Almost any 3s LiPo pack is going to improve your flight times. I use a 3s4p 8200mah from Thunderpower and get 20+ minutes from it. If you go with a 3s3p at around 6000 mah's you should have plenty of flight time and less battery weight than you have now, so performance should be sweet. If you go LiPO, you'll also be able to reduce your pinion size to around 17 with the B/C 40-8L motor.

There are a couple of brands available, but Thunderpower is probably the best known (it's what I've been using). For the VE with the Hacker motor, I'd recommend the TP6000-3s3pSHD.

Just as a reminder, LiPO requires a special charger type and you can't (shouldn't) use a charger that is not rated for LiPO. If you do, you run a high risk of pack damage or possible fire.

Best Charger
When I upgraded to Li-Poly batteries I ordered the Schulze 330d charger a recomended by Thunder Power for their Batteries. It is pretty expensive but is by far the best all-round charger I have ever used. The newer ones with V8.00 software charge Li-Poly and all other currently available battery types and charge at up to 5.5 Amps.

It is available from Thunder Power or Schulze.

Regard, Alan

I am running a 3s4P 8000 mAh Thunder Power battery. With my setup (Hacker C40-8L, Castle Creations phoenix 45 ESC, ultimate BEC, HS85 & 81 servos, 15 tooth pinion, carbon fiber frames, micro V canopy, carbon fiber main blades) I am getting 32 - 34 minuet fights. The last minuet of flight is as good as the first minuet.

As a comparison, with a 10 cell Nickle-Metal-Hydride pack I am getting 11 - 12 minuets.

Lightening goes a long way to extending flight time.

One thing about these large capicity LiPO batteries is they take a long time to charge with a lower cost, lower amp rate charger. I have a Triton charger, this puts out a max of 2.5 amps for Li-PO so charges take + 3 hours.

Thunder Power has them right here. Just scroll down until you get to the 3s4p packs and it's there. If I were buying a new pack, I'd still look at the 3s3p instead...it's lighter (better performance from the heli), has the same voltage and at 6000mah it should fly for a good 18-20 minutes using Hoffmans config.

Hoffman's correct by the way. Reducing weight will go a long way toward improving performance and duration. The other mod that I HIGHLY recommend with the brushless/lipo combination is the tailboom stretch. It allows you to run 470mm blades and really gives the VE the sort of disc loading that makes it perform great. It's also EASY to do. Just grab a Venture boom, cut it down to 22 1/4 inches, replace the stock belt with an ECO16 belt, make a new T/R pushrod, bolt on new blades and you're in business. A huge performance gain !!

Lithiums are great for the Voyager for duration and Light weight but If joey is just learning to fly a heli stick with the nimh packs.You can get 8 minutes with the right setup and 10 cell packs and when you crash you don'y have to worry about a $50.00 10 cell pack compared to a $250.00 lithium pack.
