Husqvarna, your batteries are too expensive and underrated for their purpose!
I have 5x BLi200X batteries over the years and many have less than 30 cycles over their 3-5yr life - Some are just showing full capacity and dying after 5min, some are only charging to 3/4 bars. I thought I might check their construction but it's all potted. Time for a new one without the $$$ I started with a top and bottom cell holder with heat inserts. I will print the rest of the shell in ABS-GF later and slightly modify the mower casing so it will fit. This was just a proof of concept but appears to be working well so far. The cells are TB-33138-HE that were kindly donated from a friend out of a power station which failed - So 12S, 2P 29AHr LiFePO4 battery with a 60A JBD BMS.
