Installation diagram for a battery pack based on the 12V monolithic LP batteries
This diagram give details on how to install the battery pack using the 12V monolithic LP batteries. This solution is especially suitable for small systems like EV boats operating at 24V (2 batteries), 48V (4 batteries) or EV cars (with 6 and more batteries).  Download  the PDF file with the installation.
The management of the battery pack is done by means of the AKUMON AKM-A1.  The low discharge warning can be optionally given by the BM1 - battery monitor connected to each 12V battery.  The voltage of each battery is provided by means of the APM1 - Battery Indicator.
If you have any suggestions or questions to this installation, please let us know.

Using the LFP cells and LP batteries in the sea/lake ships and boats
Many boats’ owners have installed the LiFePO4 cells (or 12V LP batteries) into their boats.  There are several possible applications for the lithium iron cells:
1) Boats with electric enginesThe LFP cells/LP batteries are used to replace conventional lead-acid (SLA) batteries. Advantages: the lithium solution is lighter, provides higher capacity and discharge currents. The LFP cells/LP batteries allow for faster charging and keep the performance even at low temperatures (Nordic Sea).
2) Boats with electric equipments on boardThe LFP cells/LP batteries provide the power for the on-board equipment during on-sea trips. They are used to replace the lead acid battery bank. The LFP cells/LP batteries are lighter, give higher capacity and last longer.
3) Boats with solar charging (solar panels)The LFP cells/LP batteries replace the “solar charge lead-acid batteries”.  They work fine with many solar charge controllers.  Unlike lead-acid (SLA) batteries, the LFP/LP solution allows for faster charging (more solar panels can be used). The battery bank can have  significantly higher capacity while keeping the original weight.
Conclusion: The LFP cells/LP batteries are a universal solution to replace the lead-acid (SLA) batteries. With the LFP cells/LP batteries you will ge a longer time on the sea!

Connecting 12V batteries to make a high capacity battery block
The drawing with idea how to connect the 12V batteries into high voltage (48V), large capacity battery block. Each battery is protected by a fuse to prevent from the damage of the whole string. The BMS manages each parallel block of the 12V batteries.
