This smart device automatically discharges your Foil Drive battery down to the optimal storage voltage for safe and ideal storage conditions.
All lithium batteries do not like to be left fully charged for prolonged periods, or completely flat (week or longer). A great analogy being that you would try to put kids to bed full of sugar, and you'll also have a hard time getting them to sleep when they're over tired.
If you charge your battery up ready for a session that never eventuates, you can now quickly, safely and automatically discharge your battery back down to storage level.
The device has a smart phone app for monitoring the process and changing settings to speed up the process, lower or raise the cut off voltage etc.
The perfect solution to look after your Foil Drive battery while not using it!
