I still am waiting for my new PCB so I can use smd, I should receive it this week.
The size will be about 30mmx18mm and thickness 5mm for the board, without the LED bargraph.
The LED bargraph is the “biggest” part and the thickness will be added on top of it
If the LED bargraph is too big for you, I can sell just the board, and you can use regular smaller LEDs.
Also I can make a 5-levels board, so that you only have to use 5 LEDs.
I just ordered some components, so I think the quantity will be limited to 8.
Yeah… I am not chinese with large quantity of components, and $2 is barely the price of a LED bargraph…
I can reduce the price, but $2 don’t think about it.
The device is smaller, and more readable than just a voltage, that’s the point I stated at the beginning.
I updated the price.
You see there are a lot out there, so it would be better to take one of these very cheap ones because they are in every detail better. Also a modification of one of the Chinese meters would make more sense than build a crappy thing up.
Sorry for opening your eyes but you have to see everything in context…
No I Don’t, but I want to. I just need something more visual so I can see it in application. I’d like to see how it connects and works with a wP2 myself, and maybe it’s integration with a battery carrier. I’m not knocking it, I just want to see more detail pics of its usage and installment. I wouldn’t mind having something that shows me charging status on my SP2 while its running. Mine is just a voltage meter for testing after the fact. Would it be complicated for me to install? Help me out here.
Essentially what you would have to do is dissasemble the charger and then solder two wires onto the positive and negative. Then you have the wires lead out of the charger and mount the board wherever you want to.
I will show you some pics soon.
Before doing that I checked the whole internet to find the right one, none of them was what I was looking for.
The reasons I did this are,
- The device assesses from 3.3v/3.4v to 4.2v, which is the best range to check li-ion batteries, not from 3v to 4.2, etc. (I can configure it to change the range also, or for 2 batteries, etc…)
- It is small enough to be included in battery chargers.
- I can configure it to have 10 levels or 5 levels, which makes it smaller to integrate in battery chargers.
I can implement 1 indicator for each slot in my WP2 II.
Ive never quite understood how that works. I always think it would just be showing the current running into the batteries from the charger when it’s turned on. How does it know. I love this kind of stuff, but I really need step by step visuals to try it myself.
