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

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.
