They are cheap (as far as I can see), because Hong Kong has an artificially low exchange rate to the US dollar. And they are not at the top end of the performance scale. And they do not have high marketing costs. I have used these batteries with no problems. I have even shorted them by accident

. But they did not blow up and they charged fine after. And I’m sure there are other people out there who are using them on the weekends and have also found that they work perfectly fine. If I was running a model shop I would look into speaking to the manufacture or even one of the Hong Kong distributers and see if some sort of arrangement could be made with becoming the UK distributer for these cells, and see if we cannot bring down the cost of racing a bit.
