Universal 48-volt golf cart battery watering kit for non-standard spacing. Custom-fit system with 360-degree swivel tees. No manifolds required. Hand pump sold separately.
The Flow-Rite BG-U48V-4A Universal Pro-Fill Battery Watering System is the ultimate solution for 48-volt golf carts with non-standard battery configurations. Unlike fixed-spacing kits that use rigid manifolds, this universal system features 24 individual 3-port swivel tees that rotate 360 degrees, allowing you to create custom tubing paths that perfectly match any battery cell spacing or layout. This flexibility makes it ideal for six 8-volt batteries with irregular spacing, offset cells, or tight installations where standard manifolds won't fit.
Each valve features automatic shut-off technology that independently monitors water level and closes when the precise electrolyte level is reached. The winged design provides tool-free installation with visual confirmation of proper seating, while integrated flame arrestors and de-gas chambers ensure safe operation. This system is perfect for golf carts with custom battery trays, mixed battery brands with different spacing, or any 48V application where standard 2.3" or 2.5" manifold kits don't fit.
24 rotating swivel fittings adapt to any cell spacing or battery layout - no manifolds needed
Works with any non-standard spacing, offset cells, or irregular 48V golf cart configurations
Built-in chamber expels hydrogen and oxygen gases naturally, reducing ignition risk
Optimized for 48V golf carts with custom battery trays or non-standard layouts
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: • 48-Volt golf cart systems • (6) Eight-volt batteries • Non-standard cell spacing (any spacing) • Batteries with irregular or offset cell patterns • Tight installations where manifolds won't fit • Custom battery trays or modified golf carts • Mixed battery brands with different spacing When to Choose Universal: If your 48V golf cart batteries have non-standard spacing, offset cells, irregular patterns, mixed battery brands, custom battery tray modifications, or if standard manifold kits (2.3" or 2.5") don't fit your battery layout. The 360-degree swivel tees allow custom routing around obstacles and adapt to any configuration. Measurement: Cell spacing is the distance from center of one cell to center of adjacent cell. If your spacing varies, doesn't match 2.3" (Trojan) or 2.5" (standard) patterns, or if you have mixed battery types, this universal kit is your solution.
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 24 cells 3. Install Pro-Fill Valves: Hand-thread each winged valve into battery cells - wings provide visual confirmation when fully seated 4. Attach Swivel Tees: Connect 3-port swivel tee to each valve - tees rotate 360 degrees for flexible positioning 5. Plan Tubing Routes: Determine optimal tubing paths considering battery layout and obstacles 6. Cut and Connect Tubing: Cut polypropylene tubing to appropriate lengths and connect swivel tees together using tubing 7. Install End Caps: Place red end caps on unused swivel tee ports 8. Mount Coupler: Position quick-disconnect coupler at accessible location for filling 9. Test System: Connect water supply and perform first fill to verify all valves shut off properly Installation Time: 45-75 minutes depending on battery layout complexity. Swivel tees add flexibility but require custom routing planning for 24 cells.
• 24 Pro-Fill valves (winged) • 24 Three-port swivel tee fittings • 10 feet polypropylene tubing (cut to fit) • 1 Quick-disconnect coupler • 9 Red end caps • Complete installation instructions • 3-Year limited warranty Universal Design: No manifolds included - the 360-degree swivel tees provide maximum flexibility for any battery spacing or layout. Cut tubing to exact lengths needed for your specific 48V configuration. Water Supply NOT Included: Choose from hand pump, gravity tank, or regulated hose supply (all sold separately) based on your application needs.
The 360-degree swivel tees in the universal kit provide unmatched installation flexibility for 48V golf carts. Each tee rotates independently, allowing custom tubing routes that adapt to any battery layout, obstacle, or space constraint found in custom or modified golf carts.
Choose BG-U48V-4A (this kit) for non-standard spacing, offset cells, irregular patterns, or mixed battery configurations. Choose fixed-spacing kits (BG-U48V-5A, BG-U48V-6A, or BG-U48V-1A) if your batteries have consistent standard spacing.
