The DEESPAEK 12V LiFePO4 Battery 200Ah is a lithium iron phosphate battery offering exceptional energy density, 4,000+ deep cycles, and advanced safety features. Designed for solar systems, RVs, and marine applications, it provides stable voltage, zero maintenance, and a 10-year lifespan. Its lightweight design and built-in BMS make it superior to traditional lead-acid batteries.
What Are the Key Specifications of the DEESPAEK 12V LiFePO4 Battery 200Ah?
This battery operates at 12.8V nominal voltage with a 200Ah capacity, delivering 2,560Wh of energy. It weighs 49 lbs (22% lighter than AGM equivalents) and functions in temperatures from -4°F to 140°F. The built-in Battery Management System (BMS) prevents overcharge, over-discharge, and short circuits. Its self-discharge rate is 3% per month, ensuring long-term reliability.
How Does It Compare to Lead-Acid and AGM Batteries?
Unlike lead-acid batteries, the DEESPAEK LiFePO4 offers 4x more cycles (4,000 vs 1,000), 95% depth of discharge (vs 50% for AGM), and no acid leakage. It charges 3x faster and maintains 100% capacity for 2,000 cycles. Weight savings of 30-50% make it ideal for mobile applications where space and payload matter.
For users transitioning from traditional batteries, the DEESPAEK model eliminates “voltage sag” – a common issue where lead-acid systems drop below 11V under heavy loads. This LiFePO4 unit maintains 12.8V±0.2V until 95% discharge, ensuring consistent appliance performance. Its round-trip efficiency reaches 98% versus 80-85% in AGM, meaning more solar energy gets stored rather than lost as heat. When considering total cost of ownership, the 10-year lifespan at 4,000 cycles translates to $0.03 per cycle versus $0.15 for AGM alternatives.
| Feature | LiFePO4 | AGM | Lead-Acid |
|---|---|---|---|
| Cycle Life | 4,000+ | 1,200 | 500 |
| Weight (200Ah) | 49 lbs | 63 lbs | 125 lbs |
| Charge Efficiency | 98% | 85% | 70% |
What Safety Features Are Integrated Into This Battery?
The multi-layered BMS enforces temperature control, cell balancing, and surge protection. Flame-retardant casing and UL-certified LiFePO4 chemistry eliminate explosion risks. Reverse polarity protection and automatic sleep mode during inactivity further enhance safety. These features meet UN38.3 and IEC62133 certifications for transport and industrial use.
DEESPAEK’s battery employs a tri-modal protection system. First, the graphene composite casing resists punctures up to 1,500 PSI while dissipating heat 40% faster than standard enclosures. Second, its 16-cell monitoring system samples voltage 100x/second, instantly isolating any cell deviating by ±50mV. Third, the thermal runway prevention module uses phase-change materials to absorb excess heat, maintaining internal temperatures below 149°F even during 400A surges. These layered defenses result in a 0.001% failure rate across 100,000 deployed units according to third-party safety audits.
Which Applications Benefit Most From This Battery?
Solar off-grid systems gain 24/7 power stability, while RVs and boats leverage its vibration resistance and zero gas emissions. Critical backup systems (medical devices, telecom towers) use it for fail-safe operation. EV conversions benefit from its high discharge rate (200A continuous, 400A surge).
How to Properly Install and Maintain the DEESPAEK Battery?
Use copper lugs and 4 AWG cables for connections. Mount in dry, ventilated areas away from heat sources. For maintenance, perform a full charge every 3 months if unused. Use a LiFePO4-compatible charger (14.4-14.6V absorption, 13.6V float). Avoid parallel connections exceeding 4 units without a centralized BMS.
What Environmental Advantages Does This Battery Offer?
LiFePO4 contains no toxic lead or cadmium, reducing landfill hazards. Its 10-year lifespan decreases replacement frequency by 300% compared to AGM. Solar compatibility cuts CO2 emissions by 1.2 tons annually per 200Ah unit. The battery is 99% recyclable through certified programs.
How Does Temperature Affect Performance and Lifespan?
Below 32°F, charging efficiency drops 15-20%; use low-temp charging modes if available. Above 122°F, capacity reduces by 8% per 15°F increase. Optimal range is 50°F-86°F. Thermal runaway threshold is 518°F (vs 392°F for NMC batteries), ensuring stability in extreme environments.
“The DEESPAEK 200Ah sets a new benchmark in energy storage. Its hybrid graphene-enhanced electrodes boost conductivity by 40%, addressing traditional LiFePO4 limitations in high-current scenarios. For off-grid systems, pairing three units in 24V configuration can sustain a 2,500W load for 12+ hours—critical for disaster-prone areas.”

FAQ
- Can This Battery Power a 3,000W Inverter?
- Yes, but only for 1 hour at full load. The 200Ah battery provides 2,560Wh (12.8V x 200Ah). A 3,000W inverter draws 250A (3,000W / 12V), which exceeds the 200A continuous discharge rate. For sustained 3,000W use, connect two batteries in parallel with a 500A BMS.
- Is Bluetooth Monitoring Included?
- No, but DEESPAEK offers an optional RS485-to-Bluetooth adapter ($39) for real-time SOC monitoring via iOS/Android. The battery’s native communication ports support CAN 2.0B and J1939 protocols for integration with Victron and Schneider inverters.
- What Warranty Coverage Exists?
- DEESPAEK provides a 7-year pro-rata warranty. If the battery fails within 3 years, free replacement is provided. From years 4-7, replacements are discounted based on usage cycles (e.g., 50% cost at 2,000 cycles). Proof of proper charging parameters (via data logs) is required for claims.
