3,Samsung INR 18650-30Q: 15 A – 3,000 mAh
Onto the best 18650 batteries, the Samsung INR 18650-30Q has a slightly better than average amp limit – offering up to 15 A continuous discharge – and an excellent capacity of 3,000 mAh. This uses nickel chemistry (indicated by the “N” in the name), and testing suggests it actually performs reasonably well at 20 A, although it’s better to stick to the 15 A max recommendation for safety purposes.
2,LG INR 18650HG2: 20 A – 3,000 mAh
Also offering a 20 A maximum continuous discharge but providing 3,000 mAh capacity, the LG INR18650 HG2 is up there with the best vaping batteries for sub-ohming. The only reason this isn’t placed above the HE2 and HE4 is that initial testing from Kidney Puncher suggests a fairly poor performance, dropping to around 2,100 mAh when tested under vaping-like conditions on a 0.2 ohm coil (meaning 21 A at the full 4.2 V). Still a great option for the amp limit alone, though.
1,LG 18650 HE2/HE4: 20 A – 2,500 mAh
The HE2 and HE4 hybrid IMR 18650 batteries from LG both have the same core specs, offering a 20 A continuous discharge limit and 2,500 mAh capacities. The (yellow) HE4 is the newer model (and is actually called the LG DBHE41865), and shows good performance in tests at 20 A, although the capacity drops considerably when tested under the (not recommended) amp-load of 30 A. If you can’t find the HE4, though, the (red) HE2 is still a very dependable battery and may be easier to findin stock. Kidney Puncher claims that they’ve seen tests where the HE2 handles much higher currents, but available tests show a notable capacity and voltage drop when tested at 30 A. As always, it’s best to stay within the battery’s official limits.
