tihon You can use a battery of any capacity. But the charge current, as follows from the description, is limited to 1A. Accordingly, if you have a large-capacity battery, it will charge for a very long time (for a 3000mAh battery, the charging time will be more than 3 hours, for example). Discharge current - 3A max. If your device consumes more, it will be switched off by onboard protection. If the battery voltage drops to 2.5V, it will also be turned off to protect against deep discharge of battery. The board does not care it is used to charge a mobile liion battery or some other liion battery. It will charge them anyway. Observe polarity, this is important.

tihon i think its a Intel Celeron J3160 cuz it one have 4 cores + 2MB cache + 3 displays + 2.2Ghz boost if described info on this page is correct.

tihon real weight 10-11g! the weight in description is brutto (plastic + solder)!
