Typically you don't want your packs to be much higher than 140 degrees Fahrenheit. If your using them in normal applications they should never reach this temp.

Not sure I understand what you want to know. What do you mean by expecting to see a higher number ?

If you run frequently you can leave your packs stored between 3.6v to 3.85v per cell. This is the voltage the cells should have when resting off the charger. Just store them in a cool dry place. For long term storage it's best to be around 3.85v per cell.

Danny,

Whats the world on these 1/10 motors??

RC Pro North Div Round 3
 

We ventured to a relatively local track for the 3rd and final round of the RC Pro Series North Division. Fort Dodge, IA is about an hour and 45 mins from us. Turned out to be a bit of a light turnout and was shortened to a 1 day event. The track is a unique surface that is somewhat intentionally intended to blowout pretty severely. Lap times rise dramatically as the surface deteriorates and you are constantly trying to chase the "smoothish" line.

I was able to TQ Pro Electric Buggy. My new XB9 '13 E Conversion felt good all weekend, including turning the fastest 1/8 buggy lap of the weekend in round 2 of qualifying. Because of the abbreviated format Electric classes were cut to double A-mains with both scores counting. A1 went well after a bit of a rough start I was able to regain the lead and cruise home for the win. A2 came after all the longer Nitro mains were run and the track was really beat by then! Got a better start this time and had built up a sizable lead, late in the races things fell apart a little and a fierce battle over the last couple laps ensued with John Taylor but I was able to eek out the win on the last lap to take the overall. Found out later we had a screw backing out of the LF castor block which was limiting my ability to run Right. SMC batteries were great and my Novak Activ8 with 1950KV Ballistic8 was flawless as always.

Overall a great finish to the North Division. Taking the North Division Championship in Pro Electric Buggy for the 2nd year in a row! We are extremely happy with our current equipment. A big thanks to my sponsors: RC America, Xray USA, O'Donnell Fuel, Pro-Line Tires, Novak, Picco Engines, Triton RC, Futaba, SMC and UpGrade RC

Next big race up for us will be the Futaba/OS Nitro Challenge in St. Louis, July 19-21

Ok let me try to explain it better. If I run a pack on Saturday and charge it on let's say Tuesday will it show a different mah then if I charge the pack right after running it on Saturday? Hope this explains it better. I guess I was expecting to see a lot more mah out of the pack after 8 minutes.

Let me try and clarify how I read it. You pulled the battery pack out of the SCT after an 8 minute main on Saturday. When you went to charge it on Tuesday, there was still 3800MAH left in the battery.

You are wondering if you would have pulled it and charged it immediately on Saturday, if it would have shown a different MAH?

Am I correct in how I worded it?

Nah, His saying that he put 3800mah back into the pack. His just wondering if that number would change if you charge right after or wait a couple of days.

You can check the motor thread and see pics on our Facebook page.

Hope to have these soon but the factory making these seems very busy so I'm not sure when they will be in stock.

Correct. I was told here on the forums that if you let a battery sit the voltage will come up and if you charge packs after they sit you can't get an accurate number of mah you're putting back into the battery. This sounded a little fishy to me but I figured I'd ask.

Not really the mAh that got removed from the pack is the same on Saturday as Tuesday. There might be a bit of self discharge but not much.

If I understand you correctly you we're expecting to see the voltage of the pack lower after a run or having pulled more mAh from it.

The voltage does rise a bit once you remove the load this is normal but it doesn't take long for it to get back to where it should be. Actually if you lit it sit for a long period of time it will nee a bit more mAh as it will have self discharged some.

I think it surprised him that it didn't take out more mah. That's what you call good packs!:D

Thanks. That's what I thought. I was expecting to see a lot more mah used. Tekno SCT410 with a Tekin Pro4HD on a relatively loose outdoor track. First time out running this motor and an 8 minute main with these batteries. No fade near the end of the main where my Nanotechs would start to fade on my lighter SCTE around the 6 1/2 minute mark. Also got to use my 4600 shorty packs in my 17.5 SCT. No problem making an 8 minute main with consistent power all the way through. Thanks SMC!!

Packs with good mAh and low IR means they will run strong and consistently throughout the discharge curve. Glad you enjoy your new packs.

I am running a Team Durango DEX408 1/8 E-buggy with a Trinity D8 1950kv motor. This car takes two 2S Stick packs. What batteries do you recommend? They will have to make at least 10 Minute mains on a track that is 200x125 with a 200ft straight. I would like to maintain as much punch as possible, but keep the weight down as much as possible. I used my dad's SMC 7200mah, but they are a little heavy. I currently have the factory spec 5000mah packs, but think i would benefit from a higher discharge rate. I was looking at the 4600mah shorties, just wasn't sure if they would make the 10 minute main.
