Can two lithium battery cells with different capacities be used in parallel?portable battery generators

　　For example, if the current limiting module of a lithium-ion BMS is 10 A, and the reverse charging current is 50 A or greater when connected in parallel, the parallel module will limit 50 A and only allow 10 A of current to flow into a lower voltage lithium-ion battery pack.

　　Especially when two batteries have different capacities, the voltage during use is also different.

　　Note: Please confirm if there is a current limiting module on the protection panel of each set of lithium batteries. If not, please add it again.

　　Alternatively, a parallel balancing module can be installed outside the battery pack line in the middle of two battery pack lines

　　This method is actually the best method and has the best effect, but the cost is too high.

　　It is to add a parallel balancing module on the line where two sets of lithium battery packs are connected in parallel. The balance module utilizes a combination of software and hardware to automatically identify the voltage of two sets of lithium battery packs. When using, the first thing to do is to use a high voltage lithium battery pack. Only when the voltage of the high voltage lithium battery pack drops and is the same as the voltage of the low voltage lithium battery pack, will both battery packs be powered simultaneously.

　　Two sets of lithium batteries are on the same line, each independent and supplying power to the load, without the phenomenon of reverse charging from high voltage to low voltage when connected in parallel
