Solar cell specially developed for the bike. Attach it to the bike or to the roof of the shed (garage door is also possible). For convenience, make a connector on the battery. Park the bike, connect the plug and the sun will do the rest of the work. It will keep track of the battery without the need for power. The battery remains optimal and will never run out. This is highly recommended! In other areas, for example in sailing, they already make frequent use of this.

Working method:
the device tests the invading solar energy
from 1 volt onwards, the smart system 'decides' on an impulse or duration charge and automatically ensures the fastest charging.
Maintenance mode: continues on the next day if the battery has stopped charging at night otherwise the program will return to OPTIMALISING mode.
charging indication every 3 seconds
ready-to-use indicator for STD and high performance AGM batteries
consumes less than 0.5 mA in monitoring mode
automatically switches to "Charging" mode when the sun's intensity is sufficient
Mounting:

The OptiMate charge controller can be placed close to the vehicle or battery for easy tracking of charging and maintenance progress.
The Solar Panel must be mounted and positioned in such a way that direct sunlight can penetrate it.
