Can you provide an example of a battery in the same form-factor with a higher current capacity? I keep my eyes open pretty well and haven't seen one in that form factor. I've seen a couple advertised that way, but when I put 'em on the test harness they end up being far less than claimed.
V4L pays well to own technology advancements. Believe me they are interested in keeping on top of it, even if it doesn't make financial
sense to build and stock it today.
