Quantifying cell-to-cell variations of a parallel battery module
The impact of parallel strings of battery cells on pack performance has been neglected for many years and only recently identified as one of the critical areas to be considered [1]. Due to the common voltage of the parallel cells, most studies assume that all parallel cells undergo similar currents. In reality the cell with the lowest capacity or highest resistance within

My educated guess is that you are just making a 1S2P pack out of the individual packs. If they are at the same state of charge (voltage), the BMSs should not fight each other unless one of your packs is internally self discharging at a faster rate than the other one. And on that self discharge note, I would also only attempt this if both packs

How to wire multiple batteries in parallel?
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 (+). For example, you can connect four Renogy 12V 200Ah Core Series LiFePO4 Batteries in parallel. In this system, the system voltage and current are calculated as follows:
Can I connect my batteries in series or parallel?
You can connect your batteries in either of the following: Series connection results in voltages adding and amperage remaining the same while parallel connection results in amperages adding and voltages remaining the same. Series-parallel connection results in both voltage and amperage adding.
How do parallel batteries work?
The basic concept is that when connecting in parallel, you add the amp hour ratings of the batteries together, but the voltage remains the same. For example: two 6 volt 4.5 Ah batteries wired in parallel are capable of providing 6 volt 9 amp hours (4.5 Ah + 4.5 Ah).
Should I jumper the batteries in parallel?
In the eg4 manual it says not to jumper the batteries in parallel, rather use a properly rated busbar to connect them in parallel to avoid large currents and overheating in the end wires. So my question is this: In my case because its only 2 batteries, can I just connect 2 negative wires to the battery end of the smartShunt?
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:
What happens if you charge a rechargeable battery in parallel?
for secondary (rechargeable) batteries – the stronger battery would charge the weaker one, draining itself and wasting energy. If you connect rechargeable batteries in parallel and one is discharged while the others are charged – the charged batteries will attempt to charge the discharged battery.
