12V 50Ah Deep Cycle LiFePO4 Lithium Iron Phosphate Battery (Integrated BMS, 4000+ Cycles, M8 Terminals, IP65)

Product Overview

The LTI12V50AH 12V 50Ah Deep Cycle Lithium Iron Phosphate (LiFePO4) Battery is an industrial-grade energy storage solution engineered to replace traditional, heavy 12V sealed lead-acid (SLA) and AGM batteries in critical backup, solar, and mobile power systems. Delivering 640 Wh of usable continuous energy, this battery provides up to 100% Depth of Discharge (DoD) without cell degradation. It offers a lightweight, high-energy-density alternative optimized for telecom power enclosures, off-grid CCTV surveillance trailers, RV auxiliary systems, marine vessels, and emergency UPS backups.

Built with premium automotive-grade Grade-A LiFePO4 prismatic cells, the LTI12V50AH incorporates an intelligent internal Battery Management System (BMS) that continuously monitors and protects against overcharging, deep over-discharging, over-current, short circuits, and extreme thermal fluctuations. Delivering over 4,000 deep discharge cycles at 80% DoD—over five times the lifespan of standard lead-acid units—it maintains a flat voltage discharge curve for sustained electrical delivery. Encased in a rugged, sealed IP65-rated ABS housing with M8 threaded terminal posts, it supports series and parallel configurations (up to 4S4P) to easily build 24V, 36V, or 48V energy banks.

✅ Key Features

• 4,000+ Deep Duty Cycles: Offers 4,000 to 15,000 discharge cycles (depending on DoD), significantly reducing lifetime maintenance and replacement costs.

• Integrated Smart BMS Protection: Automatic internal cutoff protects against over-charge, over-discharge, over-current, short circuit, and low/high temperature conditions.

• 100% Usable Capacity (640 Wh): Provides twice the usable power of a standard 50Ah lead-acid battery, which degrades if discharged past 50%.

• Ultra-Lightweight & Compact: Weighs approximately one-third of an equivalent lead-acid/AGM battery, facilitating single-person installation and reducing structural load.

• Series & Parallel Expansion: Supports up to 4 units in series (up to 48V) and up to 4 units in parallel (up to 200Ah) for customizable power arrays.

• Rugged IP65 Waterproof Casing: Sealed flame-retardant ABS enclosure resists dust, moisture, salt air, and mechanical vibration.

• Universal M8 Threaded Terminals: Heavy-duty M8 copper-plated terminal posts ensure low-resistance, vibration-proof electrical connections.

• Eco-Friendly & Maintenance-Free: Contains no toxic heavy metals (lead, cadmium) or hazardous acid liquid; can be mounted in any orientation without leaking.
