I have 2 of these packs that I bought for a project and decided to change directions and do something different. I hooked them up to test my build and then changed my mind. They are new, only had a couple weeks and hooked up once for 10 minutes max, still have initial charge on them. I only want to sell them together, I will include the series Y-connector if you would like. $75 for both plus shipping, lower 48 only or local pickup in NE Kansas
