If the current value is positive, it means that the batteries are charging. Note: if the current value is negative, it means that the batteries are feeding the Raspberry Pi. The terminal will print the IP address, battery voltage, current, and the percentage of battery quantity, as well as the CPU, GPU and memory information after starting the server. Open a terminal and run the following commands: Should be placed carefully and properly, keep it away from inflammables and explosives articles, away from children, avoid any safety accident caused by careless storage.Should be replaced with new ones when the batteries reaching their max cycle life, or working over two years, whichever comes first. Lithium batteries have limited cycle life, they will also deteriorate as time goes by.Choose batteries from formal manufacturer, and ensure the batteries will work stably and safely by aging test. We had a 15 year old Mastervolt battery monitor but it didnt feel true and it wasnt at the right place in the boat. When buying Lithium battery, should always make sure the battery specification is compatible with the expansion board.Do not mix use old batteries with new ones, avoid using batteries of different brands.Do not use inferior charger/charging panel to recharge the battery. Do not reversely connect the polarities when recharging or discharging the battery.They may cause fire, personal injury, or property damage, if they're not properly recharged or used. Li-ion and Li-po batteries are quite unstable.If the working current required by Raspberry Pi is too big, it may cause over-current and low-voltage problem and the Pi may keep rebooting. Note 3: The discharge current is about 1.8A if the battery was fully charged, and it gets smaller as the battery voltage. Note 2: The board may not work when you mount the batteries for the first time, you need to charge batteries on board for a while to activate them. Note 1: Please turn the power switch to OFF before you connect the battery, or the board may be damaged because of shorting.
