 90 mv or .07 to .09 volts. The pack will peak in the 140-150 farenheit range.

F&K: Use a 70 to 90 mv peak detect for the entire pack. You can also charge the pack for 200 seconds or so and then discharge it and then start the charge. This should fix the false peaking.

Erik R.: If you usa tary afte the cell has been discharged and it's still hot this will keep the voltage up but will drop the runtime. If you use a tray when the pack is cool and then start charging it right after it was on the tray this will be better for the runtime. If you use no tray this will keep max runtime but it

Danny is there a formula or a "rule of thumb" to use when increasing the charge amperage on the HV cell. Example being if a person wanted to test the affects of using different charge rates, then how would he/she know what delta peak setting to use. Thanks...

Danny - how long until you get in the new GP3300 cells. Do you have any cell numbers for them you could post ie runtime, voltage, IR's.

fhubbard: When using 10 amps or more I would use .07 or 70 mv. For 8 or 9 amps .09 or 90 mv will work fine.

Rowdy: We already did a small batch of GP3300 and were waiting on a new batch. Out of the first batch runtime was 400 - 430 with 1.13 - 1.15 voltage @ 30 amps. Actual IR of 2.8 - 3.3


I heard that NORRCA will approve them on 1st of Sept. Not sure about ROAR.

Anyone know the formula for working out the mA HR of a pack at the end of a charge on the t35?
