Using the Bluetti 12v/24v Lead-acid Battery Charing Cable, you can connect a separate 12v/24v lead-acid battery to the Bluetti EB200 or the AC200P. This will temporarily increase the battery capacity of the Bluetti ÈB200/AC200P, extending the battery lifetime. When connected to the Bluetti, the lead-acid battery will charge the EB200/AC200P.
If you would like to use the Bluetti 12v/24v Lead-acid Battery Charging Cable, you first need to change the settings of the EB200 or the AC200P. To do so, open the settings on the display. Then, you can change the DC Input Source from "PV" to "auto mode". When the Bluetti EB200 or AC200P is set to the "auto mode", the maximum current is 8,2A. The EB200/AC200P are also equipped with a safety mechanism to prevent overcharging.
Please note, the red clamp is the positive pole and the black clamp is the negative pole.
