The Saturn BB4812 DC DC converter and battery to battery charger.

This is a dual purpose device. The first function enables a simple convertion of a 48V (39-60V) DC supply to provide a very stable 12V (customisable) DC Supply to the tune of 40A ~550W. So, it can be used as a standalone converter to give you a 12V feed from your 48V battery bank (lithium or lead acid). This may be required to run 12V fridges, 12V pumps, 12V USB-C laptop / phone chargers, 12V LEDs, 12V ~500W inverter. No 12V battery required, although, there is no problem having one.

It's additional function is one of a DC DC charger. So, just like our range of Saturn BB chargers. It can simply charge up a 12V battery / bank from a 48V supply. It operates like a normal multistage battery charger. This is also 40A rated, current limiting and the charge voltages are adjustable.

Due to its high level of capacitance it operate an extremely stable 12V DC supply. The default, out of of the box 12V output is 13.8V. So, without making any adjustments to the device, applying 39-60VDC to the input, it shall deliver 13.8V at 40A = 552W. Due to its combined charger and converter function a 12V battery doesn't have to be used as a buffer, but of course, it can be added, the BB4812 is current limiting.

I’m happy to give a shout out to VanLife Outfitters. These folks are an incredible example of how a company should conduct business. Although I’m building a truck camper, I have bought several things from VanLife outfitters and their customer service is bar none . I would never hesitate recommending VanLife outfitters to anyone whether they are building a van camper or boat. And I might add even a tiny home. Everyone that I’ve talked to have been nothing but incredible. In particular, Jason in technical support was an incredible blessing to me. I had a problem with the Aqua Hot Gen 1 heater I bought from them. It was not the heater fault, but something I did. Jason helped bird-dog the solution and together we got it fixed. He stuck with me, did research, and called me back several times to make sure that the problem was resolved. These people know the business, many have their on rigs, which gives them the best experience. Thanks you Vanlife Outfitters!!!!

This company is amazing! Quick shipping, best price possible. Customer for LIFE! Thanks Vanlife!

My husband and I are doing our first vanbuild. As rookies, we have found Vanlife Outfitters to be a trusted resource for ease of product shopping and purchasing, video demonstrations, guidance and excellent customer service. They were particularly a great one-stop shop when building our electrical system.

I ordered most of the parts for my sprinter conversion from them. They have absolutely the best customer service. I had issues with my fridge installation duing the weekend and eamiled their customer service for help. Both times, they emailed me back with the instructions/help I need on Sunday. Thank you and this is absolutely my go to place.

Spent lotsa money here, will probably spend more. High quality products, fast shipping and tremendous support. Excellent free resources, e.g. wiring diagrams, on the website. Highly recommend.
