48V battery watering system with custom-molded snake tubing and hand pump for Club Car with Crown and US Battery 8V batteries.
The Flow-Rite BG-C48V-21-WS is a complete battery watering system specifically designed for Club Car Precedent and DS (2007 and older) golf carts equipped with Crown or US Battery 8-volt batteries featuring 2.5-inch cell spacing. This kit combines custom-molded snake tubing that perfectly matches Crown and US Battery layouts with a professional 24-inch hand pump featuring a flow indicator. The pre-formed snake tubing eliminates the need for custom cutting and routing, reducing installation time by 50% compared to universal kits.
The shrouded winged bayonet valves install with a simple push and quarter-turn—no tools required. Visual confirmation ensures proper seating on every cell. Once installed, simply connect the included hand pump to fill all six batteries in under five minutes. The automatic shut-off valves ensure each cell reaches optimal water level then stops, eliminating the guesswork and human error associated with manual watering. This system transforms dangerous, time-consuming battery maintenance into a safe, fast, and reliable process.

This BG-C48V-21-WS kit is designed for 2.5-inch cell spacing ONLY. The custom-molded snake tubing is pre-formed for Crown and US Battery 8-volt batteries with 2.5" spacing between cell posts. Using this kit with batteries that have different cell spacing (such as 2.3" or 2.7") will result in poor fit, stressed connections, and potential system failure. Measure Your Battery Spacing: Use a ruler to measure the distance between the centers of adjacent cell posts. If your measurement is approximately 2.5 inches, this kit is compatible. If not, you need a different Flow-Rite kit. Compatible Battery Examples: • Crown CR-220 (8V) • Crown CR-225 (8V) • US Battery US 8VGC XC (8V) • US Battery US 8VGC XC2 (8V) • Other 8V batteries with 2.5" cell spacing NOT Compatible With: • Trojan batteries (typically 2.3" spacing) • Interstate, Duracell, or other brands with different spacing If you have Trojan 8V batteries with 2.3" spacing, order model BG-C48V-11-WS instead.
BG-C48V-21-WS Kit Includes: • 24 Pro-Fill Automatic Shut-Off Valves • 6 Red Manifold Assemblies (One Per Battery) • 1 Custom-Molded Snake Tubing (2.5" Spacing) • 1 Hand Pump (24" with Flow Indicator) • Complete Installation Instructions • Warranty Documentation Ready to Install: This kit includes the complete watering system and water delivery pump—no additional purchases required except distilled water.
Simple Installation Steps: 1. Remove Vent Caps: Take off all battery vent caps, store safely for future use 2. Install Valves: Push shrouded winged valves into cells, quarter-turn until wings snap into place 3. Position Snake Tubing: Lay pre-molded tubing over battery tops—curves match Crown/US Battery layout 4. Connect Red Manifolds: Attach manifold assemblies to valves on each battery 5. Test System: Connect hand pump, fill batteries, verify automatic shut-off and check for leaks Installation time: 30-45 minutes for complete system
How to Use Hand Pump: 1. Prepare Water: Pour distilled water into clean jug or container 2. Insert Pump: Place intake tube into water jug 3. Prime Bulb: Squeeze bulb repeatedly until filled with water 4. Connect: Remove dust cover, snap pump quick-connect to system 5. Pump Water: Squeeze bulb to pump—flow indicator spins when water moves 6. Wait for Shut-Off: When indicator stops spinning, batteries are full 7. Disconnect: Press release, remove pump, replace dust cover
The -WS suffix indicates "With Supply" (hand pump included). Choose the bundle kit for immediate use or the base kit if you already have a Flow-Rite water supply.
Always measure your battery cell spacing before ordering. The manifold color helps identify which kit you have: Black = 2.3" (Trojan), Red = 2.5" (Crown/US Battery).
NEVER use tap water in your batteries! Minerals in tap water coat battery plates, fill microscopic pores, and drastically reduce contact area between plates and electrolyte. This causes permanent capacity loss and can shorten battery life by 40-50%. Approved Water Sources: • Distilled Water (grocery stores, auto parts stores) • Deionized Water (produced with deionizer cartridges) • RO Water (only if TDS meter shows under 10 ppm) DO NOT Use: Tap water, well water, bottled drinking water, softened water New Battery Break-In: For brand new batteries, complete at least 4 full charge/discharge cycles before adding any water. Initial electrolyte levels must stabilize during break-in period.
