External Battery Terminals

[captain55]

I have a 24' Pantera with the battery and the Lenco electric hatch opener under the sunpad. I am still worried that the battery will drain and I will not be able to easily open the hatch to get to the battery. I have seen external battery terminals that can be mounted with cabin access under the back seat. Who makes these terminals? Is it a good idea? Captain55

Dana marine makes a nice setup with a cover and everything.

The battery on/off switch is also under the hatch but the power to the Lenco jack is always on. I always turn the battery switch to off. I guess wiring the Dana part is easy positive to positive & negative to negative. True or false?
