Cllena Waterproof DC/DC 12V to 24V Boost Converter 40A 960W Step Up Voltage Regulator Module Car Power Supply Voltage Transformer (Input 10V-16V)

This is one of the most useful upgrades I've made to my boat. I boat-in remote camp for a week at a time. With long days on the water and not recharging every night, I sometimes end up with a dead starting battery due to livewells, stereo/amp, and other things running. This unit allowed me to rewire nearly all 12v accessories to my 36v trolling motor battery bank so that my starting battery always has power. And it pulls power from across all three batteries for even wear vs connecting accessories directly to individual batteries in the bank. One note: I read some reviews that state the unit was shorted upon arrival due to a significant spark created when attempting to connect the unit. I had the same experience. After emailing Cllena directly (thinking the unit was shorted), I was advised this is common and got some great help from them. I ended up putting a 50 amp switchable breaker in line between from the 36v bank and power input on the converter. Since the switch was off, I had no spark when connecting. I switched it on, and voila! It worked perfectly. So, don't assume a big spark is a sign of a short - it's just a result of 36v vs what some might be used to in 12v systems.

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!

Should you install a 12V solar system or a 24V solar system? If "bigger is better" why not 48V? So we wanted to install several 12V power points since we had a lot of luck with them previously. This device was the easiest way of enabling our 24V solar system to provide 12V. We also have a 12V water pump (although, I've recently discovered the same pump is available in a 24V version <sigh>) Connecting this converter to the "load" on our solar controller made it a simple matter to power the powerpoints and the water pump. The pump maxes out at 10Amps so 120W from this 480W converter should be no problem. OTOH, we have a 240V house (Aussie rules) but the 120V appliances are so much cheaper. We thought about connecting at 3000W inverter to this converter. Oops. I'm sure you see the problem.'' The converter works great. The problem is figuring out what you need it for, :-)

I installed this in my 48V golf cart to run the stereo and rock lights. I also installed a 20 amp switch to the ground side so I could turn the regulator on and off. Well the switch took about 5 cycles before it arc welded the contacts. Tried another switch and same thing. So I up graded to a 35 amp switch and it seems fine now. This thing draws a lot of power when first powered up. But battery draw seems low afterwards, I didn't check current draw to verify. I also have an issue with using the bluetooth on the stereo due to interference from the regulator. They are mounted within a foot of each other so that may be causing the issue.

I use rechargeable electric weed eaters to trim and edge my yard, and a vintage 2009 electric Neuton EM5.1 Mower to keep it cleanly mowed. But the OEM two 12V 10Amp sealed lead acid batteries were woefully inadequate for the task, and I didn't really care for my hacked version with two 12V 21Amp sealed lead acid batteries that I intentionally broke open and flooded with standard battery electrolyte solution, to prevent the cells from drying out, which although a great improvement, weighed 25 pounds for the batteries alone. But when I got my hands on a state-of-the-art LiFePO4 12V 32Ah (384Wh) Rechargeable Battery (batteryspace.com item#26650), weighing only 9 pounds, I made it nest securely into the Neuton EM5.1 mower, and then mounted the Cllena 12VDC to 24VDC Boost Converter 20A 480W Step Up Voltage Regulator Module (see photo). This lawn mower finally works like should, thanks to 2020 technology. The 24V / 32A / 768 Watt 4300 RPM electric motor that direct-drives a sharp, 13.5-inch sharp steel cutting blade (6.75-inch radius) typically draws about 4 - 5 Amps when idle, and about 10 Amps (240 Watts) when mowing, and about 15 Amps (360 Watts) when mowing deep grass. I highly recommend this excellent electronic device.

Worked as expected

Using this to power a 1,200watt Hifonics BRX5016.5. Three years and counting without any problems.

This is an awesome Step-Down Converter. It does the conversion flawlessly with pretty much no loss of power. Please note that the contacts (24IN / GROUND / 12OUT) are pretty close together and require extra vigilance. Note that I also tried the 100A one and it works well

👍

I had a 24v Webasto i needed to run off 12v, worked perfectly.

The device works great. 12v to 24v more than handles the load.

It works very will on the 24 volt espar heater:: that’s in a 12 volt service truck :: witch the heater pull only 4 amps
