Just wondering if anyone have used these on their Belt CP before?

It has a good review, it says constant discharge of 25C and max burst is 35C, is that gonna be ok for my stock brushless system on my heli or will it burn out the motor and ESC?

Good price heavy as a rock 40g heavier than similar packs. Like I said before don't get hung up on C-rating your not gonna pull that current anyway 15C is fine even for 3D flying.

Havent had time to study that website though a lot of them are just e-commerce sites and will charge you hong kong shipping.

Butters,
The "C" rating on a Lipo packs only refers to what current the pack is capable of discharging at. Your motor and ESC will only pull the current needed from the battery, which in this case is not the full stated discharge the battery can withstand. Your ESC will only be affected by the amperage the motor is pulling. With Lipos you want to make sure the battery is capalbe of discharging at a high enough amperage. A 2000mAh pack that is rated at 20C is capable of discharging at 40 amps. With a brushless HB King V2, you are most likely only going to pull 17-18 amps max. So you would be fine, as Tyran said with a 15c pack (30 amps).

It's true! Practice does make perfect. I crash better than anyone I know!

I also only use 15c packs and they seem to handle alot of abuse. I think over dischargeing a li-po is the worse thing you can do to Li-PO. It's funny, back in the days before li-pos I would use Ni-Cads and because they would build up memory you had to discharge them ALL the way down to get a good charge. Then when Li-Po's came out it was DON"T drain them all the way down.
I don't know about that peticular battery but sometimes you take a chance and you win. Sometimes you go with a name brand and ya get a dud, ya never really know till you get there. In the words of the Great Forest Gump-- Life is like a box of chocolates--Ya never know what your gonna get !

I switch to air thunder packs this year and I'm very happy with them. They don't puff or loose power during the flight and the best part is you can fly til the heli falls from the heavens and just recharge them..... Plus they are cheap too.....
