Customer ServiceHere''s a useful battery pack calculator for calculating the parameters of battery packs, including lithium-ion batteries. Use it to know the voltage, capacity, energy, and maximum discharge current of your battery packs, whether series- or parallel-connected.
Customer ServiceIn theory, a 6 volt 5 Ah battery and a 12 volt 5 Ah battery connected in series will give a supply of 18 volts (6 volts + 12 volts) and 5 Ah. A 6 volt battery is often three 2 volt cells and a 12 volt battery is usually six 2 volt cells. Therefore, all you have done is connected nine 2 volt cells together to get 18 volts so what''s the problem?
Customer ServiceIn this example, we will consider a 7S lithium-ion battery running a 24-volt AC inverter. A 7S lithium-ion battery has a fully charged voltage of 29.4 volts and a dead voltage of about 18.5 volts. Drawing a 1100W load from the battery pack will require around 37 amps when the battery is fully charged. 1100 watts ÷ 29.4 volts = 37.4 Amps

Customer ServiceBattery packs with well-matched cells perform better than those in which the cell or group of cells differ in serial connection. Quality Li-ion cells have uniform capacity and low self-discharge when new. Adding cell balancing is beneficial especially as the pack ages and the performance of each cell decreases at its own pace.
Assuming the battery pack will be balanced the first time it is charged and in use. Also, assuming the cells are assembled in series. If the cells are very different in State of Charge (SoC) when assembled the Battery Management System (BMS) will have to gross balance the cells on the first charge.
Calculation methodology: The calculator aggregates the capacities of all individual cells within the pack, incorporating the specific arrangement—whether in series, parallel, or a combination. By summing up these capacities, it precisely computes the total capacity of the entire battery pack.
The capacity differences between the two sections are 5, 6, 7 and 12 percent. When cycled, all batteries show large capacity losses over 18 cycles, but the greatest decrease occurs with the pack exhibiting 12 percent capacity mismatch.
Here are a few considerations: Voltage Compatibility: Always match the voltage of the battery with that of the tool. A mismatch can lead to poor performance or damage. Amperage and Run Time: Higher amperage batteries can provide longer run times, but ensure the tool can handle the amperage.
Battery packs that are too large or too small for the tool will not fit properly and can damage the tool or the battery. Different batteries use different chemical compositions, and some are not compatible with certain tools. It is important to choose a battery with the correct chemical composition for your tool.
