I don't think it's drawing over 10A, since I have a 10A fuse after the BMS :) But I get your points, I think the boost converter has like 90% efficiency, so that means that 10% more load on the battery, plus the extra load from the amp running on 24V, plus the fact that at a higher amperage, the...

Hello guys, So I have a 5S2P pack I made for a bluetooth speaker (uses TPA3166D2 amp), protected with a BMS board with balancing. I first used the pack directly to connect to the amplifier, and it worked fine, and the battery life was really good, since pack starts at 21V and then goes down to...

Hey, sorry for not having an answer to your question, but what "kit" did you use for that pack?Or how exactly did you build it? One note that comes to mind, did you check the app settings that everything is ok there and it is not something configured incorectly?

Hello again, just realized that even though you guys gave me good ideas, I didn't actually get an answer regarding the main question, what happens when using USB power banks in parallel? If using 2 powerbanks, each with a USB 2A port at 5V, will I get 4A?Or how those it exactly work?Is it like...

Thanks for you suggestions, unfortunately I already order 10 Samsung cells, which should arrive in 1-2 weeks. I wanted to hold an outside party using this pack, calculated I would get like 5 hours of play time at 25% volume, and I wanted to extend that, that's why I was thinking of charging...

Hello, I am new to this whole battery world :) I am building a 5S2P battery pack for TPA3116D2 amp. I have a CC CV Step-Up board to charge it and a BMS. The amp will be directly connected to the BMS. I want to increase the capacity (and run time) of the amp. I was thinking of connected a USB...
