Protection Circuit Module (PCB) for 6 cells (19.2V) LiFePO4 Battery Pack at 15A limited (#5453)

The form factor of this PCM-L06S15-C61,along with "may other" coincidences allow me to convert an old Rayovac 6-Volt lantern battery flashlight, with 80 Lumens, into a 4 lbs. flashlight with 14,000 Lumen output, and a 40 min. runtime with 2000+ cycle lifespan. I used a Bridgelux BXRC-50C10K1D7, a large copper heat sink and a COB with 312 LEDs mounted drawing 38.1 Volts at 2.1 Amps. Voltage converted by an Ebay 250 Watt "boost" switcher, de-rated to ~32% of claimed out capacity. My only concerns of the PCM was the relatively low discharge cut-off voltage of 2.0V +/- 0.05V, compared to the newer? PCB-LFP19V15A which a better cut-off of 2.3V +/- 0.1V. I would have attached photos, but that feature is not available.
