What Are the Key Specifications of the LiFePO4 24V 120Ah Battery?
This battery uses 32700 LiFePO4 cells, providing 120Ah capacity and 3072Wh energy. The built-in 120A BMS ensures overcharge/discharge protection, cell balancing, and short-circuit prevention. Operating between -20°C to 60°C, it weighs 24kg—40% lighter than lead-acid equivalents—and supports 4000+ cycles at 80% depth of discharge.
The modular architecture allows capacity expansion through parallel connections, enabling users to scale from 120Ah to 360Ah configurations without voltage drops. Each cell group features independent temperature sensors that adjust charging rates in 0.1°C increments. The aluminum alloy casing provides EMI shielding up to 60dB, crucial for integration with sensitive navigation equipment in marine applications.

How Does the 48V LiFePO4 Variant Enhance High-Power Applications?
The 48V configuration enables 5kW+ continuous discharge, ideal for industrial equipment, marine thrusters, and off-grid solar arrays. Stackable up to 4 units (48V/480Ah), it achieves 98% round-trip efficiency, reducing energy waste by 15% compared to NMC batteries. Its modular design allows parallel/series connections for 96V or 200Ah+ systems.
Deespaek 36V 100Ah LiFePO4 Battery Guide
When used in electric ferry propulsion systems, the 48V bank delivers 3000A peak current for 10 seconds without voltage sag. The integrated CAN bus 2.0B interface enables real-time communication with hybrid inverters, transmitting 14 data points including state-of-health metrics and thermal profiles. This allows predictive maintenance scheduling, reducing downtime by 22% in commercial solar installations according to field tests.
Why Choose LiFePO4 Over Traditional Lithium-Ion Batteries?
LiFePO4 eliminates thermal runaway risks—critical for confined spaces—with a stable cathode that withstands 500°C vs. NMC’s 200°C limit. It maintains 80% capacity after 10 years versus lithium-ion’s 50% degradation. The phosphate chemistry enables faster charging (0-100% in 2 hours) without voltage sag, supported by 0.5C constant current absorption.
What Safety Features Are Integrated Into the BMS?
The 120A BMS includes MOSFET-based current limiting (2000A interrupt capacity), real-time cell voltage monitoring (±0.5mV accuracy), and temperature-compensated charging. It activates cell balancing when voltage variance exceeds 20mV and provides Bluetooth-enabled SOC monitoring with ±1% precision through dedicated apps.
How Does the 32700 Cell Design Improve Performance?
The 32700 cylindrical cells (32mm diameter x 70mm height) offer 15% better heat dissipation than prismatic designs. Using graphene-enhanced electrodes, they achieve 150Wh/kg energy density. The nickel-plated steel casing resists corrosion at 85% humidity levels, while the laser-welded terminals withstand 50G vibration forces.
During cyclic load testing, 32700 cells maintained 95% capacity after 2000 cycles at 1C discharge rates. The spiral-wound electrode configuration reduces internal resistance to 0.8mΩ per cell, enabling 98% energy efficiency during 2C bursts. This design proves particularly effective in cold climates, retaining 85% of rated capacity at -20°C without auxiliary heating.
Can These Batteries Operate in Extreme Environments?
Tested at -40°C (with heater assist) and +75°C ambient temperatures, the battery maintains 80% capacity. The IP67-rated enclosure protects against dust ingress and temporary submersion (1m/30min). High-altitude performance (up to 5000m) is ensured through pressure-equalized venting membranes.
What Are the Cost Savings Over 10 Years?
With 4000 cycles at $1500 initial cost, the per-cycle expense is $0.375—compared to lead-acid’s $1.20/cycle (1200 cycles at $900). Solar users save $6000+ in generator fuel over a decade. Reduced maintenance (no watering/equalization) cuts labor costs by 80% versus industrial lead-acid banks.
| Battery Type | Cycles | Initial Cost | Per-Cycle Cost | 10-Year Fuel Savings | Maintenance Cost Reduction |
|---|---|---|---|---|---|
| LiFePO4 24V | 4000 | $1500 | $0.375 | $6000+ | 80% |
| Lead-Acid | 1200 | $900 | $1.20 | $0 | 0% |
