The kick , just adds the wattage factor , into the mix . with no way of really knowing , what you have . Skip it and just use voltage . If you get some sort of telescoping device , you can use different size , and voltage
batteries . The 2 cent chip , If your that paranoid about battery problems , go ahead . Waste of money , as far as I'm concerned . Been at this over two years , and have never had a battery problem . Just be dilligent on charging , and using only the "safe"
batteries , and you should be fine . If you want to use Vw , then I would suggest a Vamo , or a
sigelei Zmax . Good Luck .
