I recommend this product
Dualsky VR Pro Duo
It works great but the instructions is bad and tech / customer support is unreachable! It only support LiPo battery and does not seem to work with liIon or LiFe batteries. Maybe it will but I can’t find out how to set the options( if there is any!), it is not in the instructions that came with the unit! Need to email Dualsky to get clarification!

It’s a good product but could not find any tech support to try to resolve a question. It will only work with LiPo battery and not LiFe or LiIon batteries.
