Sony VTC6 Battery 18650 3000mAh 15A Flat Top
The Sony VTC6 battery review provided below indicates the estimated ratings of these batteries at the time of testing. It is important to note that batteries not manufactured by Samsung, Sony, LG, Panasonic, or Sanyo can change anytime. This highlights one of the risks of using "rewrapped" batteries from other manufacturers. Therefore, thorough research is strongly recommended before purchasing any battery.
Safety First
Improper handling or misusing lithium-ion batteries can pose significant risks to personal safety and property. These batteries should only be used within a protected battery pack and must never exceed their continuous current rating. Keeping the plastic wrap and top insulating ring in perfect condition is crucial to ensure safety.
Testing batteries at their maximum limits is hazardous and should only be undertaken by individuals who have thoroughly researched the associated risks, fully understand the potential dangers, possess the necessary equipment, and have implemented appropriate safety measures.
Ratings
Please note that the ratings in my rating tables are subject to change. That's due to the emergence of different grade cells in the market or the prevalence of counterfeit products. Therefore, always assume that the ratings provided in the tables are temporary and may be updated. Ensure you have the latest version of the tables before making any battery purchase.
If a battery only displays one unspecified current rating or solely states "max," it should be assumed that it is rated at that specific current level for any type of discharge, including continuous release.
Sony VTC6 Battery Summary
This serves as a retest of the highest-performing Sony VTC6 battery. Assigning accurate ratings to this battery and the Samsung 30Q for these retests has proven challenging.
Sony designates a continuous current rating of 15A for this cell but permits temperature-limited operation above that level. Like the Sony VTC4 battery and Sony VTC5 battery, It is possible to operate the battery at levels above 15A, but only until a specific temperature, 80°C, is reached, after which the discharge must cease.
However, it is crucial to note that this is not a high-performance "power" cell specifically designed for high current usage. Instead, it is a high-capacity "energy" cell for low to moderate power levels and extended runtime. The voltage sag and power loss in the cell at higher current levels become significant. It is advised not to exceed 20A.
