Cable Section Calculator

✅ Voltage

Enter the battery voltage, for example, 12.8V

✅ Current

Enter the maximum current that will pass through the cables. Current (A) = Power (W) / Voltage (V)

✅ Length

Enter the cable length, round trip: If your device is 1 meter away, the outgoing distance = 1 meter + return = 1 meter. Thus, a TOTAL of 2 meters of cables.

✅ Voltage drop

Maximum allowable voltage drop = 3%.

Battery Capacity Calculator

✅ Daily Energy Consumption (Wh)

Enter the battery voltage, for example, 12.8V.

✅ Desired Autonomy in Days

Enter the number of days you want to use your battery without any means of recharging.

✅ Battery Discharge Percentage

30 to 50% max for a GEL Lead battery. 80% to 90% for a Lithium battery.

✅ Battery Voltage

Enter your battery voltage: 12V or 24V.
