Risk of fire with PiPower

The Pipower UPS uses Li-ion batteries. There seems to be a real risk of these types of batteries -used in eBikes etc- catching fire (spontaneously, or during charging, or…) Is there a risk of these batteries in the UPS to catch fire?

I apologize for getting back to you so late.
Not really, we have tested it for a long time.
We suggest you use the official Raspberry Pi power adapter to charge, or a better 5V 3A power supply to charge.
Pay attention to protect the pins of PiPower, avoid contact with metal, resulting in a short circuit can be.
