Lithium ion battery packs
have a high power storage density and are ideal for application where
weight is an issue. A 18650 lithium cell typically weighs 50gms.
Lithium ion has a low self discharge rate so an unused fully charged
pack will still have full charge after 6 or more months!
The LED strip below powered with one of the Lithium ion batteries below
and placed on top of a cupboard or high point in a room pointing at the
ceiling will almost make you forget that your are suffering
loadshedding.
Why not have a battery and LED strip for key rooms? |
