Cllena 24V to 12V 20A 240W Step Down Converter Voltage Reducer Waterproof DC/DC Buck Transformer Regulator Power Supply Module

excelente

Working well on my pontoon for three seasons. Connected to 48V DC Lifepo4. Powers Seamax PowerMax Brush-less Electric Trolling Motor, 2HP 12V and fish finder.

My Bluetti AC200 and AC200P 'solar generators' will charge at 100 watts from a 12v source OR 200 watts if from a 24v source. I had a LiFePo4 280ah 12v pack set up that has gobs of power but would take forever to charge the Bluetti at 100 watts.I figured if I could boost the voltage from the LiFePo4 pack to 24v, then I could supply the Bluetti with 200 watts of recharge when it needed it. The large LiFePo4 battery pack is charged by 1500w of solar so it had plenty available.In short, it worked like a charm! This device supplied 204 watts of 24vdc power to the Bluetti to keep is topped off while pulling 16.8 amps from the 12v battery. I used it like this for several months without a problem and can attest that it works great; just make sure your wiring from the battery to the 12-24v booster is of sufficient gauge.I recently upgraded the battery pack to 24v so I just bought the 24v-to-48v version of this product so I can charge the Bluetti at a full 700 watts at 48v from a 24v source. Since the unit is rated at 960w (20a), I do not expect any problems at all. I'll add the review on that product once I have it for a few months.Highly recommend!

To reduce from 44 to 58.4 volts to 24V

Works perfect! I was a little worried about doing it since I didnt see anyone with the set up I was trying to achieve in my RV. But basically I installed 12kw of lithium’s in my 5th wheel but its all 48v so I still had to keep the old flooded lead acid batteries for all the lights, slides, jacks, etc. I took 4 of these and wired them into my 48v lithium and then on the other end wired it right into the same wire the old 12v batteries were. Gives me 120 amps of power so all of the jacks work flawlessly and the lights are steady. Most importantly it saved me a ton of space and weight, these things are tiny and I just made a piece of wood to mount them on up and out of the way.
