I am looking to powerup the T-amp (TA2021) with 12V-14V/5A capable battery pack. anybody tried to power using batteries? what type of batteries are good from audio point of view? any battery management diy kit/PCB available?
12 volt gell type lead acid batteries are pretty good all rounders being cheap and rugged.
A constant voltage charger with a current limit is all that's needed to charge them... it doesn't come much easier 🙂
Do a google search for " Yuasa little red book of batteries"

I have build a small amp with a 12V/7.2Ahr gel/lead battery.
I used a ready made charger because it was wery cheap.
There is a lot of hours of playing in a battery of that size,
and I think that size has the best overall cost.

any link for the intelligent battery charger?
Just when I am looking for a battery/charger solution for my 2020 up pops a thread. Not to hijack the thread, but I need to fit mine in a 50 x 150 mm space. Are RC battery packs/chargers suitable?

What type are they........Ni-Cad's, NiMH, Li-Ion and Li-Po battery types are used to power RC models.
And more recent and modern types that RC enthusiasts use are LiFePO4 and LiFeYPO4 types (not to be confused with li-po which just stands for lithium-polymer and is just another way of packaging standard li-ion batteries) that although being less energy dense than li-ion is superior in every other way having 1000s of cycles (up to 7000 cycles with only 15% degradation), much higher possible charge and discharge rates than any other battery type, completely environmentally safe, and last but not least thermal run-away being completely impossible due to it's very nature.
Would these new LiFeP04 be any good in regard to SoundNovice's original question of offering better performance in audio terms?
And is there a quality battery management diy kit/PCB that anybody would recommend?

The amp is a 2 X 15Watt Class-D Stereo Power Amplifier Kit - TPA3122
2 X 15 Watt 8 Ohm Class D Audio Amplifier DIY Kit - TPA3122 15W Stereo Amp | eBay
The charger is bought by Biltema, a Swedish Compagny with stores in Denmark.
Batterioplader 12 V, 2 A - Biltema
But I think it can be bought under another name other places.
something like this be used?
Belkin Residential Gateway (RG) Battery Backup - REV B | Battery Backup - UPS | Power | Products | Belkin USA Site
it has got automatic battery charging system with indications etc. and uses 12v/7.2Ah SLA battery.
