Custom LiFePO4 Battery Packs for Energy Storage & Backup Power
THOR Power designs and manufactures custom LiFePO4 (LFP) battery packs for energy storage, UPS, backup power and portable power systems, with configurable voltage, capacity, BMS, housing and interfaces.

SYSTEM FIT & APPLICATIONS
LiFePO4 Battery Packs Engineered Around Your Power System
A reliable battery pack must be designed around system voltage, load current, required runtime, charging method, BMS protection, installation space and external interfaces—not selected by capacity alone.
Engineered for Stable Backup Power and Long-Term Use
LFP chemistry offers strong thermal stability and long cycle-life potential, but reliable operation still depends on correct electrical, protection and mechanical integration.
Before sampling, THOR Power reviews the load profile, series-parallel configuration, current limits, enclosure and interfaces against the actual operating conditions.

Full-Process Quality Control for LiFePO4 Cells & Battery Packs
As a source manufacturer with cell-production and battery-pack capabilities, THOR Power controls critical stages from slurry preparation, electrode coating, calendering and slitting through cell assembly, electrolyte filling, formation, aging and capacity grading, then continues verification through pack assembly, BMS testing and final shipment release.

Quality Control Starts with Cell Manufacturing
Battery pack consistency is determined upstream by electrode uniformity, moisture control, electrolyte filling, formation and cell grading—not only by final assembly. THOR Power combines cell-process control with pack-level inspection and electrical testing to maintain traceability from cell production through shipment.
Electrode Preparation & Coating Control
Slurry mixing, viscosity, solid content, coating weight, coating uniformity and electrode surface condition are monitored before calendering.
Calendering, Slitting & Electrode Inspection
Electrode thickness, compaction density, width, edge quality and burr condition are checked before the electrodes enter cell assembly.
Cell Assembly & Electrolyte Filling
Electrode alignment, tab connection, insulation, electrolyte volume, moisture control and sealing are checked according to the cell manufacturing specification.
Formation, Aging & Capacity Grading
Formation curves, aging results, capacity, voltage and internal resistance are reviewed before cells are graded and grouped for pack production.
Pack Assembly, BMS & Electrical Testing
Cell matching, busbar welding, insulation, BMS thresholds, charge-discharge behavior, output voltage, capacity and current performance are verified.
Final Inspection, Traceability & Shipment Release
Appearance, dimensions, connector polarity, labeling, packing, inspection records and shipment details are checked for traceability before release.

LiFePO4 Battery Pack FAQ for Energy Storage & Backup Power
Practical answers about LiFePO4 battery voltage, capacity sizing, BMS protection, 51.2V home energy storage, portable power, sample validation and project requirements.
How do I choose the right LiFePO4 battery pack voltage for my system?
Match the battery's nominal and operating-voltage range to the inverter, controller, DC bus and charger—not to capacity alone. Common LiFePO4 platforms include 12.8V (4S), 25.6V (8S), 38.4V (12S) and 51.2V (16S). The selected charger must also match the series count and final charge voltage. THOR Power confirms continuous load, peak current, charging method and equipment voltage limits before defining the pack configuration.
Why is a 51.2V 100Ah LiFePO4 battery commonly used for home energy storage?
A 51.2V LiFePO4 battery normally uses 16 cells in series: 16 × 3.2V = 51.2V. At 100Ah, its nominal energy is 51.2V × 100Ah = 5120Wh, or 5.12kWh. This platform suits many 48V-class home energy storage inverters, but compatibility still depends on the inverter voltage window, BMS current rating and CAN/RS485 protocol. Actual usable energy is lower after discharge limits and conversion losses are considered.
How do I calculate the LiFePO4 battery capacity required for backup power?
Start with load power, required runtime, system efficiency and usable depth of discharge:
Required energy (Wh) = Load (W) × Runtime (h) ÷ Efficiency ÷ Usable DoDFor example, a 500W load for 4 hours, assuming 90% efficiency and 90% usable DoD, requires about 2469Wh. At 51.2V, this is about 48.2Ah before allowances for peak load, inverter standby use, temperature and aging. Final sizing should be checked against both continuous and surge power.
What protection and communication functions should a LiFePO4 BMS include?
The BMS should provide overcharge, over-discharge, overcurrent, short-circuit and temperature protection, together with cell balancing and appropriate continuous and peak current ratings. Energy storage projects may also require contactor control, pre-charge logic and multiple temperature sensors. For inverter-connected systems, CAN or RS485 communication must use a protocol compatible with the target inverter; having the same connector does not guarantee communication compatibility.
Why do LiFePO4 battery packs with the same voltage and capacity perform differently?
Nameplate voltage and Ah do not describe the complete battery. Performance also depends on cell grade, capacity tolerance, internal resistance, cell matching, busbar and weld quality, BMS current limits, wiring resistance, temperature sensing and enclosure thermal design. These factors change voltage sag, heat generation, usable capacity and cycle life under load. Battery packs should therefore be compared at the required current, temperature and duty cycle—not by voltage and capacity alone.
Can a LiFePO4 portable power station be customized with AC, DC and USB outputs?
Yes. A portable power station is a complete power system rather than only a battery pack. Its battery, BMS, inverter, AC socket type, continuous and surge power, DC outputs, USB-A/USB-C PD ports, MPPT input, charger, display and thermal design must be engineered together. THOR Power can review housing, port layout, display UI, branding and packaging, while AC voltage, frequency and socket configuration are selected for the target market.
What should be tested before mass production of a LiFePO4 battery pack?
Sample validation should confirm cell capacity and internal resistance, pack voltage and capacity, BMS protection thresholds, continuous and peak discharge, charging behavior, temperature rise, thermal protection, connector polarity and enclosure fit. Projects with communication should also verify CAN/RS485 operation and inverter compatibility. Final testing should reproduce the actual load, runtime, charger, ambient temperature and installation conditions before the design is released for batch production.
What information should I provide for an accurate LiFePO4 battery quotation?
Send the required nominal voltage, continuous and peak load current, target runtime or energy, charging method, installation space, operating temperature and application. Also specify BMS functions, CAN/RS485 protocol, connector or output interfaces, enclosure, mounting, quantity, target market and certification needs. Existing drawings, inverter models, charger specifications, old battery samples or system test data help THOR Power review compatibility and prepare a more accurate proposal.
