I want to create a custom battery solution for some flexible LED panels that I bought for video work.
The panels have the following specs:
Those are the “on sheet” specs. I tested the consumption and was actually a little lower with the original PSU.
The requirements for the battery bank I want to make are that each lithium battery needs to be under 100Ah to be able to be taken on a plane, and that I would like to stick to a battery that I can use for something else.
There are V lock and L series batteries that are used commonly for video work but they are costly and their use, other than for the lights, would be limited for me.
I intend to use Milwaukee M12 tool batteries because I already have some and I have Milwaukee tools, so I can utilise the batteries for the tools. They also have internal over discharge protection and the chargers are both quick and condition the cells each time.
I tested a panel with two of these batteries running in series and they are capable to power the panel, but once they start loosing the charge, there is a dimming effect in the intensity of the light. Hence I need a device to regulate the power.
These batteries fully charged hold 12.04V (24.08V in series) and after an hour of running the light they are about 11V (22V in series). They are the 2.0Ah version.
So my question is. If I was to run two of these 12V 6Ah batteries in series, or even 4 of each in a 2 in series, 2 parallel configuration. Which DC-DC solution would you suggest to keep the output constant at 24V-26V?
The 150W DC-DC Boost Converter 10-32V to 12-35V 6A SKU: 018-DCDC-BOOST-150W https://core-electronics.com.au/150w-dc-dc-boost-converter-10-32v-to-12-35v-6a.html
Or the Pololu Adjustable 9-30V Step-Up/Step-Down Voltage Regulator S18V20AHV SKU: POLOLU-2573 https://core-electronics.com.au/pololu-adjustable-9-30v-step-up-step-down-voltage-regulator-s18v20ahv.html
I need to build three battery units to run up to three lights at the same time.
I already added those two converters to my wishlist waiting for you advice and clarification.
