Specifications:

• Model: RL-BI018
• 3 selectable voltages: 12/24V, 36V, 48V
• 10-segment LED display
• LED battery status indicator
• Automatic sleep mode
• Easy installation using screws or zip ties
• Waterproof IP65
• Certified CE and ROHS.

LED Display Methods Indicating Battery Status

LED glows red – battery voltage is too high or too low

LED glows orange – battery voltage is low, battery should be charged

LED glows green – battery is sufficiently charged

Display Function Indicating Discharge

When discharging, the indicator will move from the tenth line down to the first line every 155 seconds.

(This means when the e-bike goes uphill, the indicator may falsely show a low battery status while it is still adequately charged)

Display Function Indicating Charge

When charging, the indicator will move from the first line up to the tenth line every 200 seconds.

Selectable Battery Types

Using the rotary switch on the back of the meter, 6 types of batteries can be selected. The default type is labeled A.
