Batteries and Accessories
Battery is a device consisting of one or more electrochemical cells with external connections provided to power electrical devices such as flashlights, smartphones, electric cars etc.
Polymer Lithium Ion LiPo Battery
These Polymer Lithium batteries come with a built-in protection circuit that protects against; over-voltage, over-current, over-discharge, and also provides short circuit protection. These are very slim, extremely light weight batteries based on Lithium Ion chemistry. Each cell outputs a nominal 3.7V at 1000mAh! Comes terminated with a standard 2-pin JST-PH connector with 2mm spacing. These 3.7V Polymer Lithium-Ion (LiPo) batteries provide a high power capacity in a very small lightweight package. This makes them ideal for many applications. They are often used in portable consumer products such as Bluetooth speakers and mobile phones.
Battery Holder
Battery holder is one or more compartments or chambers for holding a battery. For dry cells, the holder must also make electrical contact with the battery terminals. For wet cells, cables are often connected to the battery terminals, as it found in automobiles or emergency lighting equipment. Proto-Pic have many types battery holder.
