Hi Arcicorsa, I'm interested in your charger but I'm not clear about a couple of things.
You mentioned using 2 of the metal pads on the bottom of the battery. I tested these with a multi meter but couldn't get any voltage reading. Also, what are the other 2 pads for ?
Also, the Spark battery is a 3s lipo. How are you balancing the charge ?
Hello, on pads you measure no voltage. In battery is on the pads MosFet transistor.. Other pads is data link. Yes battery is 3S, but charging and balancing circuit is in the battery. You connect source in CC (1,5A) mode with end voltage 13,05V on pads according to my photo, battery begin charge. Balancing and stop charging drive the battery. |
