If a lithium battery has continuous current limits of less than 1x its rated capacity in amp-hours it is because the BMS does not have enough mosfets; its heat sink design is too small to dissipate the heat generated by the mosfets at extended high continuous charge or discharge currents, or both not enough mosfets or heat dissipation capability.
LiFePO4 stands for Lithium (Li) Iron (Fe) Phosphate (PO4), or LFP battery, and is the safest type of lithium battery. Because they don''t overheat, they won''t catch fire even if punctured. And the positive electrode material in LiFePO4 battery is harmless, so it will not cause negative harm to health or the environment.
