H1 Battary issue
 

I have 4 long duration Sony infolithium NP F battery that I used to use on my Canon XL1 by stitching the part of the canon AC power ext. adaptor to guts rippedout sony batt. charger. It works perfecty on my xl1, and have been using this rig for the last few years. I have tested this on the H1 and it works as the voltage output is the same, but should I do this on my xl H1? Any not of caution from the experts?
