Lee, you are applying you many years of battery experience from other chemistries mistakenly to LiFePO4. Remember the old mercury cells? Or do the test yourself.

I agree; but that’s irrelevant to the current discussion. If you don’t want to take my word for the facts, and absolutely must see the data yourself, do the search lam the EVDL archives and find the thread on the subject.
The battery was at zero volts for about two weeks. It would also be the basis for further tests. Very alk increase in internal resistance over the bulk of the discharge. Delivery times may vary, especially during peak periods. This item will be sent through the Global Shipping Programme and includes international tracking. 122v7 everywhere only in this topic. This type of BMS just runs one cell totally dead with its own supply current.
I remember it well, but a brief search of the archives did not turn it up.
However, the Linear Technology LTC may be powered separately, or you can place a switch between the battery voltage and the IC’s power 12c7 pin, which can be opened when the battery is not in use or empty. It only charges to Just any design that uses power from a series string of cells to power the BMS.
I know that ASystems did extensive internal testing unpublished on this effect and was on the verge of patenting the “discharge to zero” process, but then found out that this was already in the public domain. Is it a marketing claim, or is there test data on it? Where is the data? That is the point of my question. But I haven’t seen the data. Bill, don’t give me marketing; give me facts.
Essentially storytelling; you know what I mean! To exit the OVP state, apply a load to discharge to the battery. Skip to main content. They are seriously damaged and even destroyed by the experience! Delivery time is estimated using our alk method which is based on the buyer’s proximity to the item location, the delivery service selected, the seller’s delivery history and other factors.
See Shelf Life page Table 15 shows Recommended Float and Maximum Charge voltages. Glove box light left on. I believe that in your case ALM 12V7 batteries it is situation 1. No accessories on other than the engine.

There is a significant difference depending on how cells are discharged: I know you believe it, based on data you have seen. The other 4 cells the control group was left sitting with no load or charging after the discharge test.
I don’t have much luck getting hold of engineers at A
