Biggest lipo for Belt-cp

[sortegon]

What's the biggest lipo you recomend for the Belt-cp???
Im looking for longer flying times... what about a 3500mAh?? Will it fit?? Will it fly??
thanks!!

well that sounds like a big,powerful pack !sure its heavy n longer rite?perhaps i mite try that size too!

The Belt will probably lift that pack all right, but it will be a pig to fly. You're going to run into serious CG problems, and all that extra weight is not going to make it perform any better.

So far my favorite is the Flightpower Evolite V2 2500 mAh... Better capacity, 20C discharge, and weighs about the same as the Esky 2100. Balances the helicopter perfectly.

I'm looking for an upgrade battery that sounds perfect. Where'd you get it?

Thanks folks!! I think I´ll go for the 2500mAh lipo pack, how many minutes can I expect to get from it??
Usually I fly 5 min. with the original 1800 mAh pack before it starts loosing power.

Also, do you recomend to get another lipo charger?? Or just keep the one that came with the belt??

Another question... I just ordered a switching BEC to power my spektrum receiver... and because its more efficient... I could expect to loose less energy in heat... so... longer flying times... am I right???

thanks!!!

With a good setup you van get 12 to 15 min of hover depending on the weather conditions

I just found two flightpower 2500mAh packs? Evolite 20c and Evo25c. The last one.. is just a little bigger and heavier... but just a little.
Anyone has tried it the evo 25c ???

Don't fly until the LiPo can't supply enough power... that'll kill the pack quickly. I think you could easily get over ten minutes out of the 2500, but it's best to stay on the conservative side. A cheap LiPo alarm will tell you when it's time to land or risk damage to the pack - and they trigger long before the Esky ESC's low voltage cutoff does.

You should never discharge a LiPo more than 80%, so the best thing you can do for your expensive batteries is to get a decent charger and see how much it will put back after the flight. For example, I just tested one of these (http://www.hobbycity.com/hobbycity/store/uh_viewItem.asp?idProduct=6451&Product_Name=ABF_2200mAh_11.1v_18-23C_Lipoly) $20 packs on the MD500, and my Cellpro 4S put back 1700 mAh after an eight-minute flight that ended when the LiPo alarm first blinked. That's right on the nose for 80% discharge, so now I have my flight timer set for seven minutes and I know the alarm will keep me safe.

The Evo25 line is good for higher discharge rates, which you'll never see on a Belt CP. The pack chemistry needed for the higher C rating also means the pack won't last quite as long and the heavier weight means you'll get slightly less flight time out of it. I'd get one for a souped-up T-Rex, but 45 Amps is plenty for a 25 A ESC :D

I totally agree with another_finn .
I have set my timer for 10 mins and I fly the 25c 2170 mA flightpower, just check regulary the the volts for proper balancing, doing so will keep your batts in good health
