mini box for Lion batteries charger

Small box used to put batt. charger electronics MRB045 for DIY installation of Lion bateries in old appliances working on 12V from ordinary USB charger . Same box can be used for same electronic board with other voltages-depends on number of batteries inside.

Maybe it will be usefull to someone who likes to renew favorite electric tools :-)

*for better work, cooling openings are added in model
