12 V Lithium‑Ion Rechargeable Battery — 50,000 mAh (3S2P), DC output, includes 12.6 V charger Key specifications Nominal voltage: 12 V Capacity: 50,000 mAh Cell configuration: 3S2P combination mode Dimensions: 116 × 66 × 20 mm Connector: DC output Charger: supplied 12.6 V charger Why you need this battery High capacity in a compact package: 50,000 mAh provides extended run time for 12 V equipment while the small footprint (116 × 66 × 20 mm) keeps installations neat and lightweight. Safe, reliable power: built‑in Battery Management System (BMS) protects against overcharge, deep discharge, overcurrent and short circuit to extend service life and reduce maintenance. Robust and durable construction: a waterproof PVC outer layer offers insulation, corrosion resistance and wear protection; the inner layer provides low melting point sealing, waterproof adhesion and long‑term integrity. Better alternative to lead‑acid: lithium chemistry delivers lower weight, longer cycle life, higher safety and improved environmental profile compared with lead‑acid batteries. Main features Replaceable 12‑V module: designed for easy replacement or interchange in compatible housings and devices. Integrated BMS: automatic protective management for safer charging, discharging and operation. Waterproof housing: PVC outer shell plus sealed inner layer for improved moisture resistance and mechanical durability. Ready to use: DC connector and 12.6 V charger included for immediate deployment. Performance and compatibility Designed to power 12‑V DC devices that accept a DC connector and 12 V supply. The 3S2P configuration and high capacity make it suitable where long runtime and compact size are required. Lighter and longer lasting than comparable lead‑acid options, reducing weight and maintenance needs in portable and stationary applications. Typical use scenarios 1. Backup power for small 12 V systems — provide reliable runtime for CCTV cameras, routers or network equipment during outages. 2. Portable and field equipment — power measurement instruments, lighting strips or mobile workstations where compact, lightweight energy storage is needed. 3. Replacement/upgrade applications — swap in as a higher‑performance, lower‑maintenance alternative to lead‑acid batteries in small UPS, solar lighting or dedicated 12 V devices. Practical details Physical size: 116 × 66 × 20 mm — confirm device battery compartment or mounting clearance before installation. Connection: DC output — ensure the device connector and polarity match. Charging: supplied 12.6 V charger is matched to the battery; follow the charger and device manufacturer instructions for safe charging and storage. Safety: use the integrated BMS and supplied charger; avoid exposure to extreme heat, open flames or physical damage. This battery delivers high capacity, integrated protection, waterproofed construction and a compact format for reliable 12 V power in portable and fixed installations.
