Sealed 12V 10Ah LiFePO4 Battery Lightweight LiFePO4 Li Ion Battery Built In Smart BMS

WBDP LK12.8-10 belongs to our cost-effective lead-to-lithium upgrade LiFePO4 series, specially engineered for compact emergency backup power and small off-grid equipment. With standard outer dimensions of 1516594mm and an ultra-light net weight of only 0.81kg, this 12.8V 10Ah lithium iron phosphate battery integrates a full intelligent built-in BMS system. It delivers ultra-stable deep cycle discharge performance, zero maintenance operation and long service lifespan, making it the perfect direct replacement for traditional 12V lead-acid batteries. Widely adopted for mini UPS, emergency lighting, security alarm hosts, solar garden lights and portable standby power equipment, and backed by our industry-leading 5-year warranty for global bulk buyers.

1. Standard Lead-Acid Compatible Size, Plug-and-Play Replacement The 1516594mm shell matches the mainstream installation space of 12V10Ah sealed lead-acid batteries. No cabinet modification, wiring rework or controller replacement required. Customers can directly swap old heavy lead-acid batteries to cut installation and upgrade labor costs drastically.
2. Ultra-Lightweight Compact Body for Flexible Installation Only 0.81kg weight, much lighter than equivalent lead-acid counterparts. Easy single-person handling, suitable for narrow installation spaces inside emergency lights, alarm panels and mini UPS devices without heavy load pressure on equipment housings.
3. Stable & Consistent Discharge Performance for Emergency Backup LiFePO4 cells maintain flat voltage output throughout deep discharge cycles, avoiding sharp voltage drop during sudden power outages. Reliably sustains critical emergency equipment operation to prevent data loss, lighting shutdown or security system failure.
4. Integrated All-Round Smart BMS Safety System The embedded high-precision BMS continuously monitors single cell voltage, loop current and internal temperature. It automatically cuts off charging/discharging under abnormal states to avoid cell damage, short-circuit hazards and thermal risks, fully securing unattended standby equipment.
5. 6000+ Long Cycle Life & Maintenance-Free Operation Delivers over 6000 deep charge-discharge cycles, 5–8 times longer service life than conventional lead-acid batteries. No acid leakage, no corrosion and no regular electrolyte refilling needed, greatly reducing long-term equipment maintenance and battery replacement expenses.
6. 5-Year Manufacturer Warranty & Complete Export Certifications We provide a full 5-year global warranty for all LK series lithium batteries to eliminate customers’ after-sales worries. The battery passes CE, RoHS, UN38.3 and MSDS tests, complying with import regulations across Europe, Southeast Asia, Middle East, Africa and other regions for smooth sea & land freight customs clearance.
