Direct soldering should only be done if your concerned about the best possible voltage and IR from the packs. In testing a good connector will increase the IR by 1.5 milliohms and drop the voltage .04 at a 35 amp discharge. I personally think a connector is fine shouldn't make a big difference on the track but with our packs you have the option.

Originally the capacity was going to be 5200 but the pack would of been over 30mm in height so we decided to retool and make the pack not as tall so it fits under all the topdecks of the current offroad cars. So now the pack will be a 5000/28C.
What's the latest timing on these saddle packs?

There was a delay but it looks like we will get the sample pack next week. Once we approve it they will go into production which should take 1 month.

Simple question (I hope?)
What makes Li Po packs blow up and how do we avoid this? I talk to a lot of people who are keen to swap but they are worried about safety.
Thanks.

Someone asked on the last page how these packs are working in other forms of racing other than TC. Ran a 5000 pack last week in off-road in a buggy, tied to a Putnam 7.5 Brushless... Great rip, very consistent throughout the races (mains are 8 minutes. We weren't doing any heating (track was slick, figured we didn't need more rip!)

Well done, Danny... Wires out the top- even better!

They blow up if you overcharge them. The best way to avoid this is to follow the ROAR rules.


see http://www.roarracing.com/downloads/...ipo_Reader.pdf

and the rule book (starting on page 33)

follow the included instructions, use the proper charger set to the lipo function, never discharge them to far, and for soft side lipos, avoid damage. we have used lipos at our oval track in sedans, trucks, EDM, sprint, 1/18, and offroad truck for over a year with NO explosions or fires.

In the ROAR Li Po rules can someone explain the term "dual layer" safety feature.

i believe they are referring to either the "hard case" and the use of a "lipo sac" or the use of the "proper charger set correctly" and the use of a "lipo sac".

Question:
If you wanted to discharge a lipo 3600 or a 4800, using a pulsar 3 what you set the setting for?

Yes, you can discharge a Lipo. you need a discharger that can be set at a 3 volt cutoff per cell so for a 7.4v pack you stop discharging at 6 volts.
