Lipo Battery Suppier

Hi

I have searched the forums but cannot find the answer, does anyone know of a rechargeable Lipo battery supplier that is trustworthy as a Google search provides companies from China with little information about their reputation ? We would like the battery to be similar to the one below and can be from anywhere worldwide.

Thanks

It looks the same as the batteries in my model helicopters but mine are 1/10th the size and mAh rating. I get replacements at my local hobby store. They have many batteries much larger than mine but usually they have more than one cell. I buy two American brands for my larger radio controlled model airplanes, Thunder Power and E-flite.
