Testing the CBM performace
Testing the CBM performace
We tested the CBM boards before releasing them to our customers. You can see the voltage level of the 3 cells (on the left side)kept bellow 3.6V, while the right cell is not ballanced and the voltage increases above 3.9V.

FAQ: LiFePO4 - LiFeYPO4 cell cycle voltage levels
The LFP (LiFePO4 or LiFeYPO4) cells operate within the 2.5 V to 4.0V voltage levels. In order to extend the life-span, many users prefer to operate within narrower voltage levels - as seen from the table above.

The deep cycles for the LiFePO4 cells used in these PCM batteries is as low as 2.00V. This means the minimal cut-off voltage is approx 8.00V.
Note that the PCM inside this type of battery is designed only for last moment safety power-disconnect. In normal operation, the user mus
