I'm sure it works fine. I'm just relating all the advice I've read on the Wisec DNA200 and RX200 regarding batteries, i.e. use 3 new ones of the same brand and model, (high quality goes without saying

), use them only in that device, and always charge them together in a separate charger. I'm sure this is just to maximize the longevity and performance of the trio.
