Wooden Extension 12V Lead Acid Battery Charge PERCENT Capacity Meter LED Tester Voltmeter Digital Battery Tester

With Display switch, which can greatly save valuable battery power. It is not long-term display, the service life is greatly extended. Dual display electricity and voltage at a glance. The display is more intuitive. The upward 8 color bars show the battery power and the downstream voltage meter (display battery voltage), and the voltmeter decimal point automatic shift accuracy is higher. 12V lead acid battery voltage range:(can be used with 4 strings of lithium iron phosphate battery) The battery voltage is greater than 9.7v and is 1 grid The battery voltage is greater than 10.2v, and the battery is 2 grids bright. The battery voltage is greater than 10.7v, and the battery is 3 grids bright. The battery voltage is greater than 11.1v, and the battery is 4 grids bright. The battery voltage is greater than 11.7v, and the battery is 5 grids bright. The battery voltage is greater than 12.2v, and the battery is 6 grids bright. The battery voltage is greater than 12.6v, and the battery is 7 grids bright. The battery voltage is greater than 13.0v, and the battery is 8 grids bright.
