Nimh

Introduction

Robotino v3 can be equipped with 3 accumulator packs each of which contains 18 NiMH battery cells. Each cell has a capacity of 9Ah and every accumulator pack has 9Ah/21.6V which is about 200 Wh. So with 3 NiMH accumulator packs Robotinos batteries have 600Wh. The average power consumption of Robotino is at about 1.5A at 21V so about 30W. That leads to 20h of operation without the need of charging the batteries.
