STOK Electric Marine LiFePO4 Batteries
Modular marine LiFePO4 battery packs, 12-800 V, 105-340 Ah modules, with integrated BMS and CAN-Bus communication; DNV, Lloyd's Register and ES-TRIN approved versions.
Description
STOK Electric marine batteries are compact, modular LiFePO4 battery packs for electric and hybrid boat propulsion. They are water-resistant and lightweight, and can be placed flexibly around the vessel or connected in series up to 800 V.
Key features
- LiFePO4 chemistry with prismatic cells for thermal stability, long cycle life and safety
- Integrated Battery Management System monitoring each cell
- CAN-Bus communication, e.g. to signal generators when charge is low
- Modular layout for retrofits and new builds
- Passive or air cooling; no water cooling required
- Optional heated versions for freezing conditions
- Third-party batteries can be integrated if they meet safety and performance standards
