Test conditions:
- Navi komplet teaching hazards
- Bateriebox connected
The battery box must both the Navi supply in these circumstances as well as the internal load Naviakku.
I let the navi then run until the battery box was empty and turned off the protection circuit.
The runtime with this and also with the Black batteries this manufacturer was 10 hours and 15 or 20 minutes !!!
I still have a Pack 2600 mAh 18650 rechargeable batteries from a different manufacturer, mind you 2600 mAh !!!!
Same test setup identical conditions (Navi previously made teaching) with these batteries lieft the navi 23 hours without interruption until the battery box switched off !!
The 2600 mAh these alleged 4000 mAh ie by more than !!!!! Overhauled 13 hours !!!!! So stay away from the 4000 mAh battery of this manufacturer, the data on capacity have been at least doubled if not tripled, and not in accordance with the real capacity.
