Cool, I like repurposing stuff.
Bloody laptop batteries cost a shit ton too.
One thing to be careful of.
Those look suspiciously like lithium ion cells.
They can be very dangerous and spontaniously ignite
Dell and Sony had troubles with early versions of their battery packs bursting into flames in laptops, often on peoples laps!
They always have a little cicuit board attached to the pack the surprisingly has 1 or more microcontrollers on them specifically to manage the cells in the pack so as to not over OR undercharge them, both are dangerous.
Be carefull with those little buggers, they may be small but they hold a metric shit load of energy.
Charge them to 4.2 volts maximum as youve seen on the 'net, but be careful not to discharge them too low, I THINK its below 3 volts per cell. May have to google that shit.
