Image of a BL1815N battery. Board date is 2014, battery serial number starts with 19, appears to have components on the board verso but I'm not yet able to access.

ROM ID: 13 09 04 64 32 03 7E 2F Batt Msg: 41 43 CB 95 1A 68 00 00 C1 C1 40 41 01 E0 02 03 F0 D0 8E BE 5F 58 00 21 E1 02 0E 01 00 F0 01 03

Notes: This battery is dead from an operational perspective, the 'pack voltage' is 0.079. It was left for a number of years and has a total charge count of 15, it is in a locked state. Battery data read at a similar time to my BL1840 with the temp 1 sensor showing '28.81', and sensor 2 '29.09' with no use and an ambient temp of ~14C.

@eroyee was this battery reported as limited by the software? I currently dont clear the data, so if you have read a fully supported battery and then one with limits, the old value remains.

By limited, do you mean 'locked'? As I recall this one reported as locked, but there was no other message, also pretty sure this was the battery I read first (being the least 'valuable' from an operational perspective I figured if I was going to wreck one this'd be it :). Anyway that's useful information, thanks, I'd looked a bit at the Arduino code, but not so much the Python; have been thinking I might do something with a Pico...
