Re: Is my battery dying ?

DBMandrake, thank you for posting those images and analyses, and thanks for stress-testing your battery in the interest of science. My impression is that your battery is just fine and does not exhibit the dramatic individual cell failure which some of us have experienced (and which was cause for ba...

Re: Canion

I've posted in this thread over in the scantool forum, should be interesting! :twisted: https://www.scantool.net/forum/index.php?topic=14605.msg52688#msg52688 The post I'm replying to (responding to someone else with the same problem) seems to be trying to say that the automatic reconnection that Ca...

Re: Is my battery dying ?

I dont disagree with the data, but seems unlikely that two cells would weaken at the same time... though I do understand your concerns. I would want to do the cell balancing procedure and repeat this test a couple more times and keep an eye on those two cells. What "cell balancing procedure&qu...

I read that thread but I'm not sure what part of it you're drawing my attention to or how it relates to my problem ?

Re: Canion

I've had a chance to drive home and do some testing with the latest 4.3.0 firmware on the OBDLink LX but unfortunately it doesn't solve the problems and in fact seems to introduce one new problem! :( The new problem is that with the original firmware (version unknown as the OBDLink app reported it a...

Re: Is my battery dying ?

From what little data we can find on the cells, 4.2 V is 100% and they consider drained to 0% at 2.75 V when making cell meaurements at Yuasa. That's what I've thought for a long time as well but I happened on this technical article from Yuasa just today that seems to imply that the 50Ah capacity i...

Re: Canion

At long last I was able to start using Canion yesterday using an OBDLink LX. Many thanks to Martin and Xavier for such a great program. :D I have a few questions about the use of the app that maybe someone can answer, as well as some bluetooth connection issues. I'm running the app on an Amazon Fire...

Re: Is my battery dying ?

I had a lot of trouble with my OBDLink LX dropping the bluetooth connection by the way - it would work for a random amount of time from a few minutes up to 20 minutes or so before the fps figure would drop to 0 and the adaptor would "lose" pairing to the tablet. (Amazon Fire HD 8) When thi...

Re: Is my battery dying ?

I've managed to record some cell readouts yesterday at 71%, 10% (turtle just appearing) and just this once, I let it drain right down to 0% on the driveway until it actually shut off, to see what the cutoff voltage was. https://drive.google.com/uc?export=download&id=1wgiMoLC33NG03IanHYnSpHp6GUSz...

Re: Is my battery dying ?

My OBDLink LX arrived today so at lunchtime I popped out to the car to plug it in and it worked straight away. :) The 36.1Ah capacity figure appeared straight away, so perhaps the car broadcasts this figure when the key is first turned on as I had Canion already running before turning on the key. (O...
