Need someone battery knowledge

Mon Aug 08, 2016 1:30 pm

So I am making a portable big case pi. I don't want a touchscreen I want to buy a 10 inch tft screen. Everything powered by a rechargeable battery.

I really need to know if I have everything correct.

It is not possible to confirm with the information provided, assuming you plan to connect the TFT interface board directly to the battery. I say this because the TFT interface board doesn't give a input voltage tolerance, it simply states 12V@1000mA input. The battery output voltage range is 10.8V - 12.6V, will the display work over this voltage range?

I will also say that the battery manufacturer, or seller, does not understand the basic CE marking requirements as I fail to see the manufacturers brand name/address on either the battery charger or battery label. Li-ion batteries can be particularly dangerous if not designed and used correctly so when I see cheap, incorrectly labelled products like this I normally look elsewhere.
