Patrick also tried another battery pack as follows, perhaps pay someone in UK to build that for you?

Thanks CTU

An update on where I got to with battery packs. The board mentioned made by Ian Canada was not practical for running NUCs at 12-19v as it only lasted a short time due to the current demand. BUT the SQ was amazing!

 

So this drove me to research battery packs and I ended up making my own with 8x A123 li-po batteries. This configuration is called a 4S2P - 4 in series 2 in parallel, giving 13.2 volt out, enough to power an NUC. Current depends on accumulated value of batteries in this case 4.2amps.

 

You can buy battery packs ready made online and there is lots of info available for DIY also which I did.

 

Example of a ready made pack (you would need to buy their recommended charger as well).

It's important that the battery pack has a BMS for protection  and charging (battery management system board) This protects against overcharging or undercharging and keeps batteries within a set input and output zone. This ensures the batteries will last as they do not like over or under charging or depletion. This is my pack which I topped/charged up each night with a standard laptop charger and runs an NUC amazingly well with really great SQ.
