If this helps, please give me a boost, thank you!!!
Required materials: Lithium battery (maximum dimensions 35*20*7 mm), 3.7V to 9V step-up charge-discharge module, 9V battery snap T-type.
My lithium battery and battery snap were spare parts, essentially free after using a coupon on Taobao.
Assembly requires soldering with a soldering iron, exercise caution!
Note the polarity of the 9V battery snap; the one in the image is salvaged from a faulty line tester, disregard wire color and solder according to the polarity markings on the snap.
Prevent solder from flowing onto the back of the module; after securing the cover, use tape for reinforcement.
