CellLog 8M Battery Monitor
CellLog is a multifunctional, highly precise voltage meter, weighing only 0.63oz/18g. It tells you not only the voltage of individual cells in the mV range, but also the total voltage of a battery pack, the highest and lowest voltage, and voltage difference between cells. Various alarms can also be setup with this little handy gadget. The 8S version has logging function and can be used as a voltage data recorder for your RC models.The 8M is a simplified version of 8S. It works and looks exactly the same as 8S, except being able to log through a USB port (No USB port on this unit). The pins of both 8M and 8S are both JST-XH compatible. A proper adaptor may be required for ThunderPower, Hyperion, and Kokam type batteries.
