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.

The Bord has two LED, a blue one and a red one. I like to know what it mean when only the red one is active and what it mean when the red and the blue are active.

Idon't think the price is high for such a genuinely working board. I think it is fair priced. Any other board with much lower price translates in lower quality and reliability. Prove me wrong.
