12v 10a | battery pack | DIY | TUTORIAL | 18650 cells

This is 12 V 10 A ! At the end of my video I said 12 V 30 amp’s which is incorrect! for some reason I was thinking parallel Connection Which would then be 4.2v at 30amps -had my amps switched around-
( 3 )4.2v In Parallel remains at 4.2v  but doubles your amps. So you have 4.2v 10amps 👈
( 3 )4.2v Paired In Series Is 12.6v your amps remain at 10a

Just FYI Lithium Ion batteries don't like sustained high temps so soldering really degrades them. If you can invest or make a spot welder its much faster and cleaner and most important it wont damage the battery.

These cell holders from the Birds make the best little pack cell holders for other projects or just keeping them organized if you don't have plastic cases for them. The Bird 2/3 battery design is actually pretty slick

[ShouJangers]

how can you recharge it? Because its each cerll or series is to be charged by 5v?

[Reharmonizer]

Don't you need BMS for these batteries?

Not my chair, not my problem! That's what I always say.

One does not simply connect batteries. First to edit your failure you must, as long we don't know if it's 10 or 30, so we guess, we can't trust.
