That yellow connector is an XT 60amp. Miniware stuff is popular among RC enthusiasts, and those XT connectors are typical for (modern) lipo battery leads. I use them instead of older connectors like the Anderson power pole or deans. If I hadn't already bought a dc load when I got into building quadcopters, I would have got this one. It's nice and compact and conveniently has that connector that works on all my lipos smaller than 10Ah. Miniware also makes a great field soldering iron called the ts100 that connects to lipo packs using that same connector. The TS100 is the gold standard iron among RC enthusiasts.
As @KGBot pointed out, it's a XT30. and @christophfuchs407 is correct, it's a remote voltage sense connection. This is used so it can compensate for the voltage drop across the wiring to the unit (if you're running longer wires) it appears that it's optional though as I haven't seen anyone use that connection yet in the few videos I have seen of it.
Miniware tend to have more hits than misses with their products. They have a great line of portable/compact soldering irons as well. Wonder what mosfets they specced out for it? It's not the easiest thing in the world finding linear mosfets around.
Need a noise test in an electric circuit during operation. As well as the reaction rate to changes in voltage when operating in the current (power) constant mode.
what a cute little device. A kind of swiss army knife. If it's 'modulateable' make a great dynamic load for psu stability /phasemargin checking and all that. The RF looks interesting whatever that is. Be great if can wirelessly controlled/monitored. Could integrate these into ATE rigs. Though a USB wired for that prefiere
It certainly is cute. But when that rechargeable battery EOLs you'll end up buying that device again and that one will end up in a landfill. Do you really need a portable device in a lab/workshop? If it were a tiny bit bigger, it would have room for a power jack and could run on a wall wart. It'd be useful for battery testing in the field, I suppose, if you do that sort of thing outside the lab.
In the same price range, the CBA only does 10W. To get higher wattage, it is more money and much larger. Then, from what I see of the CBA, you need to connect them to a computer and run software. While there is some overlap, that's a completely different device.
Bluetooth comms with optional MDP-M01 Smart Digital monitor. See this video titled: Tutorial MDP-L1060 Electronic Load from Miniware by Alejandro Alonso. Would give a link but likely get tagged as spam comment.
Plan to DIY my Load with strip line resistors and copper spreader combined copper pure water chamber. Plan to plumb it to a dc powered fan cooling a tiny air/h20 exchanger. A dc pump maybe be in order aswell as a bigger reservoir depending on wattage & time under load ☺️
