I've been running 65-110c packs in my 48", and 78" planes, but I've found due to the stupid high KV rating of the 40/16/500 torque VI, and the MKII, a Quality 25-40c pack provides more than enough sustained power..

Thanks for all the replies guys! A lot of good choices. Opinions on the Sky Lipos?

Doc, those are some nice batteries! How's the weight with them? I found some Gens 4000's that are 1oz more than yours, but thinking I should be going with something lighter?
I'll let you know on the deadband on these Hitecs on both planes when I get a chance to check them out.

Thanks,
Rick

Thunder Power's website says 620 grams, but can that possibly be right?

I got these packs by accident, but it turns out the added capacity comes in handy and I can fly it really, really hard without running out of battery.

I think I would go with the lightest pack I could while still getting acceptable run time. 3300s seems to be fine with most folks.

I do not like 30c sky lipos. I just picked up a thunder power to compare to my revolectix. The Gens Ace 25c are great when they mark a 60c as a 25C, which they seem to do most of the time. Search rcgroups for the revolectrix....good battery great service in my experience. Somebody just did a restive test against a lot of other batteries, and the revolectix did very well against the thunder power.

I like these 3600's for the extra. 4000's are a bit to heavy IMO.. Don't forget the original spec battery was a 3300.. The 3600s always balance between a quarter, and half inch from the wing tube. I'm sure if you go with four thousands, you'll be adding nose wait.. You never want to add weight unless you absolutely have to, and I don't feel extended flights is a good reason..

as for me, the extra flies better the lighter it is. and 5min flighttime is allright.
the desire power 6s 3300 35c is only 485g.
the 6s 4200 35c is 585g.
i have 2 extras, in one i fly the 3300er with the rudderservo in front and the other one i use the 4200 with the servo in the back.

the 100g is a difference in performance.
as for the mxs it doesnt matter.

Agreed.. Around 500-550g is the sweet spot..The MXS is a different bird..

I will be upgrading to 4000's but I'll only be running them in the MXS. Ill still be running 3600's in the Extra.

One of the things I had to adjust to with the 60" Extra was how much floatier flying it is than the 48" planes I am used to. Even with 6s 3850 packs, the plane still feels pretty light to me. I think for my new round of packs I will try the 3300, just to get the balance dead on.

I love my 60" extra so much I've been thinking of getting one of the 48" planes. Is one of the 48"ers better than the other? Also I have an e-flight power 32 lying around, would this be too much for one of these 48" planes?

The 48" extra, and 48" laser are my two favorite park planes! I've been flying a laser lately, but plan on getting my fourth 48" Extra before spring..Incredible plane!

Voting time The used batteries I tried to buy didn't work out, the Gens Ace are out of stock and I saw the Haiyin link, but don't like the 2s charge rate.
I'm thinking it's between these two. What do you guys think about these? Both mentioned in this thread, just trying to decide

I have two of these and 4 Skylipo 40C 6s3300 and too be honest I cannot tell the difference in the air nor on my charger between the Nanotech and skys. Actually the Nano's come down cooler to touch after the same flight times.

I think the Revo 60c 6s5000 might be a little big for this plane?
