Qty 2: VMAX XTR6-235 6 Volt 235Ah AGM Battery
VMAX USA’s XTR6-235 pairs two 6-volt AGM deep cycle units to deliver a robust 470Ah combined capacity when used in parallel, or 235Ah per battery for modular setups. Each 6V unit provides an estimated 1.62 kWh of energy with a substantial reserve capacity, making them suitable for RVs, solar arrays, and off-grid cabins. The AGM design offers spill-proof operation, low maintenance, and good performance across cycling and float conditions. The included features emphasize compatibility with solar, home energy, and recreational vehicle applications.
Key notes: Optimal for stacked configurations and environments where maintenance-free operation is preferred. Ensure proper cabinet or rack spacing for heat dissipation and verify terminal compatibility with your existing battery hardware.
VMAXTANKS 6 Volt 225Ah AGM Battery
VMAX Golf’s VMAXTANKS model is designed for long life in heavy-duty cycles, offering a 9.5″ x 7.3″ x 11″ form factor with a 225Ah rating. The product description highlights a maintenance-free design with an electrolyte suspension system (AGM) that enhances safety and reliability across float and cyclic use. Heavy-duty grids and lead-tin alloys are touted to extend service life even after multiple deep discharges, making it a strong option for golf carts and solar energy storage in remote locations.
Key notes: This battery emphasizes endurance and robustness in frequent cycling. Confirm physical fit and terminal orientation for your charger and mount setup.
Mighty Max ML200-6GC2 6V 200Ah
Mighty Max Battery ML200-6GC2 delivers 200Ah at 6V with internal threading for secure mounting. It’s described as sealed lead-acid (SLA) with AGM, designed for deep cycling and maintenance-free operation. The 10.25″ x 7.00″ x 9.75″ footprint suits compact golf cart compartments and RV storage bays. The internal thread terminals simplify attachment of winches, connectors, or bus bars without additional adapters, and the battery acknowledges wide operating temperatures with a strong discharge and recovery profile for repeated use.
Key notes: Check your terminal layout and screw compatibility. This model is well-suited for systems requiring a compact, modular 6V block with reliable deep-cycle performance.
US2200 XC2 6V 232Ah
PowerStar’s US2200 XC2 pack provides 232Ah at 6V, positioned as a solid GC2 deep-cycle replacement with a rugged polypropylene case. The unit features molded-in UTL terminals for secure connections and is designed for long cycle life in golf carts and solar setups. The four-pack offering makes it an attractive choice for larger installations or multi-battery configurations where uniform performance is essential.
Key notes: Verify compatibility with existing battery trays and charging profiles. The four-pack option is useful for scalable builds but requires careful monitoring of balance and charging to maximize life.
Trojan T105-AES 6V GC2 Deep-Cycle AGM
The Trojan T105-AES is a trusted name in deep-cycle AGM batteries, offering 207Ah at 6V in a GC2 format. Marketed as a long-life, maintenance-free option for golf carts and stationary storage, it emphasizes extended cycle life and reduced maintenance compared with conventional flooded cells. Trojan’s reputation and balance of capacity and reliability position it as a mainstream choice for owners seeking established performance and widespread compatibility with existing Trojan accessories and chargers.
Key notes: Trojan’s support ecosystem and familiar replacement fit can simplify procurement and maintenance. Assess cycling needs and charging strategy to optimize longevity.
Buying Guide: Key Purchase Considerations
When choosing a 6V AGM deep cycle battery, consider how you will use the system, required lifespan, and installation constraints. Most hobby and professional setups demand a balance of capacity, depth of discharge, and durability to handle frequent cycling and environmental conditions.
Capacity and depth of discharge
Capacity (Ah) determines how long a battery can deliver power between charges. For 6V blocks used in series or standalone, aim for higher Ah if you run powerful equipment or plan long off-grid periods. AGM chemistry supports deep cycling, but maximizing life involves avoiding sustained deep discharges beyond recommended limits.
Cycle life and maintenance
Look for design features that extend cycle life, such as robust grids and AGM electrolyte suspension. Maintenance-free operation is a major advantage of AGM batteries, reducing the need for water top-ups and venting concerns in enclosed spaces.
Physical size, weight, and mounting
Ensure the battery fits the tray, enclosure, or rack in your RV, golf cart, or shed. Check dimensions, weight, and terminal layout (top vs. side, post type, threading) to confirm compatibility with your hardware and connectors.
Terminal type and compatibility
Terminal configuration affects ease of wiring and safety. Some models offer internal threading for secure mounting, while others use standard terminals requiring adapters. Match terminals with your insulation and bus bars to minimize resistance and heat buildup.
Voltage compatibility and system design
6V batteries are commonly wired in series to create 12V or higher systems, or used singly in modular designs. Plan your charger profile and solar controller compatibility to maintain balanced charging across multiple units and avoid mismatched aging effects.
Durability and environmental tolerance
Consider operating temperature ranges and vibration resistance, especially in mobile setups like golf carts or RVs. AGM batteries are generally more tolerant of vibration than flooded equivalents, but proper mounting reduces wear and extends life.
Across these options, aim for a balanced purchase that aligns with your expected cycling frequency, storage needs, and ease of maintenance. The models listed provide a spectrum of capacities and mountings to fit typical 6-volt deep cycle applications, from compact RV setups to larger solar-storage projects.
