Bought less than a year ago on Amazon. I opened box and looked at it, and stored it with the other components I bought to build my off-grid solar system.  The system ended up being larger than this controller can handle, so I have no use for it.

However, it is a 60A / 160 V DC charge controller, so plenty of capability.

It's never been hooked up, I believe it works perfectly.

Very highly rated on Amazon, and still selling there for $90.00

For Lithium/Vented/Sealed/Gel/NiCd batteries.
