What does sdh mean for solar base station lithium-ion battery
For example, if you have a 100 amp-hour batteryand use only 20 amp-hours you have discharged your battery by 20%, which means your depth of discharge. . Most lead-acid batteries experience significantly reduced cycle life if they are discharged below 50% DOD. LiFePO4 batteriescan be continually discharged to. . Another great thing about LiFePO4 batteries is that the rate of discharge has virtually no effect on the delivered capacity. This is also not the case with lead-acid.
