Excellent batteries, Mine show on the scale 278 grams. After first charge at 1C (2.2amps) all cells show 4.20v. I'm using these in an Edge 540 Balsa. These balance out much better when you can fit a wider/thinner battery in your compartment. All cells after many charges/discharges show 4.20 or 4.19v when fully charged. I'm very happy with these!!

I've been using this in the Seavixen and the Vampire. They fit great and give plenty of flight times.

Update....
Batteries have lost a lot of low-end power and I'm only able to pull about 520-540 watts (colder air too, which should make it higher watt readings) ...roughly 60 -70 cycles and I only run them down to about 50-60pcnt (put 1000-1200ma back into them on balance charges). Charge at about 1.3c (3.3 amps). Still climbs from hover, but very noticeable loss in performance from when the were new even to the point where servos seem slower (HS-65MG's) and things like pop-tops are a bit less impressive.

So in my experience, they're not a great, but not a horrible battery for the price ...I wouldn't expect more than 1 season out of them for 3D flying (the performance loss was noticeable within about 3 months of use).
The 3000's that I'm using in my e-flite CZ Yak54 only have 20-25 cycles (if that) and already the stock e-flite 2800 is out performing them. CZ Yak has 60amp(?) stock ESC and 1050kv(?) stock motor and weighs in closer to 4lbs.

Great so far. Only about 4-5 cycles on them (6 of them). I put Deans on them and am using them in a E.F. 48" Edge 540T-EXP (with the power combo 2614/820 Torque and 45A Airboss ESC)....12x6E APC prop.

Measured with watt meter today... I got right around 640 watts ...on a plane that's just over 2lbs ....nice! (initial spike was about 680 then settled in the 635-665 watts area with a few run-ups from idle to wide open)



Hopefully they will last well. Only (minor) downer is that they won't fit in beyond the firewall (into engine mount box) unless you put them on their sides (otherwise slight tail-heavy cg) ...no biggie.

I received this lipo, i cant reach the way to load it completely. One of the cells is defective, and the voltage cant exceed up to 3.93v. We only can enjoy the warranty, returning back the defective articles, but with the weight of the battery is not profitable to return it back. HK should test completely the batteries before sending. Now, i will have to maintain here my new and defective lipo. What would you do...?
