There's the “BD” and the “BE”, and now this “BM”. All I can say is the capacity figures that guy in the video gets, even if at 0.25A discharge rate, are rather beefy.
You forget the BF and BL too, lol, it’s really unclear their name, it seems to me that the BE and BL are 7-amp cells, the BF meanwhile gives 4.9 amps it seems to me?
BE - 1. generation of Tesla Model S 85 cells with carbon anode (unconfirmed)
BM - 2. generation of Tesla Model S 85 cells with C-SiO anode (parameters confirmed by direct comparison with Tesla 85 cells (MY2016) and many cycle life tests in my lab)
BD - is BE or BM technlogy based cell without bottom vent (unconfirmed)
BF and BL cells are based on other technology, I think BF and BL both are C-SiO anode succesors produced by Sanyo of an old Panasonic NCR18650B. (unconfirmed)
Only a guess that it is the evolution/modification of the same 2900mAh technology. I have personal experiences only with PF cell which is an old fashion Panasonic low DCIR cell with great cycle life. (PF has lower DCIR than BM and slightly better cycle life, but it is also slightly more expensive USD/kWh). PD seems to me as PF with bottom vent. I heard about PE for the first time from you.
The specifications do not look very good. I do not like 3.7V nominal, 4.2V charge voltage and 2.75V cut-off for 9V batteries, they are specifications for a single cell.
For clarification purposes, Henrik's latest LiFePO4 cell review -Enerpower 18650 3.2V 1800mAh (Blue)- confirmed a well seated suspicion I had with regards to the brand-name OEM behind the 3x wide leg tops: Heter Battery.
Thanks Henrik. I believe there is some market for small LiFePO4 cranking batteries. However, I wonder how much actual lifespan can be expected from a LiFePO4 battery in this regard. I mean, without some sort of adjustment modification to the vehicle (motorbike) voltage regulator.
Recently a friend of mine visited me with an old store bought small bike LiFePO4 battery. We carefully dissected the box with my rotary tool and found a set of 4x prismatic cells inside, they weren't looking very good and some were leaking a bit. A balance board was also inside, but after testing with my power supply unit I found none of the balance stages would activate with less than 3.7+V. In my opinion this is a joke because at that point the battery is more than probably receiving substantial damage. Yes, I am battery care picky.
I kept the box just in case I decide to custom build some battery.
