Complete 36-volt golf cart battery watering kit with automatic shut-off valves. Designed for (6) 6V batteries with 2.7" cell spacing. Hand pump sold separately.
The Flow-Rite BG-U36V-1A Pro-Fill Universal Battery Watering System transforms battery maintenance from a dangerous, time-consuming chore into a simple 60-second task. Specifically engineered for 36-volt golf cart applications with six 6-volt batteries, this complete system replaces traditional vent caps with automatic shut-off valves interconnected by tubing. Fill all 18 battery cells from a single connection point without ever removing caps, exposing yourself to acid, or risking over or under-watering.
Each valve independently monitors its cell's water level and automatically closes when the precise electrolyte level is reached, ensuring perfect fills every time. The winged bayonet design allows tool-free installation with visual confirmation of proper seating, while flame arrestors prevent external sparks from igniting flammable battery gases. The pre-spaced manifolds with 2.7" spacing match standard 6-volt battery cell patterns - this is the most common 36V golf cart configuration, fitting most Club Car, EZ-GO, Yamaha, and other 36-volt golf carts with standard 6V batteries.
Fill all 18 cells in under a minute from single connection point - no cap removal required
Automatic shut-off valves independently close when each cell reaches precise water level
Never touch batteries or breathe toxic fumes - fill safely from remote location
Winged bayonet valves install by hand with visual indicators for proper seating
If installing on brand new batteries, you MUST wait at least 4 complete charge cycles before adding any water through this system. New batteries require an initial break-in period where the plates activate and electrolyte levels stabilize. Installing and using the Pro-Fill system immediately on new batteries can result in improper water levels during this critical formation period, potentially damaging the batteries and voiding warranties. After 4 charge cycles, the batteries are ready for normal Pro-Fill operation.
This Kit Is Designed For: • 36-Volt golf cart systems • (6) Six-volt batteries • 2.7" cell spacing (distance between cells) • 3 cells per 6V battery = 18 total cells Most Common 36V Golf Cart Configuration: This (6) 6V battery setup with 2.7" cell spacing is the most common 36V golf cart configuration, fitting the majority of Club Car, EZ-GO, Yamaha, and other 36-volt golf carts. The 2.7" cell spacing is standard for 6-volt golf cart batteries (except Trojan Plus which uses specialized 127-flex manifolds). Why 6-Volt Batteries for Golf Carts: 6-volt batteries are the traditional and most widely used configuration for 36V golf carts. They offer proven deep-cycle performance, wide availability, lower per-battery replacement cost, and easier individual battery handling compared to larger battery formats. Measuring Cell Spacing: Cell spacing is measured from the center of one cell to the center of the adjacent cell. 2.7" is the standard spacing for 6-volt batteries. Confirm your battery spacing before ordering to ensure proper manifold fit.
ALWAYS use distilled or deionized water when refilling your batteries. Tap water contains minerals (calcium, magnesium, iron) that will coat the battery plates and fill pores, preventing proper contact with the electrolyte solution. This mineral buildup causes: • Reduced battery capacity and runtime • Shortened battery lifespan • Increased internal resistance and heat • Permanent damage not covered by warranty Distilled water costs approximately $1-2 per gallon at grocery stores and is essential for maximizing your battery investment. Using tap water will void most battery warranties.
Installation Steps (No Tools Required): 1. Ensure Batteries Are Fully Charged: Install only on fully charged batteries with proper water levels 2. Remove Existing Vent Caps: Unscrew and remove all original battery vent caps from all 18 cells 3. Install Pro-Fill Valves: Hand-thread each winged bayonet valve into battery cells - wings provide visual confirmation when fully seated 4. Install Manifolds: Connect 6 pre-spaced manifolds (one per battery) to the 3 valves on each 6V battery 5. Connect Tubing: Cut polypropylene tubing to appropriate lengths and connect manifolds together, terminating at coupler location 6. Install End Caps: Place red end caps on unused tubing connection points 7. Mount Coupler: Position quick-disconnect coupler at accessible location for filling 8. Connect Water Supply: Attach your chosen water supply (hand pump, gravity tank, or regulated hose supply sold separately) 9. Test System: Perform first fill to verify all valves shut off properly Installation Time: 25-40 minutes for experienced users, 40-60 minutes for first-time installation on 6-battery golf cart systems.
• 18 Pro-Fill valves (winged bayonet) • 6 Manifolds (2.7" spacing, one per 6V battery) • 7 feet polypropylene tubing (cut to fit) • 1 Quick-disconnect coupler with dust cover • 9 Red end caps • Complete installation instructions • 3-Year limited warranty Water Supply NOT Included: Choose from hand pump, gravity tank, or regulated hose supply (all sold separately) based on your application needs.
This BG-U36V-1A kit is the most common 36V golf cart configuration - (6) 6-volt batteries with 2.7" standard cell spacing. Measure your battery's cell spacing before ordering to ensure proper fit.
The (6) 6V battery configuration with 2.7" spacing is standard across most 36-volt golf cart brands. This Pro-Fill kit fits the vast majority of 36V golf carts with standard 6-volt batteries.
