The CRC Rocket Fuel is supposed to be the lowest IR out there. I have seen around 1 mOhm with it. https://teamcrc.com/product/37151-1s...k-3-7v-low-ir/

Just cycled my CRC batteries. Ones [email protected] and other @ 1.2. These are last years batteries. Charged at 15 amps and discharged at 20 amps.

Wow those are some pretty amazing numbers. Much better than my two worn out packs at 19 and 24 milliOhms. Always charged at 1C (8 amps) and discharged at whatever a 17.5T pulls for 8 minutes, then storage charged at the end of the night.

SMC - lowest numbers on all the packs I have tested and best price too.

They were the first company I looked up. No 1s packs in stock.

I emailed him and he is working on a new 1S pack. Should be back in stock soon.

Might try Factory Xtreme. They have 1s packs in stock. Not sure of IR numbers though.

Ive seen .8 IR out of some of my 8200 rocket fuel packs when cycled at 40 amps

I've got a new Rocket Fuel 7,500 that I've seen down to 1.2 so far. My old SMC 8,300 did as low as .7 last year when new, but this year can only muster 1.4. I would have purchased another SMC if Danny had them in stock.

I also almost exclusively used Danny/Smc going back to nimh cells.

In all the years of lipo purchases I have only gotten one pack that was mediocre. It was a discount/sale pack and even then was still better than most other brands off the shelf producct

Most of his packs are 1.0 ir or less. when new. Really quality performance packs.

Hopefully he will have packs available again but I imagine the days of quality batteries and good value are long gone. Like everything probably going to be big jump in $$$.

I'm running 17.5 1 cell, typical stock class on indoor medium/high grip black carpet. The recommended body of choice by my local track is the CRC low downforce black art body. I have tried 2 of them and find the quality is just not good. I got the ultralight versions, but they were so thin on the sides that when I painted them they curled up and are basically unusable. Who else makes a good low drag body? The CRC body has the correct aero, but horrible quality.

Let me know when you find a better option. Until then -- stock up!

I think the ultra-lights are too thin. Arguably they aren't great for aero either as a panel flapping in the wind causes loads of drag compared to a rigid panel.

As an alternative, this Bitty LSM19 seems pretty good. It even looks okay, but be warned it sits super low on the car.

Drywall tape and shoo Go will stiffen those bodies up.

I would think this would add way too much weight. But thanks for the response.
