if you need replacement there is a shop at SIM LIM selling the 18650 Samsungs.
just an evic vtc mini, about 4 months, about there...18650s like the VTC4 are designed to last about 300 charge/discharge cycles before they lose a significant amount of their capacity and their amp limit. If you stress the battery by exceeding the CDR on a regular basis then this can be significantly less.
What is your setup and how long have you had your VTC4?
gotcha...Thanks for your help!!TCR should be more efficient not less.
As I said it it may just be your perception of the cells performance, a bad cell, or something else like errant Martian radar beams. If you are really concerned, buy a Samsung or an LG as they better suit your watt range.
Hi u guys know where i can get those LG batteries and how much it costs. TIA
