5pcs 3.7V 9V 5V 2A Adjustable Step Up 18650 Lithium Battery Charging Discharge Integrated Module
A part of the review has been auto-translated.
Funciona bem, testei um com uma bateria 18650 e outro com duas em paralelo, perfeito, só recomendo cuidado no trimpot que faz saltos de voltagem complicados de se monitorar
Well packaged, received in good condition and excellent delivery time (13 calendar days from order).
I have buy the item because it was very interesting but testing it I can not get the desired output. for example I have set output to 12v but just with a little load the voltage drop to 5-6volts. The output declared from banggood are not true/real for me.
An Amazing Product I'ii buying Again!!!!
All modules compatible OK!!!
Nifty module that can charge LiIon battery and simultaneously provide 3.7-27v output for my many projects, great product!
Fragile packaging, had no bubble plastic, too risky not to have damaged the parts.
super cheap
all working well, nice module
good
