Last week the Hantek 365A Data Logger arrived and will be used to log the first charge with the new PIC chip controlling the Zivan NG3 charger. For $75 I thought this logger would be a good addition to my test equipment. It is also available with Bluetooth for a little higher price, and that may be a good feature to have if you are using a tablet to save the log files.


The Hantek 365A can record voltage, current, capacitance, and resistance. The sample rate can be adjusted and the data file can be exported to a log file on a computer, so it can be graphed. I am especially interested in the voltage climb at the end of the charge on the Better Place battery module, as it seems it is still rather flat when you approach 4.2 volts per cell. The PIC chip has been set up to end the charge at 137.5 or 4.3 volts per cell and has been charged to this level in the past, with no apparent heating or gassing of the cells.

When the new PIC chip is tested and the log file from the Hantek logger is graphed, I will post the results.

Thanks for visiting,
