Two 12V RV battery packages, and the one difference that matters

The CN-Plus Mini 12V 314Ah is a 12V-class, 314Ah LiFePO4 battery with a 200A continuous discharge rating. It comes in two packages that share the same battery; the difference is whether a power box ships with it.

Package comparison
Package	Total price
Battery and charger	$749
Battery, charger and power box	$849

The $100 difference is between these complete packages, not a quote for a box on its own.

Battery and charger: $749

The standard package includes the battery and the matching charger, plus the accessories listed under the standard kit on the product page. See the CN-Plus Mini 12V 314Ah base package.

Battery, charger and power box: $849

The second package adds the power box to the same battery and charger, for a total of $849, or $100 more. The $100 is the difference between these complete packages; it should not be read as a quote for a box on its own. See the power box package.

What both packages share

12V class, 314Ah, LiFePO4, 200A continuous discharge.
Free standard delivery within the contiguous 48 states and Washington, DC. Online delivery excludes Alaska, Hawaii, U.S. territories, international addresses and P.O. Boxes. Applicable taxes are additional.
Live video installation guidance with Bill, by appointment.
PayPal checkout for the package you select.

Choosing between the two

Because the battery is identical, the choice is about the box, not capacity. If you are unsure what the box changes for your setup, ask before ordering. House power and engine starting are different jobs: an RV house battery supports onboard equipment, while engine starting has its own requirements.

Installation does not apply to these packages

The $350 per golf cart on-site installation is for golf cart battery orders within 50 driving miles of the Fort Pierce warehouse. It is not offered with RV packages. RV support is by phone or live video, by appointment.
