Sony VTC6A Battery Review
Based on my testing, the following tests indicate the approximate ratings for these batteries. Be aware that batteries from brands like Samsung, Sanyo, LG, Panasonic, or Sony batteries can undergo alterations at any time. This variability is one of the risks associated with using "rewrapped" batteries from alternative manufacturers. Therefore, it is crucial to thoroughly research any 18650 batteries under consideration before making a purchase.
Important Safety Information
Misusing or mishandling lithium-ion batteries can significantly threaten personal safety and property. These batteries are intended exclusively for use within a safeguarded battery pack, such as the Sony VTC6 battery. Never exceed the battery's current rating; always maintain the plastic wrap and top insulating ring optimally.
Testing batteries at their maximum limits is hazardous and should never be attempted by individuals who have not extensively studied the associated risks, comprehended the potential dangers, possessed the appropriate equipment, and implemented all necessary safety measures.
If a battery only displays a single number denoting its current rating or exclusively states "max," assume it is rated at that specific current level for any form of discharge, including continuous release.
Sony VTC6A Batteries Overview
Initial Testing and Availability
Gypsy Vapes gave me two pre-production or early-production samples of the Sony VTC6A 18650 batteries for testing. They informed me that these batteries will be available in a few months, possibly by the end of the year. I need information regarding stock availability or future availability dates.
I conducted these tests due to numerous requests and to inform vendors about their performance. I will retest these batteries when full production quantities become available, as Sony may make minor alterations to the cell's performance before then.
Performance
The two VTC6A samples I tested outperformed the VTC6. While they exhibited a slightly stronger initial discharge than the VTC6, the Sony VTC6A battery surpassed the VTC5A for the remainder of the release, particularly at higher current levels. This is undoubtedly an exceptional battery.
At a continuous discharge of 20A, the Sony VTC6A battery operates at the same temperature as the VTC6 at 15A. Sony will likely assign a current rating to the VTC6A approximately 5A higher than the VTC6, suggesting a continuous current rating of 20A with temperature-limited operation above that point. My preliminary estimation for the VTC6A's current rating is 20A, up to 25A if the temperature remains below 80°C. However, this estimation may change as I acquire additional knowledge about this battery cell.
Capacity
The VTC6A batteries I tested provided 2892mAh and 3008mAh at 0.5A, showing a more significant variation in cell-to-cell capacities than typical Sony cells. The reason behind this discrepancy is still unknown. It is possible for the capacity to experience slight alterations before the batteries become available in total production quantities. Nevertheless, I estimate the VTC6A's rating to be a minimum of 2900mAh and a typical value of 3000mAh.
Conclusion
While the VTC6A shows excellent promise and superior performance compared to its predecessors, waiting for the final production units and updated ratings from Sony is essential. Always prioritize safety and thorough research when handling and purchasing lithium-ion batteries.
