How to use:
These new Silicon anode based batteries can be charged just like a LiPo or LiIon, to 4.2V/cell. We recommend landing at 2.75V per cell, or 33V for this pack.
 
Integration Notes:
Charge and discharge power and current rating is limited by the amount of airflow over the battery during use. Cell skin temperature must remain below 70C during use
