Some time ago, I posted information about a new model of adjustable converter that I had stumbled across completely by chance. But literally that same day, a company representative contacted me on Skype and offered to write a review of the model. I received it not long ago, tested it, and am ready to tell you more about it.

AliExpress is gearing up for a big sale, and I decided to share links to various products I came across. Mostly not because they’re cheaper—we all know how “sales” work—but simply to show you some interesting things.

Sometimes you need batteries with a built-in protection circuit, and the selection of models is considerably smaller. It gets even more limited when you’re looking for models with protection rated for high current. Today I’m reviewing three models, but testing revealed that sometimes things can be so good that they turn out to be “bad.” Still, you can find out all about it in the review.

Last time I covered 26350-size batteries. Today, I'm looking at cells in another uncommon size, 10370. They differ not only in size, but also because they're LiFePO4 batteries.

I never cease to be amazed by the variety of battery sizes, and that's partly why today I'm reviewing some examples of the rather uncommon 26350 size.

As you may know, the RD6006, 6012, and 6018 power supplies support WiFi connectivity when the corresponding module is installed. However, the settings menu and software also include an RS485 option, indicating that this communication interface can be used as well. Not long ago, RD RIDEN added RS485 modules specifically for these power supply models to its store.

RD6018, a new converter from RuiDeng

RD6018, a new converter from RuiDeng
11 8362+6$73.50-77.50
Just under four months ago, I published a review of RuiDeng's new RD6012 converter. Now I have the next model in this lineup in my hands: the RD6018, with an output voltage of up to 60 V and a current of up to 18 A. This review will be relatively short, but I'll still try to make it as informative as possible.

Those who read my battery reviews have probably noticed that almost none of my tests go by without a "conditioning" cycle, which I run using a relatively simple charger. I reviewed it more than 5 years ago, and it served me faithfully all that time. But I think it's time to replace it with something more convenient and powerful, so today I'll be talking about the Vapcell S4 plus charger.

I’ve been a bit under the weather, which is why there haven’t been any new reviews. But I did find time to browse AliExpress, and today I’d like to share some interesting and potentially useful products—or, more precisely, links to them.

For some reason, I rarely review boost converters, and I don't think I've ever reviewed one with this much power. But people often ask me about converters like this, so I bought this one specifically for a review.

Not long ago, one of my readers got in touch and offered to let me test some batteries I hadn't handled before. But in this case, we're not talking about a different chemistry—that part is familiar enough—but about the form factor and capacity. As usual, though, it's best to read the review for all the details.

Not long ago, I published a review of a step-down converter module rated for up to 20 A. As I mentioned then, though, it was already the second one I’d ordered from AliExpress. Today I’m reviewing the one I received about a year ago instead, with my first order.
