Operating manual Cruise 2.0
We recommend that you achieve the required battery capacity in Wh using as few parallel
connections as possible with as few batteries as possible. So, to give yourself a battery
capacity of e.g. 4,800 Wh (at 24 V) it is better to use two 12 V / 200 Ah batteries rather than
several parallel and serially linked batteries (e.g. four 12 V / 100 Ah batteries) Firstly, this
avoids safety risks from battery configurations. And secondly, capacity differences
between the batteries that already exist at the time of the configuration or that develop
later have a negative effect on the overall battery system (capacity loss, also called
drifting). Thirdly, this way you reduce losses at the contact points that can amount to 2-%
of the battery capacity.
To avoid safety risks, capacity losses and contact point losses with serial and parallel
battery configurations, always only combine the same type of batteries (same capacity,
same age, same manufacturer, same charge condition).
• Serial and parallel configured batteries must always have the same
charge condition. That is why you must use only the same type of
batteries in configurations (same capacity, same age, same
manufacturer, same charge condition) and fully charge each battery
separately in your charger before you connect it up. Differences in the
charge condition can lead to extremely high compensatory currents or
overloads that overload the cables and connectors or the battery itself.
In extreme cases, this can cause fires and injuries.
