The DEESPAEK 24V 100Ah LiFePO4 Battery delivers exceptional energy density, 4,000+ deep cycles, and a built-in BMS for safety. Its lightweight design (22 kg), wide temperature tolerance (-20°C to 60°C), and 10-year lifespan make it ideal for solar storage, RVs, and marine applications. This lithium iron phosphate battery outperforms traditional lead-acid alternatives in efficiency and durability.

How Does the Battery’s Cycle Life Enhance Longevity?
With 4,000-6,000 deep discharge cycles at 80% DoD (Depth of Discharge), the DEESPAEK battery lasts 8-10 years under daily use. This exceeds standard lithium-ion batteries (2,000 cycles) and lead-acid models (300-500 cycles). The LiFePO4 chemistry prevents capacity fade, maintaining ≥80% capacity after 3,000 cycles, even with frequent partial recharging.
The secret lies in the stable crystalline structure of lithium iron phosphate cathodes. Unlike cobalt-based batteries, LiFePO4 cells experience minimal electrode degradation during charge/discharge cycles. This structural integrity allows the battery to maintain 95% capacity retention through the first 1,000 cycles, compared to 80% retention in typical NMC batteries. Users can expect:
| Cycle Count | Capacity Retention | Equivalent Years |
|---|---|---|
| 1,000 | 95% | 2-3 years |
| 3,000 | 85% | 6-8 years |
| 5,000 | 80% | 10+ years |
What Safety Mechanisms Protect Against Overheating?
The integrated Battery Management System (BMS) monitors voltage, current, and temperature in real-time. It prevents overcharge (＞28.8V cutoff), over-discharge (＜20V cutoff), and short circuits. Ceramic-coated separators and flame-retardant electrolytes ensure thermal stability up to 300°C, eliminating explosion risks common in NMC batteries. Passive balancing extends cell lifespan by maintaining ±0.02V cell voltage variance.
Advanced thermal runaway prevention combines three layers of protection. The aluminum alloy casing acts as a heat sink, dissipating 40% more thermal energy than plastic enclosures. Within the cells, a shutdown separator melts at 130°C to block ionic flow during overheating. The BMS implements graduated responses to temperature spikes:
| Temperature | BMS Action | Recovery Method |
|---|---|---|
| ＞65°C | Reduce charge current by 50% | Automatic reset at 55°C |
| ＞75°C | Disconnect load | Manual power cycle |
| ＞85°C | Permanent circuit break | Factory service required |
Which Applications Benefit Most From This Battery?
Solar energy storage systems (compatible with 3,000W inverters), off-grid cabins, and electric vehicles (golf carts, scooters) leverage its high discharge rate (100A continuous, 200A surge). Marine uses thrive on its IP65 waterproof rating and vibration resistance (MIL-STD-810G certified). Telecom backup systems utilize the -20°C operational capability, critical for cold climates.
How Does Weight Compare to Traditional Batteries?
At 22 kg, the DEESPAEK 24V 100Ah weighs 60% less than equivalent lead-acid batteries (55-60 kg). This reduces shipping costs (2.6x lower freight class) and enables easier installation in rooftop solar setups. The compact 522×240×218mm dimensions fit standard battery trays designed for 24V systems.
What Maintenance Practices Optimize Performance?
No watering or equalization charges needed. Store at 50% SOC (State of Charge) during long inactivity. Use a compatible LiFePO4 charger (29.2V absorption voltage). Clean terminals quarterly with dielectric grease to prevent corrosion. Capacity recalibration (full discharge/charge cycle) every 6 months maintains accurate SOC readings.
Can Multiple Units Be Connected in Series/Parallel?
Up to 4 batteries can connect in series (max 48V) or parallel (400Ah capacity). Use copper busbars with 35 N·m torque settings to minimize resistance. Paralleled systems require ≤0.1V pre-connection voltage difference. Avoid mixed configurations with older batteries – ≥20% capacity variance triggers BMS shutdowns.
“The DEESPAEK’s use of automotive-grade A-grade cells ensures ≤3% self-discharge/month versus 10-15% in lead-acid. Its 92% round-trip efficiency (AC-coupled systems) outperforms Tesla Powerwall’s 90%. For off-grid setups, this translates to 18% fewer solar panels needed compared to AGM batteries.”

FAQs
- Does It Work With Existing Lead-Acid Chargers?
- No – Use only LiFePO4-specific chargers. Lead-acid chargers’ higher float voltages (13.8V vs 13.6V) cause premature BMS cutoffs. Recommended: 24V 30A minimum charger with temperature compensation (±3mV/°C).
- What Warranty Protections Are Provided?
- 5-year full replacement, prorated to 7 years. Covers capacity below 80% within 3,000 cycles. Exclusions: physical damage, under-voltage lockouts from improper storage. 24/7 technical support includes remote BMS diagnostics via Bluetooth dongle.
- How to Monitor Battery Health?
- The optional DEESPAEK SmartShunt ($89) tracks SOC ±1% accuracy via Bluetooth. Integrates with Victron VenusOS and SolarAssistant. BMS fault codes (21 error types) display through LED indicators: 3 green (75-100%), 2 yellow (50-75%), 1 red (＜25%).
