Battery Installation
4.3.2 Multiple Batteries
Connect batteries in series and parallel via power adapter cables to increases voltage
and capacity.
!
Caution
• Check if the voltage difference between the batteries is less than 0.1 VDC before using them in
series connection, or 0.5 VDC in parallel connection. If not, please balance the voltage first.
Otherwise, over-current protection may be triggered due to the large voltage difference.
• Do not mix batteries of different brands, types, models or life spans.
• In order to prolong the life span of the batteries, please make sure the length, diameter and
internal resistance of the power cables are the same when using multiple batteries.
Note
• Please refer to Section 5.3.1 for terminal connection and external devices connection.
• When batteries are used in series and parallel connection, it is recommended to use with a
busbar to distribute power effectively.
• The power cable connection methods provided in the manual are for reference only. The actual
optimal connection method varies depending on the cable size, equipment devices connected
and environmental conditions.
