Optimised for stringed use in large sized solar installations, Rolls OPzV Gel range is designed to maximise efficiency and cycle life, making them ideal for off-grid solar applications.

Ready-made cables for connecting batteries in series or parallel. Cables include two crimped terminal lugs.

A handy device for quickly checking the level of your Rolls Batteries. Simply unscrew your regular cap and screw this one in, repeat for each cell in your battery system.

Rolls Batteries AGM Terminal Covers to help prevent the possibility of short circuiting the batteries by insulating the terminal.

The Rolls AGM S Series battery range provide the performance and life of a true deep cycle battery with all the convenience of sealed construction and being maintenance free. They feature thick plates with a high density active material. This design allows for reserve energy to be stored deep within the battery plates and released during slow discharge. The Rolls AGM range are sealed, non hazardous, non spillable and completely maintenance free. They can be operated upright on their sides and are leak proof, shock and vibration resistant.

The Rolls AGM R Series batteries are an economy alternative to the red series 5. These batteries are deep cyle, sealed and maintenance free, perfect for smaller renewable energy projects.

Terminal covers protect against accidental contact & possible short circuit.

These heavy duty batteries are designed for unsurpassed repeated deep cycling service in renewable energy applications. Thick plate design with high density active material and increased liquid reserve. Several 2V cells are pre-assembled together to give higher voltage blocks. These in turn are connected to form a battery bank with appropriate voltage and capacity. Unique battery design features dual container construction. Removable cells are fitted with a durable case giving double protection against breakage or leakage. Easy on-site assembly with no special tools or skills requires. Supplied fully charged with inter-connectors. Self Discharge: ~2-3% per month.
