One basic configuration for charging batteries in series is to connect the positive charger output in red to the positive end of one of the batteries. Video of the day.
Battery Charge And Discharge Power At Multiple Time Scales
How to charge multiple batteries. Figure 1 unbalanced charging a common yet inefficient way of charging batteries in parallel. Insert one cable into the top post connectors cable clamp. This ensures an even charge through all the batteries. Draws 1795 amps draws 131 amps. Begin at one battery. Parallel charging is a fast and cost effective way to charge a lot of lipo batteries at the same time.
Run the cable to the next batterys positive terminal. Tighten the cable clamp with the 716 inch end wrench. You can charge multiple batteries in parallel with just one single charger. Then connect the negative end of the battery to the positive end of the next one and continue to do so for the rest of your batteries. Make a parallel connection of the deep cycle batteries by connecting all the positive terminals together. Is parallel charging risky.
For the final battery connect the negative end of the battery to the negative output in black of the charger. Figure 2 unbalanced charging each battery draws less amperage as power passes through an increasing number of interconnecting leads. Connect a battery charger across the positive terminal of the battery at one end of the row and the negative terminal of the battery at the other end of the row. Parallel charging is also very convenient as it saves you from having to constantly unplug one battery to connect another one to the charger. Number of leads that separate your battery from the charger is equal for each battery. If this is not possible connecting across one battery works but is less efficient.
