Lol ya im a wicked tinkerer haha. I love messing around with things. I cant think of anything i took apart n put back together and it didnt work afterwards. Ive been ripping cars apart and putting them back together for awhile now as well. Projects keep me out of trouble...kinda lol.
If it looked like it was too much involved in changing the osub to use replaceable batteries, i wouldn't attempt it, but it just looks real easy haha. Ill def do more research before i actually do it, but i dont see it being a problem, yet. I got it...hmmm... prob around January maybe? So i still got awhile to go before its out of warranty. Im actually quite surprised that your's have lasted so long. I have no idea what the life expectancy is on internal battery mods tho. I just look it like anything else that uses rechargeable batteries, cell phones, my cornwell drop light which didnt last long before it stopped turning on, i thought it was a problem with the switch since it seemed the switch was acting up, especially when the charge got low, so i replaced the switch and the damn thing wont turn on. Seems like the internal battery crapped out, and i never really charged it that many times. The battery lasted a really long time between charges. Now it seems it wont take a charge or something. Only a couple years old, maybe 10 charges, and it no longer works. Was pretty expensive led drop/work light too. So between cell phones, the light, cordless tools, and various other battery powered things that seem to loose their battery life and not last long between charges and not taking or holding a charge after within a year or two, i didnt expect these internal battery mods to last that long.
I really hope smok does release the g150 and spirals plus kit with interchangeable batteries, ill be all ovef that kit lol. Thats the only thing holding me back from pulling the trigger on it. Aside from the 200w snow wolf i may buy off a friend, my next mod will be a mech. I was looking at those diy mech mod kits, if they had cooler cases, id prob get one of those. Ive been catching myself looking at things like, "hmmmmm....can i turn that into a mod?" lol. Im more into box mods than tube mods.
