LiPo cell in any kind of extreme situation with heat, water, fire, etc. Now, this cell
used in the NuEVI is small (1500mAh, 3.7V), and it has protection against over
voltage, short circuit and under voltage, and we are charging it with a relatively
small current (<430mA), so normal use should be all safe. And of course, the
LiPo cell should be recycled in a proper way if for any reason replaced or
retired, not ever just thrown in the bin.
With the LiPo battery solution installed, the NuEVI or NuRAD has three
positions on the power slide switch instead of two.
The switch positions are:
[ • ] [ ] [ ]
Leftmost position – Power ON from battery, battery time 20+ hrs
[ ] [ • ] [ ]
Mid position – Power OFF, battery charge when USB is connected to a USB
power adapter (500mA or higher) Charges to 80% in 3.5hrs, 100% in 5.5–6 hrs.
The red LED in the battery compartment is lit until the battery is fully charged.
[ ] [ ] [ • ]
Rightmost position – Battery power off, power ON from USB if connected
(no charging, low power consumption)
For models with AAA or AA battery holder, the power switch has two
positions: Left for battery power and right for USB power if connected.
