However, if you have longer wire lengths or higher amperage ratings, you may need to use a thicker wire gauge such as 6 or 4 gauge. It is important to note that using a wire gauge that is too thin can cause the wire to overheat and melt, causing a fire hazard. On the other hand, using a wire gauge that is too thick can be costly and unnecessary.

Wiring lithium-ion batteries in series is simple. It's as simple as connecting the positive connection of the first cell to the negative connection of the next cell. Some configurations will require just 3 cells in series, other configurations require 20 or more.
If you are doing parallel connections, you need a larger cable. However, if you installing series connections, you require a smaller cable for a similar power load. Learn how to choose the right battery cable size, including types, gauges, capacity, and common mistakes, with detailed size charts.
Each lithium battery in the bank is a 51.2Vn 30AH lithium battery with a BMS capable of managing 30A of continuous charge or discharge current. By connecting 4 x 51.2V 30AH batteries in parallel each string becomes a 51.2V 120AH string capable of handling up to 120 amps of continuous current.
Either way, once you wire a set of lithium-ion batteries in series, it will form an open-ended chain. At the ends of the chain, you will find your main negative and positive connections. When battery cells are wired in series, their voltages are added but their amp hours are not.
Charging lithium battery cells while they are in a series configuration is not only possible but very common. It's how ebike, laptops, and just about any other battery chargers work. When charging lithium batteries in series, the charge voltage is divided among the number of cells in series.
