Lztsuply 36V 20A LiFePO4 Battery Charger | IP67 Waterproof, 0V Rescue, M8 Ring Terminal

Meet the Lztsuply 36V 20A LiFePO4 Battery Charger, designed for rugged outdoor use and demanding on‑the‑go charging needs. This sealed charger supports 36V systems and works with 43.8V LiFePO4 batteries, making it suitable for golf carts, RVs, boats, forklifts, and home charging setups. Its IP67-rated enclosure, cooling system, and smart electronics are built to perform in harsh environments while maintaining reliable charging behavior.

All-round Security Protection

Your charging setup benefits from multiple safeguards that help protect both battery and device. Features include reverse polarity protection, output short circuit protection, overvoltage protection, and battery isolation protection. The charger also carries FCC, CE, and RoHS certifications, backed by dependable hardware and software designed for stable operation and long service life.

• Reverse polarity protection to prevent accidental damage
• Output short circuit and overvoltage protection for safety
• Battery isolation protection and certified hardware/software integration

High-Efficiency and Stable Charging

Charging is managed with precise constant current and constant voltage phases for quick yet controlled power delivery. A rugged cooling fan reduces heat buildup, and the IP67 waterproof rating supports use in challenging locations. An NTC temperature sensor continuously monitors temperature to help guard battery health.

• Constant current/constant voltage charging for stability
• Rugged cooling fan and IP67 protection for tough environments
• NTC temperature monitoring for proactive safety

Easy Connection Options

Connectivity is designed for flexibility. A long 300 cm US plug input, a reliable 100 cm M25 connector, and a 50 cm M25 to M8 ring terminal adapter enable straightforward integration with different battery types or devices.

• Long input cord for flexible placement
• Standard M25 connector with a convenient M8 ring terminal adapter
• Supports multiple battery configurations with minimal setup

Newly Upgraded Trickle+Pulse Charging

The charger operates in four stages to optimize safety and battery health. Early charging uses a gentle current for deeply discharged packs, then a small current maintains near-full charge to prevent overcharging. The intermittent high‑frequency pulse maintenance can boost capacity recovery for certain battery chemistries, potentially extending usable life.

• Stage 1: gentle initial current for safety
• Stage 2: controlled replenishment as charge nears completion
• Stage 3: pulse maintenance to support capacity retention
• Stage 4: stabilizing finished charge to preserve battery health

0V Battery Rescue Function

With coordinated control and smart sensing, the unit can wake and pre-charge deeply discharged batteries, bringing them toward a safe charging regime. Real-time voltage and temperature monitoring help keep the process controlled. Note: heavily damaged, bulged, or very low voltage packs may require replacement.

• Pre-charging to revive deeply discharged packs
• Real-time voltage and temperature closed-loop control
• Clear guidance on battery health and limitations

Warranty and Support

Thoughtful design details include a sealed, heat‑dissipating aluminum housing, glued internals for dust and water resistance, and robust performance in harsh environments. The product comes with a detailed manual and fault diagnostic checklist, plus a 24‑month warranty for added peace of mind.

Key specs include dimensions of 9.06"D x 5.31"W x 2.98"H and a weight of 6.61 lb, with noise levels kept under 35 dB.
