Ok, so I've done some more research on the matter and apparently my quetions have been answered in older posts. Custom solution 1 Custom solution 2 Custom solution 3 Complete IC solution So, to answer my own questions, 1)The rest of the load should be located before the battery charger IC like in custom solution 3, in order to be considered a load. 2a) ...

The LM2596 is a 3A regulator. At max load it is 73% efficient, which is kind of low for a DC-DC, so it will be shedding 4W between the regulator and other losses. That’s a tremendous amount of heat, so the regulator is going into thermal shutdown to protect itself. What is the load for each motor? I could easily imagine that with a large number of them, ...

Depending on the actual package for your regulator, the total power dissipation will be limited to something less than a watt. Trying to dissipate more power than this in the regulator will cause it to overheat. To be on the safe side, you should probably limit the power to about 0.5W. So with 19V across the regulator you don't want to draw more than about ...

The TP4056 has a Vinmax of 8V and can be safely operated, if desired, at 6V input. TP4056 datasheet here PV panel voltage regulation: A reason to limit Vin is that the IC will charge at a decreasing maximum current as Vin increases due to thermal dissipation issues. Charging specifications are given at Vcc = 5V (datasheet page 1) so limiting Vin to 5VDC ...

Tipically the initial constant current ionizes the battery chemistry and the voltage cycle adds the potential. if the charger has no enough current thevoltage cycle may find larger resistance and thus try to push more voltage than battery requires causing trouble. Charger is supposed to have plenty of current for the initial chemistry cycle at LiPos..

mAh capacity of a battery shows how much charge it can hold (its maximum capacity). It does not specify how much current you can draw from it. You can use the 1200mAh battery in your 400mAh Arduino project without any hazard. Just make sure that the current you are drawing from the battery, does not exceed its maximum current discharge rating. To ensure that ...

If I have understood everything correctly, you are safe with the 1200mAh battery. The nominal voltage is the same. The higher capacity is also an advantage. The C Rating is simply a measure of how fast the battery can be discharged safely and without harming the battery. (https://rogershobbycenter.com/lipoguide) This means with the 1200mAh battery, can ...

I realized that the lipo had a protection circuit, charging it completly with a correct voltage solved the problem.
