Default Best Battery for 17.5 TC

Iím getting back into TC racing. I see there are now HV 8000+ lipos. Are these necessary for the 17.5 class. What is a good trade off between weight and capacity? 7000? 6000?

also, how are the protek lipos? I really like the one I have in my 2wd buggy.

Never got more than 2 each cell high or low amp charge, usually less than 3 total IR. I have several others that are 5600 and 5800 from other vendors, and the performance of the R1 6000 on the track doesn't drop off at all by the 8 minute mark whereas the others do at the 6ish minute mark in a 17.5 TC. In my USGT and VTA cars, there's no difference in performance due to the lower draw. YMMV

Is that on a normal charge/discharge cycle or 40/40? By normal I mean 10/10 or even 20/20.

Typically you would use 7000+ batteries on large tracks (140+ ft) where you're on throttle the majority of the time. Most of these are outdoor tracks. For indoor, mainly carpet racing, you would run smaller capacity packs.

Nobody runs packs that large where I am on our larger tracks. They're usually in the 5000 to 6500 range.

I tried Sunpadow, I had a 6600mah Black Phantom pack for TC and a 6000mah Gold pack for my Vta Car. Charged @ 20 amps on both, discharged and charged again. 1.0 IR per cell on my Icharger for the 6000 pack and 1.1/1.2 on the 6600 pack. I was happy with them

That is a impressive IR. I for sure need to buy a new battery. As bad as I hate to say, the Trinity white carbon batteries are the best numbers I have came across in a long time.

Depends on track and car. Light car that needs weight and on large track, 8000+, keeps voltage higher longer in the cycle. Heavy car stick with 6000ish to keep balance in check. Tight tracks, i'd recommend any of the 5000-6000 LCG batteries. Personally i run IP 8400s in 17.5-21.5 classes on large track.
