For extended outdoor adventures, this battery can power a combination of essential devices simultaneously. A typical camping setup might draw 150W continuously (12V fridge + LED lights + phone charger), providing 8 hours of runtime. Medical equipment users appreciate the stable output for CPAP machines, where voltage fluctuations could disrupt therapy. The battery’s pure sine wave inverter compatibility also safeguards sensitive electronics like gaming consoles and DSLR camera batteries.

| RV Water Pump | 60W | 20 hours |
| Security Camera | 8W | 150 hours |
| Electric Blanket | 70W | 17 hours |
How Long Does a 100Ah Lithium Battery Last?
Runtime depends on load: 1,200Wh ÷ device wattage. Example:
- 200W load: 6 hours
- 50W load: 24 hours
With a 90% depth of discharge (DoD), the DEESPAEK battery maintains efficiency over 3,000 cycles, lasting 8-15 years. Temperature (-20°C to 60°C operation) and discharge rates affect longevity.
Real-world longevity depends on three key factors: discharge patterns, charging habits, and environmental conditions. Users discharging to 20% daily can expect 10+ years of service, while those frequently draining to 0% may see 7-8 years. The built-in battery management system (BMS) prevents capacity loss from partial charging – unlike lead-acid batteries requiring full recharges. In solar applications, daily 30% depth of discharge cycles yield 15+ years of operation through 5,000+ potential cycles.
| Discharge Depth | Cycle Life | Equivalent Years* |
|---|---|---|
| 30% DoD | 5,000+ | 15+ |
| 50% DoD | 3,500 | 10 |
| 80% DoD | 2,000 | 6 |
Why Choose LiFePO4 Chemistry for a 100Ah Battery?
LiFePO4 batteries offer thermal stability, non-toxic materials, and zero risk of thermal runaway. The DEESPAEK model includes built-in BMS for overcharge/discharge protection, cell balancing, and temperature control. Its energy density (100-130Wh/kg) surpasses AGM batteries, reducing weight by 50% for portable applications.
Can a 100Ah Lithium Battery Power a Solar System?
Yes. A single DEESPAEK 100Ah battery can store 1.2kWh of solar energy, supporting:
- 300W solar panels (4-5 peak sun hours)
- Off-grid cabins with <1kW daily usage
- Hybrid systems paired with generators
Its 95% round-trip efficiency minimizes energy loss compared to lead-acid’s 70-80%, maximizing solar ROI.
How to Calculate Power Needs for a 100Ah Battery?
- List devices and wattage (e.g., fridge: 120W)
- Estimate daily usage hours (e.g., 5 hours)
- Calculate Wh/day: 120W x 5h = 600Wh
- Multiply by days needed: 600Wh x 2 days = 1,200Wh
- Add 20% buffer: 1,440Wh. A 100Ah battery (1,200Wh) covers 83% of this load.
What Safety Features Does the DEESPAEK 100Ah Battery Have?
- Multi-layer BMS with overcurrent/voltage protection
- Short-circuit auto-shutdown (<0.1s response)
- Flame-retardant ABS casing (UL94-V0 rated)
- IP65 waterproof design for marine/RV use
- Self-discharge rate <3% per month vs. 5-15% for lead-acid
