Learn MoreFigure 1. Typical discharge curve and polarization. (1) Ohmic polarization: caused by the resistance of each part of the battery, the pressure drop value follows ohm''s law, the current decreases, the …
Learn MoreFor example, a battery with a maximum discharge current of 10 amps can provide twice as much power as a battery with a maximum discharge current of 5 amps. This number is important for two reasons. First, if you …
Learn MoreThe maximum continuous discharge current is the highest amperage your lithium battery should be operated at perpetually. This may be a new term that''s not part of your battery vocabulary because it is rarely if ever, mentioned with lead-acid batteries. RELiON batteries are lithium iron phosphate, or LiFePO4, chemistry which is …
Learn MoreThe problem is how to determine where the point of 0% SOC is, since the discharge voltage is lower than the resting and charging voltages. You can discharge to a set voltage and take that as the 0% SOC point, but if the discharge current or temperature changes then the 0% voltage may also change.
