14.6V 36/50A Lifepo4 Charger Lithium Battery Charger
capacity.Li 14.6V 0–50A Adjustable High-Power Smart LiFePO4 Battery Charger –
750W+ Heavy-Duty Fast Charger for 12V (4S) Lithium Iron Phosphate RV, Marine, Solar & Off-Grid Energy Storage (LED Display, Anderson & Alligator Clips)
Rapidly replenish and maintain your high-capacity off-grid power systems with the capacity.Li 14.6V 0–50A Adjustable Smart Fast Charger (Model: GDDY50A). Purpose-built for high-capacity 12V (4S configuration) Lithium Iron Phosphate (LiFePO4) battery banks, this commercial-grade power supply delivers up to an incredible 50 Amps of continuous current (750W+ peak output), making it one of the fastest charging solutions on the market for RVs, overland rigs, marine vessels, and solar energy arrays.
Featuring an integrated digital LED status display and a manual current adjustment dial (0A to 50A), this charger gives you full control over your charging speeds to match battery manufacturer limits or generator output constraints. Equipped with a 3-stage CC/CV/Trickle charging algorithm, active cooling, and flexible Anderson / Heavy-Duty Clip output leads, it delivers rapid, safe, and efficient power wherever duty calls.
⚠️ Voltage & Wiring Guidance
CRITICAL POLARITY & BATTERY MATCHING:
12V (4S) LiFePO4 SPECIFIC: Calibrated strictly for 12.8V nominal (4S) Lithium Iron Phosphate packs requiring a maximum 14.6V absorption voltage.
Polarity Warning: Ensure absolute correct polarity before turning on power: Red Cable = Positive (+), Black Cable = Negative (-). Reverse connection can cause severe electrical damage.
Adjustable Current Control: Fine-tune charging output from 0A up to 50A to match your specific LiFePO4 battery BMS charge rate limits.
