Connecting batteries in parallel – BatteryGuy Knowledge Base
There are two ways to wire batteries together, parallel and series. The illustration below show how these wiring variations can produce different voltage and amp hour outputs. In the graphics we''ve used sealed lead acid batteries but the concepts of how units are connected is true of all battery types.

Battery configurations (series and parallel) and their protections
If the device needs an odd voltage, for example, 10 V, then three Li-ion batteries can be connected in series. But when the device needs 8.5 V from Li-ion, you need to know the specifications of your device. If it can handle 10 V, then it can be connected directly; otherwise, a buck or boost is used to achieve 8.5 V.

BQ2947: Combining two battery packs both with BMS
I would like to combine two 3s2p Li-ion packs to make one 3s4p pack. Each of the 3s2p packs utilize the BQ2947 for over-voltage protection and both use the BQ40Z50 to balance cells. If I start with two fully charged cells they may slowly drift apart from each other.

I have two lithium battery packs with separate BMS, Can I connect
It may be successful with an old and new pack but I personally would only join them if the cells had lived similar lives together. Otherwise one pack will just be dumping energy into the other pack to keep them both at the same voltage level.

Understanding aging mechanisms in lithium-ion battery packs:
Batteries were born for electric energy storage because of their high energy conversion efficiency. So far, scientists are still making every effort on the academic exploration of new materials and methods in order to improve battery cell performance [1], [2], [3], [4].Among all types of batteries, lithium-ion batteries are now aggressively entering and are forecasted to

Revitalizing batteries by bringing ''dead'' lithium back to life
Both battery types use positively charged lithium ions that shuttle back and forth between the electrodes. Over time, some of the metallic lithium becomes electrochemically inactive, forming isolated islands of lithium that no longer connect with the electrodes. This results in a loss of capacity and is a particular problem for lithium-metal

Abstract: The lithium-ion battery has become the prevalent technology to store and serve electric power. The state of health (SOH) for a battery cell directly influences the working safety and reliability of the host system. Moreover, since the battery cells are series connected for higher terminal voltage, the cell inconsistency will also impact the performance of the whole battery

How to connect multiple batteries in parallel?
Most of the current will therefore travel through the bottom battery. And only a small amount of current will travel through the top battery. The correct way of connecting multiple batteries in parallel is to ensure that the total path of the current in and out of each battery is equal.
How do you wire a battery together?
There are two ways to wire batteries together, parallel and series. The illustration below show how these wiring variations can produce different voltage and amp hour outputs. In the graphics we’ve used sealed lead acid batteries but the concepts of how units are connected is true of all battery types.
How do you wire a battery in parallel?
Connecting batteries in parallel adds the amperage or capacity without changing the voltage of the battery system. To wire multiple batteries in parallel, connect the negative terminal (-) of one battery to the negative terminal (-) of another, and do the same to the positive terminals (+).
What is a battery pack in a laptop?
This combination of cells is called a battery. Sometimes battery packs are used in both configurations together to get the desired voltage and high capacity. This configuration is found in the laptop battery, which has four Li-ion cells of 3.6 V connected in series to get 14.4 V.
How to wire multiple batteries in series?
To wire multiple batteries in series, connect the negative terminal (-) of one battery to the positive terminal (+) of another, and do the same to the rest. Take Renogy 12V 200Ah Core Series LiFePO4 Battery as an example. You can connect up to 4 such batteries in series. In this system, the system voltage and current are calculated as follows:
