Dead Renogy LiFePo 12V Battery with BlueTooth

Posted on by

Once in a while we post slightly off topic findings that we think will be interesting/unique information for readers.  This post is about the very popular Renogy LiFePo battery with built-in Bluetooth.  Even though we don’t provide solutions for these batteries yet, we have recieved enough guestions about them that we got curious about what seems to be the common failure. This specific post shows the guts of a RBT100LF/P12-BT-US version, but there are versions that will have similar components.  These batteries are commonly used in off-grid applications to provide power to DC and AC devices using an inverter.

Failure Mode

The “dead battery” – This is when there is no output voltage, no bluetooth connectivity and the battery will not charge.  We don’t recommend repairing these batteries due to a fire risk, We decided to get into to understand the battery a little better.  Note that we kept a fire extinguisher near and will not put this battery back into rotation even after fixing the failed part.

Getting Into It

Not a lot of help we can provide here.  We cut, heated , cracked at the plastic and finally got the top to come off.  Send us a message if or make a comment if you find a better way to open a battery like this.  We will recommend it here.

Getting the top off is touch

 

 

BMS Failure, Cells or Wiring

In modern LiFePo batteries, you can break it down into three parts, Cells, Wiring and BMS.  Once the top is removed, the basic troubleshooting can start. Before getting started it is interesting to note this is a pretty high-quality battery, Prismatic cells..solid. Epoxy molded to keep things from moving around..solid.  No corrosion or dust since the case is sealed from the elements..not much to complain about.

If you took a good look at the picture above, you will notice that the voltage measurements and the wiring look good.  Since the cell voltages add to 13.2V and we don’t see any loose wiring, the likely culprit of the failed battery is the BMS.  There is a lot of information on the internet explaining what the BMS does, but basically, it makes sure the cells are balanced and it cuts off the connection to the LiFePo cells if there is a fault condition like too cold, cells are under-voltage, charger is trying to overvoltage the cells.  In this case, the BMS seems to be keeping the cells disconnected even though there are no real fault conditions.

What BMS Did They Use?

Well, the big clue are the red heat sinks.  To get to get it the BMS the way we did involved more caveman technics.  A dremel cutting tool is how we did it.

Again, please let us know if you have a better way to get to this.  With some more cutting and prying, we got the BMS out.  Sure enough, it is a standard Daly 4S 50A charge/100A discharge BMS you can get almost anywhere. We will follow up this post will a schematic extraction of the BMS.  Why?  No good reason.  These are so cheap it doesn’t make sense to try and repair it, but we will do it to understand why they are failing.  If you have read this far and actually took apart your battery to find a failed BMS, just buy a new one for about $50.

Not sure how long the link will be active, but this is the one…

Hope geeking out on a LiFePo battery was fun for you.  It was for us, because we love digging deeper.  If you have any questions or general comments please email us at info@comvolt.com.

Jumper Descriptions on Little Giant BL1100 – ZWorld C-Programmable Controller

If you are doing a conversion form Zworlds little giant BL1100, start by understanding what the jumpers are and how they are connected to your application.  Your new design will be dependent on the settings and will likely only need a fraction of the capability of this BL1100 board.  We have seen some applications that use most of its functionality, but it is usually just a couple of IO ports and and communications ports…

Example Code: How to 3D Print Your Own Stand-off’s for Electronics

Posted on by

Often times in electronic assemblies, printed circuit boards (PCB) are spatially separated from one another through the use of stand-offs.  These stand-offs are usually quite prone to breaking, especially if you’re replacing/repairing/generally manipulating the PCBs attached to them.

Finding a stand-off that perfectly matches the original equipment manufacturer (OEM) stand-off can be a real pain, if even possible.  Luckily, with the advent of 3D printers, you can print your own stand-offs to your own specs!

There is an array of software packages available for designing models to be printed by 3D printers.  We like OpenSCAD because it’s:

  • free
  • precise
  • easy-to-use (even with very limited programming experience)
  • PARAMETRIC MODELS

OpenSCAD allows the user to “script” their model to precise dimensions and positioning, as opposed to popular GUI software where the user “draws” the model with the computer mouse.  GUIs are fantastic for artistic models (e.g. miniature sculpture), but not so great for scientific/mechanical/structural objects like stand-offs, where the dimensions of every minor feature to the model make or break its usefulness.

Did we mention that OpenSCAD models are parametric? That means that you can define models according to variables rather than fixed numbers.

For example:  you want a small box to hold your keys.  This box (imperfect cube) only needs to be about 75 mm wide,  25 mm deep, and 50 mm tall (roughly 3 x 1 x 2 inches).  You write some code like  “…cube([75,25,50]);….”  along with some other stuff and that results in a box that’s the best size for holding your keys.

But you really like that box, and you wish you had one just like it, except bigger, to hold your shoes.  So you go write new code  “…cube([300,125,125]);…”.  But then you want another box to hold your silverware.  So you go write more code with those dimensions.

Well how about instead, you have one code file (e.g. box.scad) that begins by declaring some variables:

x = ;  y = ;  z = ;  …and then your line “cube([x,y,z]);”…

Now, you can simply open “box.scad” and change the numbers for x=, y=, z= at the beginning, and the code will automatically generate the box to those dimensions.

Obviously this isn’t the best example – it’s not hard to type “cube([##,##,##]);” multiple times.  But if you’re familiar with OpenSCAD (or any other programming), you know that the code is much more than one simple cube line.  The model you’re generating likely passes x,y,z dimensions into several functions/modules to render the final piece.  It’d be a total pain to hunt down all the functions that use the dimensions you want to change and manually alter them.  So that’s why we define those variables at the beginning and pass them into all our functions.  Then you can simply change the variables at the top of the code anytime you want to reuse it for a slightly different size.

BACK TO THE STAND-OFF

We promised some example code.  So here it is, albeit extremely simple:

r = 5; h = 20; thickness = 2;

difference(){

cylinder(r=r,h=h);

cylinder(r=r-thickness,h=h);

}

 

Simple stand-off generated from the above code in OpenSCAD

Simple stand-off generated from the above code in OpenSCAD

If you download OpenSCAD, you can copy-paste this code right into the editor to make a simple stand-off.  Note that simply changing the numbers for radius, height, and thickness is all that’s needed to scale this stand-off to your liking.

There are a ton of resources out there on the internet to assist you in learning 3D modeling.  But, if you need a specific model and lack the time/will to design it yourself, email info@comvolt.com for any inquiries!
