"Here are 12v 10ah BMW packs that use 6 Lithium Titanate cells in series. You know the new vehicles that turn off and restart every time you come to a stop? Well these are the batteries."
12 volt, 10AH, 130 amp busbar wiring but capable of 500 amp pulses (maybe 30 seconds). LTO cells stay charged for a LONG time in storage and this can probably start any vehicle in decent shape - but not that 40-year-old diesel tractor that hasn't been started in 15 years ;-) Lots more power delivered than the jump start packs with a 12 volt, 12AH AGM battery where the best use is to let the vehicle battery charge for a minute and then see if it can crank the engine.
You would need to replace the BMS with a proper one as the original is proprietary (only talks to BMW vehicles or a BMW test unit).
If you want power for outside lights or chicken coop doors/windows or power gates, these are rated for 20,000 charge/discharge cycles (that's one cycle per day for 54 years and 9 months) which makes them a lifetime battery in almost any type of service.
