    These three batteries all have the same ratings, 30A and 1500mAh, so I decided to do a shootout to see if there was a clear winner between them. Pulsed discharges at 30A and 50A were done (5 secs on/30 secs off) down to 2.5V. All three were quite close in performance but there were some slight differences that can be noted:
    • The HB2 ran a touch longer than the HB4 which ran a touch longer than the HB6.
    • The HB4 had a slightly higher voltage at both 30A and 50A but the HB2 was very close for most of the discharge.
    • The HB6 had a slightly lower voltage than the other two at both discharge current levels.
    • There was only a 5°C max difference between any of the batteries for both the 30A and 50A pulsed discharges.
    Bottom Line
    The results are close and the HB2 and HB4 are almost identical. The HB6 trails by a little but is still a very good battery. The results are close enough that you might not see a difference between any of them when vaping. There is some conjecture that all three might be the same battery, just manufactured for different customers so they have different wraps and model numbers.

    I took a closer look at these.

    My HB2's and HB6's are absolutely identical in appearance. My HB4's are a tiny bit different in appearance but only when using a 5x magnifier. They very well could all be the same cell.
