UPS HAT For Raspberry Pi offers real-time monitoring
Dec 22, 2021 — by Eric Brown 2,331 viewsSB Components has won KS funding for a $31 and up “UPS HAT For Raspberry Pi” with slots for dual 18650 Li-Ion batteries plus dual 5V micro-USB inputs, 8.4V 2A charging, a 0.91 OLED display, and real-time monitoring.
SB Components, which has launched Raspberry Pi add-ons such as the PiRelay 8, has gone to Kickstarter to fund a UPS HAT For Raspberry Pi. The Uninterruptible Power Supply HAT provides backup power during outages using a battery pack of dual, BYO 18650 Li-Ion batteries. The HAT “allows for the safe, orderly shutdown of a computer and connected equipment,” says SB Components.

The UPS HAT provides dual micro-USB ports with 5V input with a 5V LDO. There is also an 8.4V 2A charging jack. The 94.5 x 56mm HAT communicates with the Raspberry Pi via I2C.
A real-time monitoring chip keeps track of voltage, current, power, and capacity in real time. Other features include a power switch, voltage balancing, a battery protection IC, and a battery reverse indicator.

There is also a $101 bundle that adds a 1.28-inch round LCD HAT and 1.3-inch square LCD HAT that fit over the UPS HAT’s battery pack. The bundle includes a Home Automation HAT and a PiRelay 6 HAT, which is much like the PiRelay 8, but with two fewer relays.

The UPS HAT For Raspberry Pi is available on Kickstarter through Jan. 22 for 23 UK Pounds ($31) through Dec. 25, after which it goes to $41. The Ultimate kit costs $101. Shipments are due in February. More information may be found in SB Components’ Kickstarter page.
Sadly they chose to populate it with scam “9800mAh” batteries, which then colours their product with a “this is a scam” brush.
Yes, any battery over 3000 to 3400 mAh in 18650 form factor is a scam as you point out. Buyer beware!
How about insted the 18650 battery to IMREN 18650 3200mAh 40A battery?
