External factors cause battery capacity errors. Actual lithium battery capacity will vary slightly due to many factors including usage, number of charges, charge and discharge rate, etc. The 120 Ah lithium battery purchased via Bluetooth shows 130 Ah, mainly due to external factors causing errors. in battery capacity. Some electronic devices use software algorithms to estimate battery capacity, which may also cause a slight difference between the displayed capacity and the actual capacity.
Can be connected externally. According to the query, lithium battery does not need protection plate, but the battery gets damaged very quickly, so it can be connected externally. Lithium iron phosphate is a lithium-ion battery electrode material with the chemical formula LiFePO4. It is mainly used invarious lithium-ion batteries.
