Hi all, I am working on a DIY busking amp (thread here), and have settled on the following specs:
18cm x 26cm x 30cm wooden cabinet
B&C 6XT13 speaker
TPA3116 amp (starting with TDA2050 until I get the TPA3116)
I would like to be able to play the violin outside for a crowd of 20 people in a city center for two hours.
Which batteries should I use? I was thinking of using an 18 5Ah drill battery...but...
Then I thought of making my own 14.8V battery pack with a BMS and four 18650 cells inside the amp, and using a power supply (like a laptop power supply) to charge them.
Would four 18650's (with the protective chips) be enough for my use case ?
Is it safe enough to charge them with a charger?
Any advice much appreciated ! Thanks.

Hi @JMFahey , thanks, I wasn't sure if I should continue the battery questions in the other thread or ask them in this power supply forum; all my questions from now on will be about the power supply.. @Moderation Team please remove this thread if you think it makes sense to do so. Thanks.
