For those who want a higher Amp Limit and don't mind shorter battery life, choose the Golisi or Molicel batteries. In Short: Most people will be fine with the Samsung 25R batteries. Generally trust the latter more than the former sometimes Amp Limits are overstated by the manufacturer, including stating Pulse rather than Continuous ratings. Use Steam Engine's calculator to detect your required Amp Limit.Īmp Limit shown is shown as Manufacturer's Rating ( Mooch's Tested Rating) unless both figures are the same. For most regulated devices, the Amp Limit will not be a concern as there are built-in safety mechanisms. The Amp Limit required is dependant upon the device and tank/coil system you are using, as well as the power (wattage) you are using it at. For devices running batteries in parallel, the Amp Limit is multiplied by the number of batteries being used (ie. This means that holding the battery down for longer than approximately one second will be safe at or under this limit. The higher this number, the longer your battery will generally last, although usually higher capacity battery have a lower Amp Limit.Īmp Limit measures the number of amps that the battery can support your device outputting at a continuous rate. Price is for one single Sony VTC6 18650 battery.ĭIFFERENCES BETWEEN 18650 BATTERIES SOLD BY THE VAPE STORE BatteryĬapacity (mah) measures the milliamp hours of the battery, or the battery life. The Sony VTC6 battery is an 18650 with a 3000mah capacity and a maximum continuous discharge rating of 19A (officially 15A, but rated 19A by Mooch). We highly recommend reading our Li-Ion precautions sheet on handling Li-Ion.NOTE: Sony VTC6 batteries are now difficult to obtain and may not be restocked. It is extremely important to use caution when working with and using lithium ion batteries as they are very sensitive to charging characteristics and may explode, burn, or can cause a fire if misused or mishandled. A BMS can or may monitor such things as the batteries charge state, balance the battery, report data, temperature, voltage, state of health. The PCM will help protect the user from potential fire and explosion.Ī battery management system (BMS) is a similar circuit, with far more features. The PCM will help to protect the cells or battery pack from over charging, over discharge and over current and short protection. Generally Li-Ion cells in most consumer devices will have a protection circuit module (PCM or PCB). Some of the advantages of Li-Ion include a high energy density, low maintenance, low self discharge rates and depending on the cell a high maximum continuous discharge rate. However, they are increasingly finding there way into more and more diverse consumer devices such as high powered LED torches to door bells. These cells have a nominal open circuit voltage of 3.7V per cell and a full charge voltage of 4.2V.ġ8650 cells have been used for some time in laptops, power tool batteries and numerous other battery pack applications. The first two digits are the approximate diameter, in this case 18mm and the following 3 digits are the approximate height in tenths of millimeters, in this case 65mm. At it’s most basic an 18650 is a Li-Ion cylindrical cell that uses its dimensions as it’s designation.
