Good and small. I used it as replacement DC-DC converter for Speedway Mini 4 (54V down to 12V). Seems to be working but need further testing when the weather allows.
No cheating. The modules are intact and serviceable. The seller is very nice and honest. I recommend this seller. May God protect him and his children !!!
I connected the modules to the electric scooter. The voltage was 48 volts. I needed to get 12 volts. The LM2596 chips got very hot and burned out. It should not be. This is a marriage. The declared parameters do not withstand the input voltage. Burn out. it is marriage and deception. Attached is a photo of the burnt. I tried to negotiate with the seller, asked him questions, wrote him messages, but he ignores me on purpose. Unfortunately, he left good reviews about him. I do not recommend the seller. Don't buy anything from him !!!
