Frequently Asked Questions - GS950C-3601800 Vevor

What to do if the charger does not start and the status LED flashes red?

Check the polarity of the DC terminals: positive and negative must be correctly connected. If the battery is defective, replace it. If the problem persists, the charger must be returned to the dealer.

How to select the correct battery type before charging?

Use the battery type selector on the charger. Press to cycle through types: lead-acid (green LED), LiFePO₄ (red LED), or ternary lithium (orange LED). Ensure you select the correct type to avoid any risk of fire.

What does a status LED flashing 2 times per second mean?

This indicates a short circuit. Disconnect the charger and check the battery. If the fault persists after replacement, the charger must be repaired by a professional.

What types of batteries can I charge with this model?

The GS950C-3601800 charger can charge lead-acid, lithium iron phosphate (LiFePO₄), and ternary lithium batteries, all at 36 V.

How to interpret the status LED during charging?

Solid red: charging. Solid green: charging complete (float). Alternating red and green: poor contact. Flashing red (1 time/s): battery depleted. Refer to the flashing code table for other faults.

Can I leave the charger plugged in permanently?

It is recommended to unplug the charger after use or once charging is complete. First disconnect the AC cord, then the DC terminals.

What to do if the status LED flashes 5 times per second?

This indicates charger overheating. Let it cool down in a ventilated area. The charger will automatically resume operation when the temperature drops.

Is it safe to charge outdoors or in a damp place?

No, charge only in a dry indoor space, well-ventilated and away from moisture, high temperatures, and flammable gases.

How to clean the charger?

Before any cleaning, disconnect the charger from the battery and mains. Regularly clean dust from the vents and fan with a dry or alcohol-dampened cloth.
