The Energy Bull Capacity Calculator

Which is the most suitable battery? This question is often asked when an optimum power supply is being sought for a certain piece of equipment. In such situations, the Banner Capacity Calculator is just what’s needed, as in only three steps one can quickly and easily determine the power needed for a particular application and hence the suitable battery type.

STEP 1
Establish the power need for the desired application, or device, etc. in watts (from various technical descriptions, instructions, ...).

STEP 2
Consider and define the period of time that use of the device/application will involve before possible recharging.

STEP 3
Once this information has been gathered, use the Banner Capacity Calculator on www.bannerbatteries.com, by entering the values directly online. The energy requirement and the ideal type of Banner Energy Bull will then be determined automatically.

Your in-board capacity requirement is too high for one battery.
For your in-board network, you require several batteries with parallel connection.
The capacity of the batteries then accumulates.
Warning! When charging, spread the voltage in line with the internal resistance of the batteries!

Your in-board voltage requirement is too high for one battery.
For your in-board network, you require two batteries with serial connection.
The voltage of the batteries then accumulates.
Warning! When charging, spread the voltage in line with the charge status of the batteries!

STEP 4
How to calculate the required Energy Bull capacity. An example.
A battery is required for an electrically powered boat. A 600W e-motor is used with a 24V electrical system. In addition, a radio, various navigation lights and a depth sounder have to be supplied with power (total 50W). Five hours of autonomous operation are required.

These values are now used in the following equation:

Watt : Volt = Ampere x Hours x Safety Factor = Battery Capacity in Ah

i.e. 650 : 24 = 27 x 5 x 1,7 = 230Ah (K20)

As a rule, the safety factor should amount to 70%. In the case above, two Energy Bull 968 01 batteries (230Ah each) used in sequence would be advisable.
