When you charge your battery up with this bms, how are you doing it, just using one of the two battery + - leads? Or did you make a Y cable so that power is going through all four battery leads? Curious what amperage charger your using and how long it takes to charge? I ordered this 10amp one. https://www.amazon.ca/gp/product/B078MYP68W/ref=ppx_yo_dt_b_asin_title_o00_s00?ie=UTF8&psc=1
