In an electric vehicle, a large number of lithium-ion cells are connected in parallel. While cells in parallel increase the reliability of the battery pack, it increases the probability of current imbalance between the parallel branches, thus ageing gradient. The current peak in a cell also can exceed the maximum charge current capability of the cell; leading to lithium plating,
(Two Redodo''s 12V batteries in parallel) Things to Note Before Charging Batteries in Parallel. To safely charge two batteries in parallel, make sure these batteries are allowed to be connected in parallel.

Parallel lithium batteries have many advantages, including increased capacity, enhanced power output, and improved overall performance. When multiple batteries are connected in parallel, their individual ampere-hour (Ah)
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%.
Connecting batteries in parallel will increase the current and keep voltage constant. Vtotal = single battery voltage (e.g. 1.5V) Itotal capacity = Summation of all batteries current capacity (e.g. 2+2+2=6A) You can use combination of connecting batteries in series or parallel to achieve your desired current capacity and voltage margin.
Understanding Parallel Connections. In a parallel connection, the negative terminals of the batteries are linked together, and the positive terminals are connected to each other.
