Hey fellaz,
***The Rundow(Long/Whole Story Below)
Looking for a cheap alternative to a LTC6804 IC that can be connected to an Arduino in order to monitor multiple battery cell voltages.
I've been doing some research into designing a battery cell monitoring device. There are a handful DIY projects out there but most of them are utilizing the LTC6804 ic.
But they are pretty expensive especially for DIY project that may not work or come to fruition. The cheapest I can find them on the normal reputable sites is about $25 but usually about $30. There are some eBay sellers from China selling them for a couple dollars but 1. I'm assuming they are knock-off and 2. I normally don't spend money and wait a couple months to receive my items LOL.
Now with that being said if there are some cheap clones out there that work with data sheets and what not I'm fine with that too.
**********
Long / Whole Story
My end goal is to have a GUI that shows each battery cells voltage in somewhat real time. The only cheap DIY solution I know of is to use an Arduino.
There are a couple of battery Management Systems (bms) that include this functionality but are fairly expensive, and there are a couple of Arduino based DIY BMS systems also but have much more functionality than I need and also require a "slave" pcb for every cell in the battery and then send that information to the "master" controller. I almost ordered everything I needed from JLCPCB but I'm holding off to Sea there is an easier solution to what I'm trying to do.
The last time I was looking around how to create such a monitoring device, I believe I was told there was a couple of ways of achieving this without using a IC at all... I believe someone mentioned that I could connect each cell to an analog input on a Arduino that has the appropriate amount of analog inputs but would have to use resistors or somehow offset each cell's voltage because the way the Arduino would add them together or something similar.
At this moment all I want to achieve is being able to see each of the battery cells voltage represented in a graphical interface. I'm not looking to do anything with the information at this point. Just want to see it.... I sort of understand how to send the information to a graphical dashboard I just need to figure out how to monitor each cell's voltage and get that information into an Arduino or some DIY application...
Below is a image of what I'm trying to achieve...
If anyone has any ideas whatsoever I'm open to suggestions.
Thanks
