It is a little bit tricky. you just use the small battery as a BOOSTER. may be other kind battery can do the same.

no.. it’s not a booster.. The Oem car battery is 11 years old and is pretty dead. it is more like a load than a battery.. so the pack i built is also putting some current to the dead battery and to the starter. I also tried to discunnect the OEM 12V battery ad the little pack work better WITHOUT the car 12V battery.

that totally works ,, any 12volt battery will start a car
I once used a 12volt mikita cordless drill battery
and item your using puts out 12volts in DC form

It’s really not ANY 12V battery that can start a car. (BTW All battery are DC…)

It depend on the current capability of that battery.. Power is Voltage time current.. and to start a gas engine you need BOTH.

These cels can produce easy 120A during 10 second and near double during 2-3 sec… not a Makita cordless drill battery!.. The Makita LIthium are using the Sony Lithium manganese 18650V and VT) and they are capable of 30 or 40A max for the bigger pack ( BL1830)

What if I used these cells to repack my laptop battery? My stock 6-cell battery is crapping out, and it would be nice to have three of these in my laptop.

Would it work as a direct replacement to 3.7V Li-Ion cells? I’m aware of the lesser voltage…

I think You are asking a bit much from those ANR26650M1 cells, what your doing in this vid are what manufacturers call “ABUSE”.
If your car did not start immediatly than you would begin to exceed the batteries capabilities very quickly causing overheating of the cell and gaseous venting.
I run a 13.2v 9.2ah for my starter, which places the 250A load at 27C which is within the manufacturers specification.
