Why Choose Capacity.Li?

50A High-Current Output

0–50A fully adjustable current. Ultra-fast charging for 12V LiFePO4 batteries — charge a 100Ah battery in just 2 hours.

Precision CV/CC Charging

Professional constant-voltage / constant-current charging mode. Current increases gradually until full charge voltage of 14.6V is reached — extends battery lifespan.

Universal AC Input

AC 100–240V input. Works worldwide with EU, US, AU, and UK power outlets — no adapter needed.

Smart LED Display

Real-time monitoring of voltage, current, power, and charging status. Know exactly what's happening at a glance.

Built-In Cooling Fan

Active fan cooling for continuous operation. Protects both charger and battery during extended fast-charging sessions.

Factory Direct Warranty

2-year warranty, 30-day money-back guarantee, free shipping, and lifetime technical support.

Electrical Specifications

Three Output Modes

🔋
LiFePO4 Mode
Optimized for 12V LiFePO4 batteries. 14.6V full charge voltage. Short-circuit and over-voltage protection.
⚡
CC/CV Charging
Professional constant-current / constant-voltage charging. Current increases gradually — extends battery lifespan.
🛡
5-Layer Safety
Over voltage, over temperature, over current, over time, and short circuit protection. Full safety coverage.

Built-In Safety Protection

🛡
Short-Circuit Protection
Auto constant-current mode on short circuit
🌡
Over-Temperature Protection
Thermal shutdown with active fan cooling
⚠
Over-Voltage Protection
Automatically stops at 14.6V full charge

Note: Always verify positive (+) and negative (−) connections before use. Red = Positive, Black = Negative. Reverse polarity may cause damage.

How to Connect

1
Connect to AC Power
Plug in the AC power cord. The universal 100–240V input auto-detects your local voltage.
⚠ Ensure the AC outlet matches your country's standard (EU/US/AU/UK).
2
Set Current
Adjust the output current to match your battery's requirements (0–50A). Voltage is fixed at 14.6V for LiFePO4.
⚠ Do not exceed your battery's recommended charge rate.
3
Connect the Battery
Attach the connector to your battery terminals. Red = Positive (+), Black = Negative (−).
⚠ Do NOT reverse polarity. Reverse connection will cause damage.
4
Start Charging
The charger enters constant-current (CC) mode. Current increases gradually until 14.6V is reached, then switches to CV mode.
