Going for some better batteries

I am planning a new adventure and power management is a top concern  after taking a look at the days off the grid that I will be experiencing and not having a whole lot of luck going down the solar charger route, I determined that a half dozen batteries will get me up and down Mt. Kilimanjaro.  The problem, the canon OEM batteries are expensive,  as in  ridiculous!  A few colleagues have looked at many of the 3rd party manufacturers and one seems to stand up to scrutiny,  batteries from Wasabi Power.
