Custom Batteries

Things to consider when choosing cells :

Shape:

Flat contacts or Raised contacts ( Positive end is higher )

Nominal Capacity:

minimum capacity measured in mAh (Milliamp hours) , larger value means its able to support bigger consumption or simply last longer before becoming depleted .

Continuous Discharge Rating:

maximum safe continuous current drain from battery without any ill effects.

Pulse Discharge Rating:

maximum safe short current drain pulse value.

Nominal Voltage:

The average voltage a cell outputs when charged.

Protected:

Integrated electronic protection circuit , overcharge , over discharge , short circuit , over current , temperature etc..
