So, last week I dropped my twist on the ground breaking the battery, tried to fix it (drunk) mmmm hmmm...........bad idea........Ordered a replacement, also (drunk) mmm hmmm........bad idea......and I messed up and ordered the non variable voltage version. So......big question, what is the difference? I kept my twist sitting at 4.0V and was very happy with that set up, what can I expect this new one to be like? Anyone tried both, did I mess up real bad or just a little bad lol? Comments GREATLY appreciated!!!
