That 300W test is getting better...about 93% of capacity while staying well above 3v/cell... but we really need closer to 700W to see if they hold up to their 30C discharge. Otherwise they should be more realistically rated as only 15C cells.

I want to see what voltage they can maintain at 66A continuous discharge!

I'm not picking on Haiyan here... there is probably no cell-brand out there which can do what its typically optimistic C-rating would suggest it should be able to do!

Sorry I'm not that technical. I can only provide subjective opinion. I was specially pleased with the customer support side. Happy flying!

I received two 3S, 2200mah, 40C lipos Saturday. Very fast shipping. I shared them with several members at our club. Everyone, including myself was pleased with the results. I plan to order a couple of 4-cells to see how they perform. I am sure that if there are any problems, they will be posted on the forum. Also, the warehouse is in Nevada (USA)

Pack only slightly warm.
What was the voltage of tha pack under this load and I'm guessing around only 30amps so hardly close to the rated capacity.

Good to point that out Red, we really don't need another "labeler".

Eric, I see that the smaller packs have a XT60 connector on them. Is that a genuine XT60 manufactured by HeXTronic?

Do you also manufacture the cells for the Turnigy brand of lipo's? I use Turnigy batteries, and if you are manufacturing them, I might as well just buy them direct. Thought I would ask.

I do large scale electric planes, and it should be interesting to see how these ring out for sport and extreme use (large scale EDF jets, for instance). The "jet" guys will definitely give you some "real world" numbers, and let you know if these are up to the task or not. I'm interested in larger size packs (3S-6S 5000 mAh +), I hope the larger sizes are in the works.

The "Battery Finder" on your website is very helpful. I am looking forward to testing some of these smaller and larger cells with my PL8 using the high power regenerative discharge and graphing features. I have hundreds of lipos and it is about time to start replacing them. I am considering these Haiyin cells.

They won't sell many batteries if they don't fix their snail speed website...

Prices seem a bit high also, may be worth it if the batteries are better than the run of the mill.

I have been passing my two 3S, 2200mah, 40C lipos around the club members for the last two weekends. They have been used in EDFs & various prop planes.
Everyone likes their performance so far. I would recommend these lipos.

Great, keep it up!

Get lots of cycles on those batteries. Lets see how they perform after 25 to 100 cycles. And lets see how the batteries physically hold up as well.

Since you are providing cells for drag racer how about some larger format cells like 10ah or even 20ah hi c cells!

Any like that in planning.
