Battery Level Indicator DC5-30V 12V24V Ternary Lithium Battery Lithium Iron Phosphate Lead-Acid Battery Capacity Display Tester
 
Product selling points:
1. The product defaults to a ternary lithium battery L03 S voltage (L03) when powered on for the first time.
2. Measurement of ternary lithium battery (L): from L03 S to L12 S.
3. Measurement of iron lithium battery (F): from F03 S to F14 S.
4. Acid battery (P) measurement: P12V/P24V/36V/48V.
5. Custom mode: high and low voltage settings, set the voltage values for fully charged and fully discharged.
6. Low voltage alarm function: When the battery level is equal to or lower than 10%, the red battery grid flashes.
7. There is a power-off memory storage function.
