Parallel wiring is a method of connecting multiple lithium leisure batteries with the aim of achieving higher overall capacity, while keeping the voltage the same as a single battery. By connecting the positive terminals of each battery together and the negative terminals together, you can effectively increase the amount of charge the batteries can hold.
The batteries are 18,650 lithium-ion cells with a nominal capacity of 2000mAh. In particular, three groups of four lithium-ion batteries (B0005, B0006, B0007, and B0018) are selected. The batteries are charged and discharged at room temperature (24 °C), with a charging current of 1.5 A until the voltage reaches 4.2 V.
Accurate state of health (SOH) estimation is critical for lithium-ion battery maintenance and safety. Currently, numerous time series models based on deep learning have been applied to online prediction of SOH. However, the strong nonlinear coupling between different sample data seriously interferes with the estimation accuracy of the existing models.
Lithium-ion battery state-of-health (SOH) monitoring is essential for maintaining the safety and reliability of electric vehicles and efficiency of energy storage systems. When the SOH of lithium-ion batteries reaches the end-of-life threshold, replacement and maintenance are required to avoid fire and explosion hazards.

MY own personal rule is two batteries, 150% current of one battery. So with two batteries each capable of 100 amps, with 2 in parallel, you can pull 150 amps, so even if there is a 50 amp difference, the high battery is only at 100 amps, and the low one is providing the other 50 amps. Go to 4 batteries, and now you should be safe pushing 225%.
