I know you can mis and match batteries in the snowblower.  Are there any advatages or disadvatages to mixing a 7.5 and a 5.0 vs dual 5.0?

I bought the self propelling mower with 7.5 battery.  

I was thinking of buying the powerhead + trimmer/edger which comes with a 5.0 battery.  So I was thinking of saving a bit and buying the snowblower kit without batteries and using those batteries. 

But if there are any disadvantages to running 7.5 with a 5.0 then I'll just get the snow blower kit with dual 5.0 and get the powerhead trimmer/edger without batteries.

No disadvantages at all. As long as both batteries are 4Ah or larger you’re good to go. 7.5+5=12.5, which means 25% more run time than two 5Ah batteries.
