It depends on what we are going to power with it and what kind of dives we plan to make. With heating systems, using the largest battery will be a sensible choice. These systems consume a lot of energy, and even if you don’t fully discharge the battery during the dive, it will run at higher voltages for a longer period of time, resulting in better heating operation. Here we use a battery as large as possible.<\/p>\n
When powering underwater lighting, it all depends on the type and power of the head. The most energy-intensive are lights with a halogen bulb, more energy-efficient are HID lamps, and the least energy is required by those made with LED technology. Of course, a very powerful LED video light, will need more power than a small flashlight even with a halogen bulb.<\/p>\n
Knowing the power of our head, we can estimate the battery capacity needed.<\/p>\n
In simplified terms, we can assume that for every hour of operation of a 10W head with a voltage of 14.4V (4S), we need 0.7Ah of battery capacity. At 11.1V (3S), this will be 0.9Ah per hour.<\/p>\n
That is, for example, having a 30W head, which we want to ensure operation for 3 hours, we will need a battery with a capacity:<\/p>\n
(30W\/10W)*3h*0.7A = 6.3Ah<\/p>\n
So much for theory, in practice we suggest using a battery that is larger by approx. 50%, due to the natural decrease in its capacity during use and the reduction in capacity if you use the battery at low temperatures. The right choice is approx. 10Ah.<\/p>\n
Using a larger battery, of course, is possible, but it will come at the price of a higher price and weight.<\/p>\n
