Sigh... has someone got it right yet?
We gave up on this years ago on the assumption that no matter how good of a job we did someone would beat us to the punch, under cut us, and we would eat the development costs.
Assuming the average high power ebike battery would look something like:
13S to 24S
10Ah to 20Ah
Discharge Currents from 20A - 80A nominal with bursts upward of 300A
3.0V to 3.6V chemistry
Balance needs in the hundreds of mA or less
Quiescent current that would allow a year + of shelf life
Ability to terminate Charge or Discharge based on programmable limits (Voltage, Current, Time, Temperature)
Thermal inputs - 5 minimum
Ability to detect abnormal starting conditions (like a pack that has been abused)
Very small, IP67, mass produce-able
Ability to stack and accommodate any combination of cells in chunks of 4S or greater - such that any two packs can be hooked in parallel or series to meet requirements
Noise immune
Wireless connectivity via BlueTooth or other for logging, phone apps, etc - or some other method of display and programming other than a USB port
Something like that?
