4.3.2 Parallel Installation
The battery configuration in figure 5 shows a simultaneous parallel and series format. The
parallel configuration allows for capacity to increase while voltage remains the same.
1. Before wiring multiple 12V batteries together, all batteries must be individually charged to
100% SOC using a specified current limit (see specification).
2. Connect batteries together not to exceed 2S3P (2 in series,3 in parallel).
3. The entire group of batteries should then be float charged at a specified current (see
specification) according to the number of series (13.8 V for 1S, 27.6 V for 2S). This float
should be held for at least 24 hours to allow the batteries in the system to fully balance.
4.
We strongly recommend to charge each battery alone before use.
5. To recharge the group, repeat the process starting at step 3. This will ensure that all cells
are once again properly balanced in preparation for the next discharge.
4.3.3 Parallel & Series Installation
As shown in figure 5, a combination of the parallel and series format allows for increased
capacity and voltage resulting in longer run time. For example, if each battery shown below is
a 12V battery, the combined parallel and series installation will result in 24V and twice the
capacity.

Ensure that parallel connections between batteries are completed prior to connecting the
batteries in series.
