Relevant experience and suggestions for using iron-lithium batteries

1) When the lithium iron phosphate battery is fully charged, do not rush to unplug the charger. You must allow sufficient time for the battery pack to automatically balance and let each group overflow. Otherwise, the voltage of individual battery packs may gradually be lower than that of other groups and affect the normal use of the entire battery pack. 2) If the battery pack capacity drops in a cliff-like manner in a short period of time, in addition to excluding physical external forces (such as part of the battery falling off due to a car crash, etc.), the balance of the battery pack must be considered. Readers who understand this and have a certain degree of practical ability, it is best to disassemble the battery for manual balancing. 3) It is best not to use stainless steel for the battery casing, which will not only increase the cost but also be difficult to disassemble for maintenance. 4) If the battery pack is found to be used abnormally, it must be maintained in time to avoid irreversible damage to the battery pack after a long time. 5) It is recommended that people with a certain electronic foundation use lithium iron phosphate batteries, because the biggest problem with this type of battery is the inconsistent performance between battery packs. In the case of a balanced protection board, it is unlikely that the entire battery pack will be damaged. During maintenance, if the entire battery pack is scrapped due to the degradation of a certain battery pack (or the repair price is slaughtered), it is too cost-effective. 6) It is not recommended to buy lithium iron phosphate battery packs online. Because most of the battery packs purchased online are second-hand battery packs eliminated by electric vehicles, their performance is uneven, and if they don’t know how to maintain them, they will soon be scrapped. For readers with hands-on ability, you can purchase a brand-new battery and assemble it yourself. 7) Do not use the battery pack without a balanced protection board. It is easy to cause overcharge and overdischarge of some battery packs, or the performance of individual battery packs becomes worse and worse, which shortens the service life of the battery pack. 8) The maintenance must be carried out strictly in accordance with the operating rules, and no short-circuit is allowed. Due to the small internal resistance of the battery, a short circuit will cause it to smoke and damage it instantly, and even cause dangerous accidents such as fire and explosion. 9) Because the sequence of removing and installing the equalizing protection board is not correct, it is easy to damage it, so do not disassemble the equalizing protection board easily during maintenance.
