The latest edition of the TEC-1G pcb has the specific holes drilled as well as a specific battery connection point... But that doesn't mean all the previous versions can't have one. Luckily it uses the top left mounting hole, and two more holes need drilling through the PCB but it is only through the extra copper for the heat sink. So now dodgy re-wiring needed!

It charges using a USB-C port and on a full charge, the TEC-1G can run for a full 6+ hours, with all lights blazing! That's better than your average iPad! :)

In this kit you get the UPS Battery holder, two wire jumpers with JST connectors so you can easily connect and disconnect the battery pack, along with the 3 lots of nylon M3 spacers to secure it all down. Lastly, you will also receive 3 extra nylon spacers for the top right corner of your PCB to keep the whole TEC-1G nicely angled and stable on your desk. The Lithium Batteries can be added as well (I supply 3500mA version), but if you source your own, please ensure to get the "flat top" version that do NOT have the additional protection circuitry in them, as it is not needed (the UPS handles that) and those sort are too tall to fit into the UPS.

Comes with 2 lithium batteries.
