Do you know the CDR of that battery? And the amp draw using that coil?

If you're using a mech those are two basic details you should know. And if you know those two details you can answer the question yourself.

Also, you will see in the last cell of the chart, vendors Mooch considers "reputable" meaning they sell authentic batteries only. Some of the newer 27-- chemistry it may be a bit harder to find what you need, but for Sony, any of the battery manufacturers listed should have what you need. It can be very hard to spot fakes and counterfeits and in a mech, especially, you really need to know that your battery is authentic. The good news on that is the good manufacturers tend to have reasonable prices, often less than in other less reputable places, and most process and ship quickly.

If you aren't in the US, you might try some of the international forums to figure out a reputable supplier Best of luck and welcome :)

Amp draw is 24.71 but im still not sure of CDR of VTC5 because when i check it online one site says 20a and the other says 30a.
This is one of those "inconvenient truths" that Battery Mooch speaks about. There is so much misinformation out there about battery ratings between battery manufacturers, battery suppliers, and vendors its extremely difficult to know who or what to believe. This is the price that we pay for an industry (batteries) that is not regulated.

Here on ECF, and gaining notoriety worldwide, we trust Mooch. He's an independent battery tester who exposes companies and suppliers who lie about the specifications of batteries.



Even some of the so-called "trusted" suppliers will advertise the wrong specs. Li-ion Wholesale is frequently mentioned as a trusted supplier, but they list the SonyVTC5A as a 30 - 35 amp battery. Mooch says its just a 25 amp battery:

SONY VTC5A 30A-35A 2500MAH FLAT TOP 18650 BATTERY - GENUINE - WHOLESALE DISCOUNT

Mooch - Sony VTC5A 2500mAh 18650 Bench Test Results...a fantastic 25A battery!

SONY VTC4 30A 2100MAH FLAT TOP 18650 BATTERY - GENUINE - WHOLESALE DISCOUNT


Mooch - Sony VTC4 2000mAh 18650 Retest Results...a great 23A 2100mAh battery

So, which source are you going to believe? I choose to lean to the side of caution and safety. After all, we use these batteries in our hand and next to our face. Also keep in mind that as vapers we are using these batteries that were designed to be used only in protected battery packs in the electric auto and mobile power tool industry, not designed to be used as a stand alone battery in a high current battery device.

So i should change my coils, thank you guys for help!
Yes, you should change your build to something under your current amp draw of 24.71 amps. Your VTC5 has a 20 amp continuous discharge rate, so you're over its amp limit.

Go with the lower number if you are not sure. I am loyal to Samsung 25Rs for 18650 tube mechs. Does the Vgod take 20700? That would be ideal. I have Ijoy "40A" for my Pulse Mod. They are great! I hear they are actually 30A though. Those hit real hard.
