Lithium batteries
Lithium battery solutions for energy, traction and cold climate
DPT works with LiFePO4 cells, ready-made packs and custom battery configurations for customers replacing lead-acid batteries or building new power systems.
Applications
Where batteries are used
Telecom backupForklifts and AGVMarine powerRV and off-gridHeavy machinery startingEnergy storage
Telecom and 5G
Backup for base stations in heat and cold, with more autonomy in the same volume.
Warehouses and 3PL
Forklifts and AGV fleets where opportunity charging can reduce battery swaps.
Special machinery
Cold-start and reserve packs for construction, mining and field equipment.
Drones and tools
High-rate cells and packs where weight, current and form factor matter.
Marine
Lithium packs for electric propulsion, auxiliary power and seasonal service reduction.
RV and off-grid
Autonomous power systems with lower weight and better winter usability.
What to send for selection
Voltage, capacity, peak and continuous current, temperature range, dimensions, communication interface, quantity and target delivery region.
1. Requirements
Voltage, capacity, current profile, temperature range, size and quantity.
2. Configuration
Cells, BMS, enclosure, communication and charging approach are selected.
3. Sample check
The pack is validated against load, charging, temperature and installation needs.
4. Supply
Production, quality control and lithium-battery logistics are coordinated.
