CYGEREEN 36V 3A Smart LiFePO4 Battery Fast Charger

43.8V Output for 12S Lithium Iron Phosphate (LFP) Packs (132W High Power, Universal AC 100-240V Input, CE/RoHS Certified) 

Optimize and protect your energy storage setup with the high-efficiency CYGEREEN 36V 3A Smart LiFePO4 Fast Charger. Engineered specifically for 12S 36 Volt Lithium Iron Phosphate (LiFePO4 / LFP) battery packs, this charger delivers a precise 43.8V maximum output voltage at a steady 3A charge current, providing up to 132W of continuous charging power.

Designed for e-bikes, electric mobility scooters, trolling motors, and custom solar energy storage systems, the CYGEREEN SJT150E utilizes an intelligent multi-stage Constant Current / Constant Voltage (CC/CV) algorithm. This ensures your LiFePO4 cells reach a full 100% state-of-charge quickly while actively preventing thermal degradation and extending overall cell life.

⚠️ Chemistry & Voltage Matching Notice

CRITICAL BATTERY CHEMISTRY & VOLTAGE GUIDE:

  • LiFePO4 / LFP Only: This charger is engineered EXCLUSIVELY for 12S Lithium Iron Phosphate (LiFePO4) battery chemistry (3.2V nominal per cell x 12 = 38.4V nominal / 43.8V full charge cutoff).

  • DO NOT USE ON STANDARD LITHIUM-ION: Never use this charger on standard 36V (10S) Li-Ion / NMC batteries (which require a 42.0V cutoff) or Lead-Acid / AGM batteries.

  • Universal AC Power: Supports broad 100-240VAC 50/60Hz input ranges for global deployment.

🚀 Key High-Performance Features

  • Precise 43.8V Cutoff Voltage: Tailored specifically for 12S LiFePO4 cell chemistry to ensure safe, complete charge cycles without overcharging individual cells.

  • 132W Fast Charging Output: Delivers a continuous 3A current for rapid replenishment of 20Ah+ LFP battery packs with minimal heat generation.

  • Intelligent CC/CV Multi-Stage Protection: Automatically monitors charge parameters to guard against short circuits, over-voltage, over-current, and thermal overload.

  • Multiple Output Port Options: Compatible with standard DC barrel, XT60, and Heavy-Duty Alligator Clip connection configurations.

  • CE & RoHS Certified Quality: Fully compliant with strict European and international electrical safety and environmental standards.

⚙️ Operating Instructions & Sequence

  1. Verify Chemistry: Confirm your battery pack is a 12S LiFePO4 / LFP configuration requiring a 43.8V full-charge threshold.

  2. Step 1 (DC Connection): Plug the charger's output connector (DC, XT60, or Alligator Clips) firmly into your battery's charging port.

  3. Step 2 (AC Connection): Connect the AC power lead to a wall power outlet (100–240V AC).

  4. Completion: When charging is complete, the smart internal circuit automatically terminates power delivery to prevent overcharging. Unplug the AC power lead before disconnecting the DC leads from your battery.
