I would keep them cells if not. They remove weight more than add.
What about the evo packs? The have a good discharge rating.

Actually no, the batteries I'm using are filled with helium and do reduce the weight. ;)

And now Squee's response post makes sense. I didn't catch that before. Doh!

Seriously: Yeah, the weights are reversed. Are these the EVO cells you are talking about? The GP3300 cells I'm currently using work perfectly fine if a bit heavy.

i think squee is talking about these http://www.flightpower.co.uk/

Oh.

The only large single 5s pack that would fit length-wise is the 2500 pack, which is too low in capacity. Paralleling them would be too wide.

When I made the V2 Revo, I figured I would be able to find a decent battery solution to I was wrong. Oh well.

To summarize what I'm looking for:
- Weight = 500g-600g.
- Capacity = 4-6Ah.
- Continuous discharge of >= 80A.
- Fits into an area 6.25" long (160mm), by 2" wide (50.8mm) by 2" high (50.8mm). I remeasured the length just to be sure.

i think these will fit, but they are expensive! and :004: 30c discharge:004:

Sorry:o , just curious what did you buy instead?

[squeeforever]

Nothing :mad:1 ...

are the tanics good batteries? are they worth the price?( i can get them cheaper, my dad works at my lhs)...

[squeeforever]

Yea, there great batteries, but it depends on the price...

[BrianG]

Wow, those are expensive! And they are "on sale" for "only" $310 right now. Other than the price (which I didn't specify in my list of "wants") they look like they are the way to go.

:sigh: Off to ebay to sell stuff I guess...

[BrianG]

Yeah, those are close.

So, it looks like I do have some choices after all:

- A 2s and 3s set of the Apogee LiMn packs: 3800mAh, 20C cont, 586g, 139mmX42mmX46mm for $250
- A 5s, 5Ah, 595g, 155mmX44mmX43mm tanicpack for $310
- A 5s, 5Ah, 635g, 162mmX49mmX38mm PolyRC pack from cheapbatterypacks for $310
- A 5s, 8Ah, 850g, 166mmX59mmX40mm pack made up from TrueRC for $175

You really can’t beat the price of the TrueRc lipo…..


I say get the TrueRc because of the price or…
Go for the gold and get the tanic

[MetalMan]

Just FYI, the Tanic and Poly RC packs should be the same due to the same cell origin - Enerland. If you were to get that pack, get the Tanic version, as Tanic is well known for customer service (not that Cheap Battery Packs isn't, it's just that I've seen Tanic's CS).

[BrianG]

Yeah, the TrueRC is hard to beat for the capacity/price. But the weight is just about as heavy as the NiMHs I'm using. The Tanic pack is much lighter and still has 5Ah with good discharge rates.

Now to come up with cash. I still have a BK 12020 for sale (hint hint). ;)
