I got 1 Watchmon 1 to spare. I bought several for my use and development and its time to get rid of one of the first.
Shipping: Anywhere in the world but you pay shipping. Its dead expensive outside Sweden.
4-14 Longmons depending on...
Thought I had a thread but apperantly not so I create this one.
I have digged into and used this Bluetooth/RS232 BMS that works decent. The software is rather crappy but it seem to work as cheap alternativt. Great for smaller 50Ah and less battery banks. The balancing current is like 60mA so...
Okey sorry for the topic :P
Im working on an awesome little box for carry along. This box need to be universal and practical so I reach out to you guys. My plan is to build and do an very very in depth documentation regarding this box.
The work have already started but I need your guys input...
I want to buy a wind turbine. 500-2000w
Yes i know they dont produce much. yes I know they dont produce as much as solar does. Yes I know i dont make money on it.. But they "could" produce some in the night and would be fun to try out.
Should be able to hook onto my current 48V...
As of today (December 13th 2017)the Batrium Wifi protocol is now open for the public.
To make this a bit easier to work with there is a NodeJs application that comes with it. That code is not pretty but it does it work.
Link to the Batrium software...
Quick video where you can see with termal gun how it affect the cells. I would say its negelectable as long as you use proper soldering iron!
Highest point was like 70C fraction of a second after lifting the iron. Spot welding do transfer the energy more locally in smaller area but that still...
ATS or Automatic transfer switch is something you can use to switch between grid an inverter or generator. In most solar systems that have booth inverter and charger like off-grid and hybrid systems already have an ATS built in. But if you want to build your own or just understand some parts of...
This is how I do it. And I also take a look at the Internal resistance in conjunction with the importance of clean ends for some purposes.
Note for soldering you do NOT need to clean them up much at all!
A quick set of videos in the Batrium jungle will be posted here as I explore them :)
First 2 below. Adding the RGB led and introduction to adding trip shunt. The trip shunt will have atleast 1-2 more videos.
How do we know if a cell on Ebay or other is fake? What should we look for?
I tried put this video together that i hope will work for new guys.
If you find that important information is missing just let me know and I will look into it.
I did check out Ebat. I got a couple of cells sent to me earlier and i was impressed. Thats not often i get that.
More info and discharge graphs including links to the cells can be found here:
Battery 1 & 2 2500mAh 18650 battery
Battery 3 & 4...
Raspberry PI Visualization and controller project
This iso is just a collection of good to have tools, to do automatization and visual graphs bundled into a package that will run on a Raspberry PI.
I have put together an ISO image with what i would consider a collection of tools that i think...
I have 1 Victron 702 shunt to spare
I add a USB cable for it as well so you can hook it up to a computer. Its in Sweden so i prefer Swedish or EU based buyers.
Im open for suggestions regarding price but somewhere around 150EUR
When loading attachments it takes roughly 6 seconds before the data is being delivered. Example this:
Takes 6 seconds before i get any data sent but when sent it goes pretty fast.
Seems like it have issues processing? Low CPU or something...
