FWIW, I've bought quite a lot of stuff from this manufacturer (ETT, in Thailand, I think), and they are really reasonable quality boards. Heavy copper, good through-plating, and pretty solid.
The only glitch I can see is that all their non-English gear comes only with Thai instructions and code examples. But if you're modifying an existing codebase, that won't be an issue. Just clear out the downloader in the supplied chip and flash the V300 modified code.
Good sized board, too. That's about the format I usually make, but I use linear regs and so on, so it's not as efficient.
[EDIT] The first thing I'd do is get rid of the bridge rectifier, and just connect up to the battery. They're just wasting power and dropping your working battery voltage. Just a thought!
