A 73.6V 108Ah LiFePO4 pack for marine propulsion, outboards, trolling motors, tenders and electric surfcraft. Nominal energy is approximately 7.95 kWh (calculated from nominal voltage and rated capacity; delivered usable energy depends on discharge current, operating temperature, cutoff voltage, and application duty cycle). The pack delivers 300A continuous discharge current, with peak discharge capability up to peak: 350A (2s pulse duration, subject to thermal and BMS limits), rated at a full 2.78C draw, with headroom for the surge loads motive duty demands.
Charging at 15A brings it to full in roughly 8 hours. The operating window is -20~75°C on discharge and 0~45°C on charge. The pack measures 683x423x230mm (top cover size) and weighs 76 kg.
Within our 72V range this sits between the 100Ah and 205Ah builds. If your runtime target is tighter than expected once we model the duty cycle, the 205Ah configuration is the usual next step; if weight or envelope is the binding constraint, the 100Ah build is lighter.
We design to the installation: sealing level, terminals, cable runs and mounting. Communication over CAN or RS485 lets the pack talk to the motor controller and helm display, and Bluetooth covers checks on board; 4G for remote monitoring of moored vessels is a custom option.
Is the pack sealed for marine environments?
Ingress protection is specified per project. Tell us the mounting location and exposure and we recommend a rating and enclosure.
Can packs be paralleled for larger vessels?
Yes, with matched packs and a BMS configured for it. Tell us the target bank size at quotation stage.
Grade A prismatic LFP cells, generally specified with UL recognition at cell level. Every pack ships with a UN38.3 test summary and MSDS prepared for air, sea and road transport. Assembly and testing take around 7 working days. Cell supply is what sets the overall schedule: when the cells your design needs are in stock, samples ship in 10–15 working days; when they have to be sourced, allow 20–25. Tell us your target date early and we will confirm cell availability before you commit to it. Production runs 20–25 working days. There is no minimum order quantity — this is a custom design business and we quote single units, with pricing improving noticeably from 100 packs upward. LiFePO4 warranty typically runs 3–5 years, set against the discharge duty of the application; high-rate cycling shortens it.
Our engineering division designs bespoke battery packs with CANBUS, RS485, custom aluminum enclosures, and matched chargers.
