Remind: the current main board have a charging time detection, 6-7 hours unfinished charge will prompt when the battery is unusual, the default of slow filling is suitable for the battery within 8 ah, quick charge instead of jump line for fit within 15 ah battery, if you want to with larger capacity batteries need to change the timing circuit, the batch can be customized support 20 or more ah Pay attention to: The change is only the charging timeout time threshold, has to do with the charging speed! High power UPS uninterruptible power motherboards developed for 12V 1.5A routers or light cats can also be used for 12V 1A equipment! Charging, need the minimum input 5V, 0.5 0.6A charging current default don't have to change the customer's original-charger, otherwise jump line can improve the charging speed, if the charge is to accelerate the customer original-power supply must be replaced and prevent potential safety hazard, must be at least double the power can Such as customer is using A 12V 1.5A power supply, If you charge quickly, you need to change to 12V 2.5A-3A power supply, need to save more margin, because you have no way to know whether the quality of the power supply is up to standard! Please pay attention to this problem! DC UPS 12V 12W UPS uninterruptible power control main board, used to design routers, switches and other network devices or infrared alarms for continuous power supply. When the battery is fully , it can output a maximum of 1A current. When the battery voltage is about to empty, it can output 8-9W power. Before the battery is empty and shut down, there will often be a flashing reminder. After flashing for several times, it will enter low power protection and close the output! (Tip: input or output interface can be negative, positive can not be shared, battery end can not be negative!)
