Hand made 3x 18650 battery pack charged but voltage says 3.87v
I resurrected 6x 18650 batteries from a laptop battery , there is nickel connecting the batteries and where a + and - connection should be I soldered on copper wire. Each battery is charged. One is at 3.82v and the other 2 are at 4.2v. I am using them to mod my nerf rival gun which needs a minimal of 9v to turn on , 10v to fire. Anyways, when I connected the terminals together the power sounded way too low. So when I checked the batteries it only read 3.82v . I checked each battery and terminal but they are all fine. Right now I don’t have much money and I cant buy a new power supply for my gun. What do I do? I’ll add a picture if the power pack in about 7-9 hours.
Es esta una buena pregunta?

So is there any way to go without the boards?

I can’t sacrifice much money , but I can sacrifice $1-3 if necessary. But is there a way I can create my own, I don’t have boards but a have a lot of spare parts

Don't skimp. Lithium isn't forgiving when it blows up or one cell discharges and the other cells overcharge. They have a BMS for a reason.
