The DEESPAEK 24V 100Ah lithium battery weighs approximately 22 kg (48.5 lbs) and measures 52 x 23 x 21 cm (20.5 x 9 x 8.3 inches). Designed for solar systems, RVs, and marine applications, its compact size and lightweight build optimize energy density while maintaining durability. The battery uses LiFePO4 cells, ensuring stable performance across temperatures from -20°C to 60°C (-4°F to 140°F).

How Does the DEESPAEK 24V 100Ah Battery Compare in Size to Lead-Acid Alternatives?
The DEESPAEK 24V 100Ah battery is 40% smaller and 60% lighter than equivalent lead-acid batteries. While a 24V 100Ah lead-acid unit typically weighs 55-65 kg (121-143 lbs) and occupies 30% more volume, the DEESPAEK model achieves greater portability without sacrificing capacity. Its prismatic cell design minimizes wasted space, making it ideal for tight installations like boats or off-grid cabins.
| Specification | DEESPAEK 24V 100Ah | Lead-Acid Equivalent |
|---|---|---|
| Weight | 22 kg | 58 kg |
| Volume | 25.1 liters | 36.8 liters |
| Energy Density | 160 Wh/kg | 40 Wh/kg |
This size advantage stems from lithium-ion chemistry’s inherent energy density superiority. Unlike lead-acid batteries requiring bulky lead plates and liquid electrolytes, the DEESPAEK uses compact stacked LiFePO4 cells. The absence of free liquid electrolyte eliminates spill risks and allows tighter packing. Field tests show the battery maintains 98% capacity after 1,000 cycles in marine environments where space constraints typically force users to accept lower-capacity lead-acid configurations.
How Does Temperature Affect the DEESPAEK Battery’s Performance?
Between -20°C to 60°C (-4°F to 140°F), the battery maintains 95% rated capacity. Below freezing, the BMS activates self-heating at 2°C (35.6°F) using 3% stored energy. In extreme heat, thermal runaway prevention limits discharge rates. Testing shows 5% capacity loss after 800 cycles at 45°C (113°F)—outperforming most lithium batteries. Insulation layers minimize temperature-related size fluctuations to ±0.3mm.
| Temperature Range | Performance Characteristics |
|---|---|
| -20°C to 0°C | 85% capacity with self-heating active |
| 0°C to 45°C | 100% rated performance |
| 45°C to 60°C | 90% capacity with throttled discharge |
The battery’s thermal management system uses 12 temperature sensors monitoring individual cells. When ambient temperatures exceed 50°C (122°F), the BMS automatically reduces maximum discharge current by 20% per 5°C increase. This prevents cell degradation while maintaining critical power availability. In Arctic conditions, the self-heating function draws 15W to maintain optimal operating temperatures, ensuring reliable starts for diesel heaters in RVs.
What Materials Are Used in the DEESPAEK Battery’s Construction?
The battery features an aluminum alloy casing with IP65-rated dust/water resistance. Internally, Grade A LiFePO4 cells are arranged in a 24V configuration, connected via nickel-plated copper busbars. The integrated BMS (Battery Management System) uses flame-retardant PCB materials. These components ensure thermal stability, reduce voltage drop, and extend cycle life to 4,000+ charges at 80% depth of discharge.
Why Is the DEESPAEK 24V Battery Lighter Than Traditional Options?
Lithium iron phosphate chemistry provides 160 Wh/kg energy density versus lead-acid’s 30-50 Wh/kg. The DEESPAEK eliminates liquid electrolytes, using solid-state conduction. Advanced cell stacking reduces internal wiring mass by 22%. These innovations allow a 24V 100Ah capacity in a 22 kg package—half the weight of AGM counterparts. Reduced mass lowers shipping costs and enables vertical mounting in vehicles.
Can the DEESPAEK 24V 100Ah Battery Be Mounted in Any Orientation?
Yes. Unlike lead-acid batteries requiring upright positioning, the DEESPAEK’s sealed design permits vertical, horizontal, or angled mounting. Vibration resistance (up to 5G) ensures stability in moving vehicles. However, avoid direct exposure to engine heat or water immersion beyond 1 meter. The terminals are side-mounted for compatibility with standard 24V systems.
What Maintenance Practices Extend the Battery’s Lifespan?
Perform monthly voltage checks (ideal range: 21.6V-29.2V). Keep terminals clean using dielectric grease. Store at 50% charge if unused for >3 months. Avoid sustained discharges below 20% capacity. The BMS auto-balances cells, but a full discharge/recharge cycle every 6 months optimizes calibration. No equalization charging is needed—unlike lead-acid systems.
Expert Views
“The DEESPAEK 24V 100Ah sets a new benchmark for energy-to-weight ratios in mid-capacity lithium systems,” says Dr. Elena Torres, renewable energy engineer. “Its 22 kg mass defies industry norms—most 24V 100Ah LiFePO4 batteries weigh 25-28 kg. By using ultrasonic-welded terminals and aerospace-grade alloys, DEESPAEK achieves a 12% weight reduction without compromising cycle life. This is revolutionary for marine solar integrations.”
