Battery Amp Hours Chart. E is the energy stored in a battery expressed in watt-hours. To better understand battery voltage range and capacity you should try to understand this correlation between voltage and capacity.
Amp-Hours at 5 Amps Discharge Rate. Or 2 amps for 24 hours. Total consumption Amp-hours Per 24-Hr Day SUM 3 Battery Bank Voltage Ah d BATTERY BANK CAPACITY AMP-HOUR.
For instance at C5 a battery might safely provide 268 amp hours.
In an ideal case the battery capacity formula would be. Amp-Hours at 100 mA Discharge rate. V is the voltage of the battery.
