DKV Lead-to-Lithium Energy Storage Battery
DKV Lithium-Replace Lead-Acid Energy Storage Batteries are upgraded solutions designed to replace traditional lead-acid batteries. Available in six standard models (12V5Ah, 12V8Ah, 12V10Ah, 12V20Ah, 12V30Ah, 12V50Ah), capacities range flexibly from 6.4Wh to 640Wh. Built with premium LiFePO4 cells and an intelligent BMS, these batteries enable a quick, plug-and-play swap for existing lead-acid or gel battery setups without modifying the original installation structure. Engineered for reliability, they offer IP65 water and dust resistance, stable operation across a wide temperature range of -20℃ to 60℃, and a cycle life exceeding 4000 cycles (@0.8DOD/25℃/0.5C)—far surpassing the 300-500 cycles typical of lead-acid batteries. Ideal for solar streetlights, UPS systems, surveillance cameras, marine vessels, RVs, and more, these batteries eliminate common lead-acid issues like leakage, short lifespan, and frequent maintenance. Upgrade to DKV for a more stable energy storage system and streamlined operations.

Key Product Advantages
Lead-acid direct replacement with zero retrofit complexity: The enclosure dimensions and terminal positions match traditional lead-acid/gel batteries exactly. No need to replace controllers, inverters, or battery enclosures in existing solar, street lighting, or monitoring systems. Simply remove the old lead-acid battery and install the DKV lithium battery to save significant retrofit costs and construction time.
Lithium Iron Phosphate (LiFePO4) Cell + Intelligent BMS for Safety and Durability: High-quality LiFePO4 cells offer superior thermal stability, minimizing fire or explosion risks. The built-in Battery Management System (BMS) precisely controls charge/discharge limits and provides comprehensive protection against overcharging, over-discharging, overcurrent, short circuits, and overheating. It automatically balances cell voltage to slow degradation and significantly extend the overall battery lifespan.
IP65 High Protection, Ideal for Outdoor Use: The fully sealed enclosure meets IP65 dust and water resistance standards, ensuring reliable operation in rainy conditions, dusty environments, and extreme temperature fluctuations. Perfect for solar streetlights, outdoor security surveillance, and small-scale solar power systems that run year-round with stability.
Ultra-long cycle life reduces long-term costs: With a 80% depth of discharge, the battery delivers up to 6000 cycles with energy retention ≥80%, offering 5-8 times the cycle life of standard lead-acid batteries. Its low self-discharge rate minimizes power loss during extended storage, significantly reducing replacement frequency and lowering long-term maintenance costs.
High compatibility across all devices: Matches standard 12V lead-acid power systems; works seamlessly with most solar charge controllers and off-grid inverters for plug-and-play setup. Supports parallel expansion for flexible energy storage scaling.
Primary Use Cases:
Solar Street / Garden Light Energy Storage: Replace traditional lead-acid street light batteries to extend service life and reduce maintenance replacement frequency.
Security Monitoring Power Supply: Backup power for outdoor cameras, gate access systems, and low-voltage outdoor equipment; ensures continuous operation during power outages.
Small-scale off-grid solar power: residential PV systems, outdoor market stalls, and energy storage for field operations.
UPS Backup Power: Emergency power for POS systems, small office equipment, and routers/switches during outages.
Marine / RV Auxiliary Power: Energy storage for 2V low-voltage systems in small yachts and RVs.
Low-voltage backup power: Emergency supply for small base stations and low-voltage cabinets during outages.
