This is where I got my battery for a CA Crane Stock. Don't mind the simple looking design of the website, they're amazing. Custom any cells into almost all configurations and their customer service is incredible. Very quick replies to questions regarding dimensions and their custom page allows you to select various models of AEGs to compare what some people have used before. Might be a taaad price, ie $10-30 more but it's worth it for a well made custom pack.
