ZK-BC 4.5-32v 12v 24v Lead-acid Lithium Battery Voltmeter Ammeter 18650

RM1307731646748235

note:

1. The power meter defaults to 12V battery mode. Other specifications of the battery need to be set by ons.

2. The USB port fast charge function requires mobile phone cooperation and cannot be activated every time. If it cannot be activated, please plug and unplug a few times. The uses In IP6505T, and the circuit is also recommended by the manufacturer. The supports mainstream fast charge protocols, but cannot support all the fast charge protocols on the market. Because fast charge is related to many factors such as mobile phone data lines, mobile phone models, mobile phone power, and protocol matching degree, it cannot guarantee that every mobile phone can charge fast Or you can charge fast every time. 产品

Product selling points

Battery description

Please select the corresponding option according to the type of your battery and the number of cells in series. Ordinary lithium batteries and ternary lithium batteries are generally nominally 3.7V / cell and fully charged to 4.2V. The lithium-ion battery is generally nominally 3.2V / cell and fully charged with 3.7V. Lead-acid batteries are generally rated at 12V / block and are charged at 13.8V-14.5V.

Ternary lithium battery

The battery voltage is greater than N × 3.21V + -1%, and the power is on for 1 grid (Note: N is the number of battery cells, N = 2-7)

Key function description

1.Control the backlight

Short pre-switch the backlight on or off

2. Set the battery type and number of strings (only the battery type and number of strings can be displayed correctly)

1. Pre and hold the on for more than 3 seconds to switch to the battery selection interface Barrery.

In the battery type interface, short pre to select the battery type. The battery type can be switched between Pb12V / Li3.7V / Fe3.2V

Pb12V--12V lead-acid battery

Li 3.7V-ternary lithium battery

Fe3.2V-lithium phosphate battery

2. After selecting the battery type, pre and hold the on for more than 3 seconds to switch to the number selection interface for battery strings.

On the battery string number interface, short pre to select the battery string number NS (N stands for string number)

12V lead-acid battery--N = 1/2

Ternary lithium battery-N = 2/3/4/5/6/7

Lithium phosphate battery-N = 2/3/4/5/6/7/8

3. After selecting the number of battery strings, pre and hold the on for more than 3 seconds to return to the normal interface.
