WTT 12s 80a BMS

Hello all, I have 3 of these 12s 80a discharge BMS which I purchased from alien power systems no too long ago. They are brand new. I have decided to change to a 10s battery so I would like to trade someone for 1 or 3 10s 80a discharge BMS. I am in the USA. https://alienpowersystem.com/shop/bms/battery-bms-with-switch-for-12s-lipo-battery/
