Never had an issue with maxamps quality of product. Had a comunication issue that they went overboard to resolve. They are excellent people to deal with .

But true-rc has the same quality, if not better, lipo cells for half the price. I've run alot of different brands, maxamps true-rc , he-cell, enerland, e-flight,orion , core, and a e-fuel.Bang for the buck true-rc has been a best buy in my opinion. Now that they have a hard case, once it gets approved I'll be running that.
