Is there a good alternative to the Sony VTC4?
Even though the Sony VTC4 is still in production and genuine ones are available there are vapers who are uncomfortable taking a chance at buying counterfeit Sony batteries. Could the 22A-25A rated LG HD2, HD2C, and HD4 be as good as the Sony VTC4? Let's find out.
In the graphs below I discharged all four batteries at 10A-20A-30A continuous and 30A pulsed. In the constant current graph all of them ran at about the same voltage at 10A continuous but the HD2C lasted a bit longer. At 20A and 30A continuous the HD2C ran at a higher voltage (hit harder) than the others and still lasted longer. The VTC4 didn't beat the HD2C but it performed a bit better than the HD2 and HD4.
In the 30A pulse current graph the HD2C lasted a bit longer than the rest with the VTC4 and HD4 about tied for second place. While the HD2C ran at a slightly higher voltage than the others when pulsed they were all very close in performance and I don't think you'd see a difference in actual use.
So, is there a good alternative to the VTC4?
Yes, the LG HD2C.
It not only runs at a slightly higher voltage but lasts a bit longer too. The LG HD4 is a close second in these tests and is roughly equivalent to the VTC4 for vaping at up to about 25A-30A/100W.
