Flow-Rite BG-U48V-1A 48V Battery Watering Kit for 8x 6V or 4x 12V Batteries, 2.7" Cell Spacing

Flow-Rite BG-U48V-1A 48V Battery Watering Kit for 8x 6V or 4x 12V Batteries, 2.7" Cell Spacing

The Flow-Rite BG-U48V-1A is a 48V battery watering kit made to help keep battery water levels at the proper point. This kit is designed for systems with eight 6V batteries or four 12V batteries and uses 2.7 inch cell spacing.

This kit includes valves and the necessary tubing for installation. The valve design helps add the correct amount of water to each cell, and the tubing helps make battery watering faster and cleaner. It is a practical choice for routine battery care on deep cycle battery systems.

Key Features

• Automatic Shut-Off Valves: Each valve independently closes when its cell reaches proper water level - eliminates over or under-watering
• Single-Point Filling: Fill all 24 cells simultaneously from one remote connection point without removing any caps
• Winged Bayonet Design: Tool-free hand installation with wings providing visual confirmation of proper valve seating
• Integrated Flame Arrestors: Built into each valve to prevent external sparks or flames from igniting hydrogen gas produced during charging
• Quick-Disconnect Coupler: Snap-on/snap-off connection for water supply - no threading or tools required
• Under 60-Second Fill Time: Complete all 24 cells in under a minute versus 10-15 minutes manually filling each cell
• Acid-Resistant Tubing: Clampless polypropylene construction resists battery acid and withstands below-freezing temperatures
• Pre-Spaced Manifolds: 6 manifolds with 2.5" spacing match standard 8V battery cell patterns for fast installation
• Golf Cart Optimized: Specifically engineered for golf cart battery configurations and access constraints
• Safety Enhancement: Eliminates acid exposure, toxic fume inhalation, and risk of spills during filling
• Extended Battery Life: Proper water levels every time maximizes battery performance and lifespan
• Made in USA: Manufactured by Flow-Rite Controls in Byron Center, Michigan
• 3-Year Limited Warranty: Manufacturer warranty covers defects in materials and workmanship

CRITICAL: New Battery Break-In Period 

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.

CRITICAL: Water Type Requirements

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.
