SmallBMS for Smart LiFePO4 Batteries with M8

A simple and low-cost alternative to the VE.Bus BMS. The smallBMS can replace the VE.Bus BMS in several applications. It is however not suitable for use with VE.Bus MultiPlus and Quattro inverter/chargers: it has no VE.Bus interface.

The smallBMS is intended for use with Victron Smart LiFePo4 batteries with M8 circular connectors. The smallBMS has three outputs, similar to the VE.Bus BMS. Load Disconnect output The Load output is normally high and becomes free-floating in case of the cell under voltage (default 2,8V/cell, adjustable on the battery between 2,6V and 2,8V per cell). Maximum current: 1A. The Load output is not short-circuit protected.

The Load output can be used to control:

  • A high current relay or contactor.
  • The remote on/off the input of a Battery Protect, inverter or DC-DC converter, or other loads.

Pre-alarm output

The pre-alarm output is normally free-floating and becomes high in case of the imminent cell under voltage (default 3,1V/cell, adjustable on the battery between 2,85V and 3,15V per cell). Maximum current: 1A (not short circuit protected).

The minimum delay between pre-alarm and load disconnect is 30 seconds.

Charge disconnect output

The Charger output is normally high and becomes free-floating in case of imminent cell overvoltage or over-temperature. Maximum current: 10mA. The Charger output is not suitable to power an inductive load such as a relay coil. 

The Charger output can be used to control:

  • The remote on/off of a charger
  • A Cyrix-Li-Charge relay
  • A Cyrix-Li-ct Battery Combiner

System on/off input

The system on/off input controls both outputs. When off, both outputs will be free floating so that loads and chargers are turned off. The System on/off consists of two terminals: Remote L and Remote H. A remote on/off switch or relay contact can be connected between L and H. Alternatively, terminal H can be switched to battery plus, or terminal L can be switched to battery minus.

Protects 12V, 24V and 48V systems

Operating voltage range: 8 to 70V DC.

LED indicators:

  • Load ON (blue): Load output high (cell voltage >2.8V, adjustable on the battery).
  • Temp or OVP (red): Charger output free floating (due to cell over temperature (>50°C), cell under temperature (<5 °C) or cell over voltage).

Perfect
Color: Blue, Size: Square
Just what I needed. The size is perfect as I didn’t want anything too large to place my watches and other accessories inside near the corner of my desk. Its size is essentially 7x7, and the design is sleek compared to other organizer holders. I got the color in blue and it looks stunning with the rest of my setup. I’m unsure about other reviewers, but mine came safely and the leather walls are decently thick, so it’s not too flimsy when buttoned together which holds very securely. There are hole spaces at the bottom corners once assembled, so if you have super small items such as beads or really small jewelry, they could potentially fall out, but most of my items are large enough that won’t be of concern. If you have a wire charger near by, the holes could be used to charge your smartphone inside, which has its own practical usage. Overall, I’d definitely recommend it if you’re on a lookout for a sleek but compact organizer holder, and I personally will consider getting another one in the future for myself for other household belongings.

So immersive, easy to set up and affordable it beats our Phillips Hue set up!
If you want a stunning, immersive viewing experience this set it for you! It can sync with up to 5 Govee light strips or bulbs for and even more immersive experience too! We have 3 different Govee backlight set Ups and this is the best one. It levels up our gaming experience. I cannot imagine watching movies without one now. Theater experiences are lack luster in comparison. Definately watching their how to videos on proper set up and syncing using those funny orange foam pieces! It makes things so much easier! The difference in the color displays are amazing! We synced 3 Govee rbgic light strips and two govee bulbs to the system. We get so many compliments on how incredible the room looks. When combined with relaxation, music or oled videos it's like a sanctuary! It is better in some ways than the Phillips $500 Hue set up we have on another set. It's a good idea to leave some of the adhesive spots on the led strip unused and covered in case your TV dies or you get a new one. This adhesive strip is strong and not reusable. Our new TV died during a power outage. This strip came off fine but lost all it stickiness once removed. Hopefully you won't ever have to remove yours. This is definately a 100 out of ten for us!

Great lights
Gorgeous lighting, it syncs perfectly with the tv colors and when the tv goes dark the lights go off, very cool effect. Happy purchase.

Don’t waste time and money with the off brands buy the real deal.
What a creative way to watch tv, play games or watch movies. The length covers the entire TV, colors are amazing. There is a simple app the makes it so easy to use, change colors add custom designs. The options are unlimited and if you need help create the best experience but not sure what colors they have a community that’s done it, search your favorite sports team and have the colors of your team its so awesome to see. The functionality is endless. app is very easy to navigate, I have had mine installed for over a year now and the adhesive quality is something I never seen before. They have been removed from one Tv to my current one and not a single issue they just stick and don’t come off unless you want them to. I know you can find off brands for a lot less money, but you are not getting these immersive colors and brightness. I have tried multiple others trying to save money, in the end i spent more rebuying and reinstalling. Then still ended up buying the real thing. Do yourself a favor and just buy these instead of the cheap ones, those wont last only half the side of the tv works after a few weeks. The adhesive is either not sticking from the start, or within a week or 2 they will fall off. And they are just not bright, unless you see in person you just can’t get a picture to show the quality and brightness of these lights.

Awesome product!
Ok so I was skeptical at 1st with all the mixed reviews but I finally decided to give it a try. Let me start off by saying this you will have to do some set up in the settings as all tvs are different and to get the best experience it will take some time and patience. After about 30 minutes of moving the towers around and tweaking the settings I finally got it working right. I am very satisfied with it as it makes watching movie so awesome. Some colors don't match up perfectly but as in shades of colors. I definitely recommend this to anyone that wants to take movie nights to the next level.
