No need for a diagram!
I use a portable battery car jumper like the one below, it has 2 different power plugs, one is RCA, the other is a cigarette lighter socket. I can use either.
I wire that to the power in on the TPA3116DA board. That's it.
If you want a smaller battery, you could use those smaller boxes that also give 12V, although I'm sure they wouldn't run for 3 days like mine, but you might be ok for a full day with one of the small ones.

An externally hosted image should be here but it was not working when we last tested it.

Perceval, because of you I'm building some TABAQs. Which TPA3116D2 amp do you use? I'm reading through all the threads but there is so much information to digest.It is not a dream.
I have a very portable (although not super small) system with a pair of TABAQs, driven by a small TPA3116D2 with no distortion. I use a 12V emergency battery to power the system and it goes for a long time. Last test was 3 days with music from 9am to 11pm and there was still power to go!
I think I've seen that one on eBay. I'm thinking about trying one with Bluetooth because I know my wife would want to stream if she could.

Well, some time after my deception I'm planning to rebuild the project with some new ideas.
First of all the battery, Perceval my intention is to have a portable speaker and your solution is so good but not so portable.
My bid is to use 18650 battery like these ones: https://www.amazon.es/Malloom-5800m...?ie=UTF8&qid=1488546246&sr=8-3&keywords=18650
With 4 of this can give 14.8Vcc and... 23.200mAh!
To increase the bass I've bought 2 passive radiators so close than the bose minisound link uses, like this ones: https://es.aliexpress.com/store/product/New-1-Pair-Bass-Speaker-Plate-Passive-Radiator-Auxiliary-Bass-Rubber-Vibration-Plate-78x41mm/1709397_32793679340.html?spm=2114.04010208.3.10.r16752&ws_ab_test=searchweb0_0,searchweb201602_3_10000560_10000606_10000561_10000073_10000357_10000074_10000608_10000709_10000660_10000704_10000703_10000175_10000507_10000505_10000558_10136_10000068_10000552_10000063_10000365_10000367_10099_10000156_10000663_10000665_10096_10000669_10000569_10000097_10000094_10000337_10000723_10000090_10000147_10000091_10000726_10000144_10000339_10000150_10000679_10084_10000678_10083_10000676_10080_10000153_10082_10000673_10081_10110_10111_10112_10113_10000535_10114_10000534_10000089_10000086_10000710_10000083_10000349_10000690_10000135_10000716_10000080_10000693_10078_10079_10000717_10077_10000688_10073_10000684_10000140_10070_10122_10123_10126_10124_10000546_10065_10068_10000132_10000033_10000030_10000026_10000126_10000023_10000129_10000123_10000696_10060_10062_10000699_10056_10055_10054_10000632_302_301_10059_10000120_10000020_10000013_10000117_10103_10102_10000016_10000114_10000111_10109_10052_10053_10107_10050_10106_10051_10000621_10000384_10000629_10000101_10000100_10000576_10000579_10000104_10000045_10000578_10000375_10000108_10000377_10037_10000612_10000390_10000613_10033_10000042_10000592_10000594_10000039_10000587_10000036_10000389_10000187-10050_10033,searchweb201603_9,afswitch_1,ppcSwitch_2,single_sort_0_default&btsid=b997f52f-a424-468d-b0f4-32dfb64a0caa&algo_expid=98a9c3e9-0ed7-41da-8125-01652f8f1c82-1&algo_pvid=98a9c3e9-0ed7-41da-8125-01652f8f1c82

Do you think it can be possible?
Thanks!

Hi!
Thanks xrk971, I've now the charger and the dc step up, the BT amp is a good idea but can understand why use the LiPo battery instead the 18650 ones... Is any reason that I donw know? The 18650 are 5800mAh each ones and using 4 of them can give more hours of music than the Lipo ones isnt it?
Thanks a lot for your support!

Hello, and thanks for the ideas!
I'm just looking for a new bluetooth amp on aliexpress but no ones fit all my wishes...
Just one TDA7492 with bluetooth can be close to my needs because on some sites people said that have less distortion than the 3116 ones.
Have you know any other board with bluetooth and less than 25$?
thanks a lot!
