The Connect-Ease 4 12V Battery Parallel Quick Connect System, MPN RCE412VRV, connects four 12 V batteries in parallel so they work as one larger 12 V bank. Parallel wiring keeps the system at 12 V while adding the capacity of each battery, which extends runtime for RVs, off-grid setups and boondocking away from shore power.
Connect-Ease describes plug-and-play connections and lists the system as compatible with lead-acid, AGM and lithium batteries. Connect-Ease lists 6 gauge marine-grade tinned wire with a 60 to 110 A capability. Connect-Ease states the system handles 60 to 240 A of DC power.
This version does not include the solar splice connection; that is on the RCE312SLR. Connect-Ease does not publish the cable lengths, terminal sizes or fusing in the sources we checked, so measure your battery layout and contact us before ordering.
This listing is for one Connect-Ease RCE412VRV parallel connection system. The shipping options and delivery estimate for your address appear at checkout. Our full terms are on the shipping policy page: https://marinerswarehouse.com/policies/shipping-policy
Before ordering, measure the spacing between your four batteries and check the terminal type. Use batteries of the same type, age and capacity in a parallel bank, add fusing as your installation requires and disconnect all loads and chargers while connecting.
Review the 16 oz gel format, specifications and application directions.
Check fiberglass, gelcoat and finish suitability before use.
Ask about your surface and stain type before ordering.
Review shipping information and return conditions before purchase.
Installation & Compatibility Guides
The RCE412VRV links 4 12 V batteries in parallel. Check these six points before you buy.
This connects four batteries in parallel. It does not include batteries or a charger.
Confirm the connectors suit your battery terminals before installing.
Use only 12 V batteries of the same type and similar age and capacity.
Connect-Ease does not publish cable lengths. Measure your battery spacing and ask us.
Secure batteries and cables so they cannot shift or chafe while traveling.
Add fusing as your installation requires, and disconnect loads while wiring.
A parallel kit links several 12 V batteries into one bank with ready-made connections. Custom cables let you set exact lengths but require crimping and sizing each one, and a single larger battery avoids interconnects altogether.
Compare the RCE312VRV and RCE312SLR for a different battery count or the solar splice. Batteries in a parallel bank should match in type, age and capacity.
