Got my 4s packs and all cells were within .01 of each other , pack construction looks to be top notch ! Thanks Danny/SMC for the fast service

The out of spec 7200s are coming in today and are now listed on our site.

These packs have 200-300 less mAh than the regular 7200s. The IR is every bit as good so you can expect the same power from these packs.

I just ordered two of them.
Race Formula 7.4V 7200mAh 70C Deans Lower mAh
Item #: 7270-2S2PDLR
Danny, are the Deans connectors a issue still?

Danny/SMC 06-14-2013 06:31 PM

Never been an issue with connectors with this supplier and as previously noted we're not buying from the other supplier anymore.

hey I need to switch my dry cell in my starter box. so this is what im thinking the biggest 4s battery and the biggest 3s battery for my comp heater does the c rate affect these item at all what would you use for all day use for both I do feel safer with over kill so my boxes don't die and the comp heater will be running a lot. thanks rob.

Some testing with SMC 7200, Turnigy Nanotech 6600x2 and Turnigy Nanotech A-Spec 6200.
SMC is allmost brand new. Nanotehcs are 6 to 12months old and they are charged up to 30Amps current.

Test was done by stress batteries by constant 55 Amps until cell voltage 3.0V. X axel is not mah its more like how many readings software get while testing batteries.

The C rate or IR should give you more power for your starter box. Not sure what a comp heater is ?

When I tried to sell packs with true C rate specs using my own C rate testing method I tested various 6500 to 6800 packs. All packs were new. The 6600-65C is a Hobby King Nanotech.

You can also check other data on these packs such a cycle life testing and IR testing on this thread I did on Hobbytalk.

I've never been one to hype up the packs I sell with special names and claims but one thing I'm proud of is that I have always sold packs that I believe to be as good if not better than what others offer. This is why I did the test on Hobby Talk in August of 2012.

Still not familiar with this. lol

Do you know how much amps it uses ?

Canadianrage 06-15-2013 08:31 AM

Any guess as to how long the 7200's are out of stock for?

The inboard 7200s are in stock and we have a great deal on 7200s with 200-300mAh lower. You can see these in the out of spec section. The IR is just as low if not lower than the regular 7200s so these out of spec packs will have very good power.

I would think for this the C rate has no impact. Just need to figure out if you can do a race day on a 5100-3S or 6500-3S.

yes I think im still going to go with the 6500 and high c rate to be safe. A lot of the tracks are supplying power now. so who knows maybe I sell this and get the ac version. I did get a chance to run that 6500 pack again all day in the
4x4 sct it came off at 3.91 and 3.90 and that after 10 minutes.it keeps it punch though the hole race. So im going to be placing another order soon. going to try out those saddle packs for sure.
