Here''s the deal. It is crucial to determine how to charge multiple batteries with one solar panel because the amount of energy dispensed depends on this particular number. The batteries connected to the solar panel are placed parallel. This way, the battery retains the same voltage but doubles its energy capacity.
This will allow you to use higher voltage amounts in applications that demand a lot of power. Connect Batteries in Parallel. When you connect batteries in parallel, like connecting 3 batteries in parallel, you are connecting batteries to ramp up the amp-hour capacity. The connection capacity will increase, but the voltage will not.
Now you can indeed put all your 18650s in parallel. Power banks do it all the time. However, unless your load has its own over voltage and under voltage protection, you should place a lithium-ion protection circuit between the batteries and the load. Capacity is basically how long you can supply a current. I.e. a 5 Ah cell can supply 5 amp
