Charging Cable Adapter for Yuneec H520E/H3 Akku Battery

With this charging adapter 

You can charge the battery of Yuneec H3 / H520E 

The advantage is that the charging process is faster and

 you can use special functions of the charger (if available) such as "storage" (storage voltage) to store the battery in an optimal voltage position when not in use. 

You can also check the battery condition with a "Lipo Checker". It is important (see picture) that the two banana plugs do not come together to prevent a short circuit.
