Rate Charge Performance
The room-temperature charge curve compares 0.3C, 0.5C, 1C, and 2C charging profiles up to 4.2V. The published 2C continuous charge rating applies at 25±3°C; final charging limits for a complete battery pack must also account for pack thermal design and BMS control.
Rate Discharge Performance
The room-temperature discharge curve compares 0.3C, 0.5C, 1C, 2C, 3C, and 4C test profiles down to the specified cutoff voltage. The PP54N-E continuous discharge rating is 3C. The 4C trace is presented as test data and is not a continuous-discharge rating.
Storage Conditions
For short-term storage of up to one month, store the cell at -20°C to 45°C and relative humidity of 90% or below. For long-term storage of up to one year, store at 0°C to 35°C and relative humidity of 70% or below.

Solution
High-energy cells are often selected for flight time first and current delivery second. That becomes a problem when a platform needs both: a large energy reserve for endurance, stable continuous output under load, and a short high-current pulse during takeoff, climbing, manoeuvring, or payload changes. Oversizing the pack to compensate adds mass and reduces the value of the higher-energy cell.
The PP54N-E is a 54Ah solid-state pouch cell built for that design window. With 304Wh/kg energy density, 3C continuous discharge capability, and up to 10C pulse discharge, it gives integrators a practical starting point for high-energy systems that still need controlled high-rate output. Its -43°C to 65°C operating range also supports projects with demanding ambient-temperature requirements.

Application Areas
- Heavy-Lift UAVs: 54Ah capacity and 304Wh/kg energy density help system designers balance flight endurance against airframe weight, while 10C pulse discharge supports high-demand flight phases.
- High-Altitude and Cold-Climate UAV Platforms: the stated -43°C to 65°C operating range makes the PP54N-E relevant for projects that must evaluate cell performance beyond standard ambient conditions.
- eVTOL and Electric Aviation Development: suitable for engineering evaluations where high specific energy and controlled continuous/pulse power delivery are both design priorities.
- Portable Industrial Power Systems: the large-format pouch design can support custom battery-pack development where runtime, mass, and short-duration peak power must be considered together.
- Custom Battery Pack Programs: LiTrue can help integrators assess series-parallel configuration, thermal design, and application requirements through its custom battery pack development capability.
FAQs
What is the continuous and pulse discharge capability of the PP54N-E?
The PP54N-E is rated for 3C maximum continuous discharge and 10C maximum pulse discharge. C-rate expresses current relative to cell capacity; for a 54Ah cell, 1C equals 54A. Final pack current must also account for thermal design, interconnect resistance, BMS limits, and the actual duty cycle.
Can this cell be used in a 48V-class battery system?
Yes. At 3.60V nominal, a 14S configuration is approximately 50.4V nominal before considering the full operating-voltage window. The final series-parallel design should be confirmed against the equipment voltage range, required usable energy, peak current, and protection requirements.
Is the PP54N-E suitable for low-temperature applications?
It is specified for operation from -43°C to 65°C. Actual available capacity, power capability, charging limits, and heating requirements at the temperature extremes must be confirmed for the intended duty cycle and pack design.
What information is needed to select the right pack configuration?
Provide the target system voltage, required usable energy, continuous and peak current, operating-temperature range, space and weight limits, and expected mission profile. LiTrue's applications team can use this information to evaluate a suitable series-parallel configuration.
Are samples and shipping documents available?
Sample availability, production MOQ, transport documentation, and applicable certifications depend on the project and destination. Contact LiTrue with your required quantity, delivery market, and validation plan so the correct documentation can be confirmed before shipment.
