8.3. Compatibility Note (from customer reviews)

It has been noted that some DALY BMS models, including this series, may have specific compatibility for 24S configurations. While the product description states compatibility with Li-ion, LiFePO4, and LTO, some users have reported that 24S configurations might specifically require LiFePO4 batteries for optimal operation, or that the BMS might be pre-configured for a specific chemistry. Always verify the exact battery chemistry and cell count settings in the BMS software after initial connection, especially for 24S Li-ion setups, to ensure it matches your battery pack. Incorrect settings can lead to improper balancing or protection.
