descriptions 1. Measuring voltage 0-120V, measuring current 0-100A/400A/600A, measuring capacity 0~9999.99AH;2. Applicable to various batteries, such as ternary lithium batteries, lead-acid batteries, lithium iron phosphate batteries, etc.;3. 2.4-inch high-definition color display, silicone buttons;4. The sampler is equipped with a shell, which is easy to install and provides insulation protection;5. The shunt is made of pure copper material, which has good conductivity and will not consume too much battery power in standby mode;6. It can automatically identify charging and discharging, the charging capacity increases, the discharging capacity decreases, remaining capacity is displayed in real time;7. It supports setting two different screen brightnesses during the day and night, and can freely switch between three off-screen modes.8. Overvoltage, undervoltage, overcurrent, overpower, external overheating, low temperature protection can be set. When the protection condition is reached, there will be an alarm sound and a pop-up window reminder, and the relay will disconnect the circuit (the delivery list does not include the relay);9. Provide mobile APP, support Android and Apple mobile phones to view data through Bluetooth, view charge and discharge curves, and support historical data export;10. Provide communication protocol, use 485 communication to control the instrument;<img data-srcid="-" src="https://image.doba.com/dgd1-WobPDYQzFJce/dc-120v-400a-battery-tester-battery-monitor.jpg" alt="dropship DC 120V 400A Battery Tester Battery Monitor" /><img data-srcid="-" src="https://image.doba.com/dgd1-lwqpbdvGBPcg/dc-120v-400a-battery-tester-battery-monitor.jpg" alt="dropship DC 120V 400A Battery Tester Battery Monitor" /><img data-srcid="-" src="https://image.doba.com/dgd1-WODSVcFUQYPe/dc-120v-400a-battery-tester-battery-monitor.jpg" alt="dropship DC 120V 400A Battery Tester Battery Monitor" /><img data-srcid="-" src="https://image.doba.com/dgd1-lIvdVNbbAYcr/dc-120v-400a-battery-tester-battery-monitor.jpg" alt="dropship DC 120V 400A Battery Tester Battery Monitor" /><img data-srcid="-" src="https://image.doba.com/dgd1-rTDeVJQCFoPC/dc-120v-400a-battery-tester-battery-monitor.jpg" alt="dropship DC 120V 400A Battery Tester Battery Monitor" /><img data-srcid="-" src="https://image.doba.com/dgd1-AbvHqeQCBcoJ/dc-120v-400a-battery-tester-battery-monitor.jpg" alt="dropship DC 120V 400A Battery Tester Battery Monitor" />
