Review on Anmbest XH M609 Undervoltage Protection Overdischarge by Javarie Brumfield

I was so excited when my module arrived. I was disappointed when I installed it. NO output voltage. I've tried different settings with no positive results. I have to admit, it's very easy to set the cutoff voltage and the voltage at which you want the output power to recover (cause of the second star). Looking more closely at the components, I saw a resistor (102) that was either defective or badly connected. Update: As soon as the seller became aware of my issue, I received an immediate refund. I would have liked a replacement but this item was sold out. I have bought other products from them and they all work well. I will buy from them again. I think it was a small factory error.
