48V to 48V DC to DC Charger
(available now)
offers safe charging between seperate banks of 48V batteries.
BB484830 - 48V to 48V DC DC charger ~1600W. 30A. ideal for charging between 2 sets of 48V batteries. Lithium or lead acid.
Combining a 48V battery bank directly onto an independent 48V battery bank can be perilous due to differential voltages between banks.
A worst case scenario may be a 15S 48.0V lithium battery that is flat ~40V, being connected to a full 16S 51.2V lithium battery sat at 54V. This would result in vast current flows leading to BMS open circuit, meaning no charging would take place. A similar event may occur when simply connecting a full 51.2V battery onto an empty one.
The BB484830 offers current limiting and correct charging voltages for charging between an array of voltages 39V-60VDC.
An example may be that you have a large 48V rack style storage battery that you use to charge up smaller capacity 48V batteries that are utilised in vehicles / electric boats / robots.
The BB484830 can be activated by any voltage signal between 8-80V on the ignition feed. There is also a selectable vibration sensor mode that shall engage the unit when the BB is in motion.

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!!!!

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 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.
