18650 Battery for Latte Panda Sigma

Hello hello! 

I have a question, probably "typical" for a non-electrician hahaha.

I'm thinking of building a battery for the Latte Panda Sigma. 

I have searched about the 18650 batterys (5 uds of 3'6V 3500mAh 5A in serie, which makes a general battery of 18V and 3500mAh 5A).

As you can see, it has a voltage of 18V and a maximum discharge of 5 amps, which allows it to cope with maximum consumption peaks of 90W (recommended on instructions).

My question is: does this paragraph refer to whether, by connecting the battery through the JST PH2.0-8Pin port, and connecting the original adapter to the latte panda through the DC Jack port, will I be charging my battery?



Thank youuu!!!!!

Best team, latte panda :)
