How long does the trailer battery last compared to the standard Robop?

With regard to battery charging, Robop needs to be charged approximately every two weeks.. This depends on the number of hours of daylight and on the prevailing weather conditions, particularly wind speed. In a high wind the servos controlling movement have to work harder and hence they consume more power. We recommend charging every week for safety The trailer version is supplied with a large lead-acid leisure battery and therefore can be left for 4-6 months between charges, again the time will depend on daylight hours and weather conditions.
