I've been searching the whole internet for a week now to find answers.
I found out that i have two options: laptop cells or VRLA(SLA). Both seem nice but i don't know how to charge them.
Apparently i need some special circuits for VRLA to set exact voltage to 13,4, to limit maximum charge, to set minimum discharge and things like that. I'm also looking for an option to be able to use the boombox while charging/battery is plugged in.
What is my best option? There must be a way.
Is it easier to charge laptop battery cells?
I'd be extremely helpful if you could help me with that. Thanks!

Here is a link to the boards user guide. The last page has contact info for the maker.
To get the max power you will need 24 volts. To get long operation time more batteries in parallel for more current.
You may also have a size and weight limit to work with too.
On Amazon they pair it with this supply
