@GhostRider17 .The Aspire battery i can't offer any help but if they work well so far i doubt there will be anything wrong or to worry about not sure if you are sticking with Aspire batteries as your using an aspire mod, if so there is no need the samsung and LG batteries are of similar stats but available cheaper. Best to buy 20amp cdr don't think oh 3500mah 10 amps as they won't be powerful enough
Next time you need batteries, save yourself some money and go to one of these vendors linked below, The Samsung 25r are about the same as the aspire batteries both ampage and mah.
The samsung 30Q gives more runtime but slightly less amps i rub samsung 30q's in a couple of my dna 166w mods and they are fine being dual battery even at 100 watts. LG HG2 is similar to 30Q, sadly the LG He4 is no longer available anywhere it was about the same as the aspire battery
Both sites have money off codes available and 18650uk offer free shipping to boot. Both vendors are excellent and both named Ben.
