The battery capacities are listed as 2x1000mah and 2x1200mah.
Lithium battery balancing
Do you know what brand of battery and what brand of charger you have? Its likely your charger is doing too high of voltage. If you read these threads people think they need 14.4v to charge a lithium battery. To me its the opposite. 14.4v is too high and never gives the BMS a chance to balance the batteries. Gets worse over time as you have noticed.
Putting lithiums in parallel, balance first?
As for charging, the 40% battery will charge (from the charger and the other battery). At some point the 40% battery will hit about 75% and the 98% battery SOC will be drawn down to about 75%. Again, this will involve the BMSs switching on and off until the two batteries are close to being of equal SOC. Again, not what the BMSs is designed to do.

6 FAQs about [Lithium battery parallel charge balancing]
How to balance lithium batteries in parallel?
Balancing lithium batteries in parallel involves measuring each battery's voltage before connection, ensuring they're within an acceptable range of each other, and then connecting all positive and negative terminals together. What Does It Mean For Lithium Batteries To Be Balanced?
Can You charge a lithium ion battery in parallel?
Charging cells in parallel is not much different than charging them on their own. For example, if you have a single lithium-ion cell that has a max charge voltage of 4.2 volts and a max charge current of 2 amps, you can use those same settings to charge a battery that has 3, 20, or even 100 of those battery cells in parallel.
Does a lithium ion battery have a balance problem?
If you built a lithium-ion battery and its capacity is not what you expect, then you more than likely have a balance issue. While it's true that cells connected in parallel will find their own natural balance, the same is not true for cells wired in series. Battery cells in series have no way of transferring energy between one another.
What is balancing lithium battery packs?
Balancing lithium battery packs, like individual cells, involves ensuring that all batteries within a system maintain the same state of charge. This process is essential when multiple battery packs are used together in series or parallel configurations.
What is battery balancing?
Battery balancing refers to the process of ensuring all individual cells or groups of cells within a battery (or multiple batteries in a system) maintain the same voltage levels. In lithium batteries, maintaining balance is crucial because it allows for the most efficient use of the battery's total capacity.
Do batteries balance in parallel?
The quick answer is yes, batteries will balance in parallel. However, there are a few things to keep in mind when connecting batteries in parallel. First, it’s important to make sure that the batteries being connected are of the same voltage and capacity. If they’re not, then you risk damaging the battery with the lower voltage or capacity.
