The 48V 100Ah LiFePO4 battery with BMS is a high-efficiency energy storage solution designed for tricycles, golf carts, solar systems, and scooters. Its lithium iron phosphate chemistry ensures 4,000+ cycles, thermal stability, and rapid charging via the included 10A charger. The integrated BMS protects against overcharge/over-discharge, making it 50% lighter and 30% more space-efficient than lead-acid alternatives.

How Does LiFePO4 Chemistry Enhance Battery Performance?
LiFePO4 batteries utilize lithium iron phosphate cathodes that prevent thermal runaway while delivering 3.2V per cell. This chemistry enables stable voltage output between 20%-100% charge levels, unlike volatile NMC batteries. The crystalline structure resists degradation, maintaining 80% capacity after 3,000 cycles even in 45°C environments – critical for solar storage and electric vehicle applications.
The unique olivine structure of LiFePO4 cells provides inherent safety advantages. Unlike cobalt-based batteries, these units maintain structural integrity during overcharge scenarios, with exothermic reactions beginning at 270°C versus 150°C in NMC cells. This allows for tighter cell packing in battery banks, achieving energy densities up to 130Wh/kg. For solar installations, the flat discharge curve (48V±0.5V from 20-95% SOC) maximizes inverter efficiency, particularly crucial when paired with MPPT controllers.

What Are the Key Applications of 48V Golf Cart Batteries?
Beyond golf carts, these batteries power 1.5kW-3kW tricycle motors for 60-80km ranges per charge. In solar setups, four units can store 19.2kWh – enough to run a 2kW off-grid cabin for 9 hours. Scooter conversions achieve 55-65km/h speeds with 98% charge efficiency versus 75% in lead-acid systems, reducing charge frequency by 40%.
Deespaek Battery BMS Performance
Marine applications benefit from the battery’s vibration resistance, with tested performance under 5G harmonic vibrations. When used in electric ferry systems, two parallel 48V banks can provide 200A continuous current for thrusters. The BMS automatically isolates cells if salinity intrusion occurs, preventing terminal corrosion. For agricultural use, these batteries demonstrate 92% capacity retention after 18 months in dust-intensive environments when properly housed.
| Application | Voltage | Runtime | Cycle Life |
|---|---|---|---|
| Solar Storage | 48V | 9 hours @ 2kW | 4,000+ cycles |
| Golf Cart | 48V | 45 holes | 3,500 cycles |
| Delivery Tricycle | 48V | 120km | 2,800 cycles |
What Safety Certifications Do These Batteries Hold?
Certified to UL 1973, UN38.3, and IEC 62619 standards, these batteries undergo nail penetration tests at 150% SOC without ignition. The flame-retardant ABS casing (V-0 rating) contains thermal events while compression-resistant mounts (500kg force tolerance) prevent structural failure in mobile applications. Optional CANbus communication enables real-time SOC tracking via J1939 protocols.
| Certification | Test Requirement | Performance |
|---|---|---|
| UL 1973 | Overcharge at 2C rate | No explosion |
| UN38.3 | 8m drop test | 0% deformation |
| IEC 62619 | 55°C storage | <0.2% monthly loss |
“The integration of active balancing BMS in 48V LiFePO4 systems represents a paradigm shift. We’re seeing 22% longer service intervals in solar-hybrid golf carts compared to traditional AGM setups. For fleet operators, the 10-year potential lifespan at 80% depth-of-discharge translates to 73% lower TCO over lead-acid alternatives.”
