LiPo Watcher is released

Introducing LiPo Watcher!

Not everyone has a current/capacity-sensor in their models so they are forced to monitor the voltage. Wouldn't it be cool and easy to get a simple and understandable "remaining battery-charge as percent"? Here it is!

LiPo-Watchers monitors your main battery voltage and calculates remaining battery-percentage from that.

Nice and very good, and it would be nice to get another colour, when it goes under 30%,
Because of killing the cells.

There's a few reason I rarely use colors, first you get the alarm spoken to you, secondly 14/16 does not have colors (Same app goes to all transmitters). Little bit like "Less is more" :)

After releasing LiPo Watcher I got quickly several questions to make it support LiFe and/or Li-Ion too. 

Already wrote the code for this, and it works:



But there's a catch here, I need Your help!

I need to know the voltage-to-percentage relation for LiFe and Li-Ion. If you have any idea what it is please download a table-file from my server HERE , it's comma-separated csv-file so it opens in pretty much every spreadsheet-application. (Please save it as .csv too after editing!)

Basically I need to know what voltage in LiFe or Li-Ion is what percentage. And yes, all 100 of them :)

Thankful for any help here!

Hi Tero,
with LiFe there might be a Problem.
LiFe did not have a direct relationship between voltage and the resulting capacity.

LiFe,

and also I use a pack with 8x15Ah , when you take 80 or more Ampere from it , the voltage goes under 2,5 Volt per cell and they are full and ok and then it goes up again to 3.3 Volt.
And then when you them use it with only 50 Ampere they Show a voltage from 3,3 Volt over the same time.
