5. Notes on Battery Usage
The
E vo
S UPPLY includes a Lithium-Ion battery. It’s a high performance battery with high
power density and low internal resistance, capable of very high surge currents and very
clean supply. The battery has a built-in protection circuit that protects it from overcurrent
and short circuits, overcharge and excessive depletion. The protection circuit should be
sufficient to protect the battery against wrong operation or usage. Moreover, the
E vo
S UPPLY circuit also includes a depletion protection circuit which engages at a voltage
slightly higher than the low voltage threshold as set in the built-in protection circuit. This
allows for battery’s long life.
Despite the aforementioned protection circuits, a Li-Ion battery is a delicate device which
needs to be properly used to avoid damages. Particularly, do not expose the
E vo
S UPPLY
to excessive heat or cold or fire, nor drop liquids on it. Do not short-circuit the outputs.
Should the
E vo
S UPPLY be exposed to temperature beyond the allowed range, put the unit
in a normal environment and allow for at least one hour before operating it. Too cold or too
hot a battery would result in an explosion when operated. Please refer to the specifications
section (Page 10) for temperature limits.
