Make your own Li-Ion battery pack

Hi guys,

Did you know you could build your own Li-Ion battery pack ?

Li-Ion batteries have the highest energy density per unit of mass available to us.

In comparison with LiPo batteries, you get 30% less weight for the same mAh capacity, which translates into direct endurance or increased flight autonomy.

Ready made…
