A rerun of this deal:

OOP (Original Original Poster) says: Clearance deal on the Ctek CT5, note this isn't the normal MXS line but seems to be a user simplified version of the MXS ie it doesn't have as many user options but is designed as more of a plug and play option.
Seems to be less availability this time around.
Only for lead acid batteries
