SMC 4000/25C/3.7V single cell Hardcase pack.

I just read back 2 pages and must be missing something, clue me in here. Why are some of you turning the ESC switch on with the newer BL ESCs? As far as I've learned, the ESC switch should NOT be turned on when using a Rx pack. I've used Rx packs as far back as the 80's with brushed ESCs and never once had the ESC switch on. Also didn't get any wierd issues either.
If I remember correctly, don't the oval pan car guys run RX packs in certain applications? My Maveric car has miniature cell slots for the old school Sanyo Rx pack.

When will these cell be available in the UK. So far, I haven't come across any shop advertising them for sale.

Has anyone gotten this lipo with Tekin RS? I've read that taking the red lead out and turning both switches on will eliminate dumping feeling. Can someone confirm?
Thanks.
Thanks.

The RS seems to have some issues on the low voltage. I plan to try mine this Friday. I picked up a killer deal on a Sphere for backup, so far it seems to do OK. I only think the RS' advantages are the ease of programming and footprint. If I have to use a Sphere, I think I'll be just as good off.

I run a Tekin RS in my 1/12 scale. Although I run 4 cell, I have run an RX pack in my car to get maximum voltage to my servo, receiver, and transponder. I had to remove the red wire from the servo connector to prevent the ESC from using the RX pack to power the motor. I noticed a problem with power issues when I first ran the Tekin RS with the RX pack. I spoke to Tekin about it, they told me to remove the red wire from the connector to solve this problem. Once I made this change, the power issue went away. Both switches do need to be turned on to make everything work. I'm thinking about getting this new SMC 3.7 LiPo and trying it out.

You will not be able to match the speeds of 4 cell pack if you plan on using a 5.5 motor. I think you would need to use a 3.5. That being said our one cell Lipo has roughly 425 seconds of runtime at 35 amp discharge. A good pack of 4600s will cycle out around 465-470 but Lipos seem to run more effeciently than NiMh cells so runtime should be similar.
I think it needs to be tested as the dumpy feeling may be much more apparent due to extra voltage drop created by the lower turn motors.
Our goal to go with a 4000mAh pack is to try and slowdown the mod class. So if you can't make time with a 3.5 and have to use a 5.5 then it will drop the speeds.

As soon as I get my grubby little paws on one of these packs, I'll keep you posted.

Thats all well and good once single cell becomes standard but out here there is no push to slow 12th down so I can't see people switching from nimh until there is an alternative for 4 cell thats competetive with people still running numh. I've gone lipo for my TC (SMC's naturally ) so want to switch for 12th but at the moment it doesn't look like there are many options. I have a 3.5 from 5 cell mod that I no longer use so I might pick up one of the packs and do some testing

I understand we can't have the perfect solution for every track. I was asked to put less capacity in this pack by Josh Cyrul as he told me the speeds now are way to fast. If you the racers like going this fast then 4 cells are the way to go. The problem is that it will be getting harder to find fresh suc-c race cells as Lipos keep taking over.

Are you folks using voltage regulators with receiver packs? If not why?
