| Peak Discharge | 200A (5 seconds) |
| Charge Efficiency | 99% |
What Safety Mechanisms Protect the DEESPAEK Battery?
Multi-layered protections include cell-level voltage monitoring, temperature-triggered charge current reduction, and automatic shutdown during short circuits. The flame-retardant casing (UL94-V0 rated) prevents thermal runaway. Reverse polarity protection safeguards against wiring errors, while the steel frame absorbs impact forces up to 500G.
The battery’s multi-stage protection system operates on both hardware and software levels. The BMS continuously monitors individual cell voltages, disconnecting the load if any cell exceeds 3.65V or drops below 2.5V. For thermal management, dual NTC sensors regulate charging currents—reducing to 0.2C when temperatures exceed 45°C. The casing undergoes rigorous testing, including 24-hour salt spray exposure and 1.5-meter drop tests, to ensure durability in harsh environments.

| Overvoltage | Disconnects at 15V |
| Undervoltage | Shuts down at 10V |
| Short Circuit | 0.05ms response time |
How Does the DEESPAEK 12V 100Ah LiFePO4 Battery Work?
This battery uses lithium iron phosphate (LiFePO4) chemistry, which stabilizes electron flow for consistent voltage output. Its built-in Battery Management System (BMS) prevents overcharge, over-discharge, and short circuits. The LiFePO4 cells operate efficiently between -20°C to 60°C, making them suitable for extreme climates while retaining 80% capacity after 4000 cycles.
Why Choose LiFePO4 Over Traditional Lead-Acid Batteries?
LiFePO4 batteries provide 4x the cycle life, 50% weight reduction, and 95% efficiency compared to lead-acid. They charge faster, require no maintenance, and remain operational at partial states of charge. Unlike lead-acid, they emit no fumes and have a lower total cost of ownership despite higher upfront pricing.
Where Can the DEESPAEK 12V 100Ah Battery Be Used?
Applications include off-grid solar setups, electric vehicles, marine trolling motors, RV house batteries, and backup power systems. Its vibration resistance and corrosion-proof terminals make it ideal for mobile use. Solar installers particularly favor its 200W solar panel compatibility for full recharges in 6-8 hours.
How to Maintain the DEESPAEK LiFePO4 Battery for Maximum Lifespan?
Store at 50% charge in dry, cool environments when unused. Use a compatible LiFePO4 charger (14.4V–14.6V absorption voltage). Avoid deep discharges below 10% capacity. Clean terminals quarterly with dielectric grease. Recalibrate the BMS annually via full discharge/recharge cycles. Firmware updates via Bluetooth optimize performance as new features release.
How Does Temperature Affect the Battery’s Performance?
Below -10°C, charging efficiency drops by 30%, requiring optional self-heating models for arctic use. High temperatures above 45°C activate fan cooling via the BMS, reducing charge speed to prevent degradation. Discharge performance remains stable across all temperatures, with only a 5% capacity loss at -20°C.

FAQs
- Can this battery power a 2000W inverter?
- Yes, when paired with a 2000W inverter, it delivers 1200W continuous power (100Ah × 12V × 1C rate). For higher loads, parallel multiple units.
- Is it compatible with existing lead-acid chargers?
- Only if the charger has a LiFePO4 mode. Standard lead-acid chargers may overvolt the cells, voiding the warranty.
- Does it require ventilation?
- No—unlike lead-acid, it produces no gases. Sealed installations in compartments are safe.
