Our Deep Cycle Battery Watering kits are specifically designed for 12V systems made from two 6V deep cycle batteries, and they're compatible with popular brands like Trojan Plus. Before you purchase, we recommend checking your battery bank's configuration and voltage to make sure it matches. Each kit comes with clear instructions and all the necessary components for easy installation. If you’re unsure about compatibility, our expert support team is always ready to help you select the right system for your golf cart, RV, pallet jack, floor scrubber, or small solar setup.

The Flow-Rite Pro-Fill single-point watering system takes the hassle out of battery maintenance. Instead of removing vent caps and checking each cell individually, you simply connect the Pro-Fill system to your preferred Millennium water supply (gravity tank, hand pump, or pressurized cart), and all cells are filled quickly, evenly, and safely. This process helps prevent overfilling or underwatering, extends your battery life, reduces mess and risk of acid exposure, and saves you valuable time. It’s the best way to keep your golf cart, RV, or warehouse equipment running reliably.

Installing a PowRparts Deep Cycle Battery Watering kit is straightforward—even if you’re new to battery maintenance. Each kit includes step-by-step instructions and all the parts you need. Most customers can complete installation with just basic hand tools in about 30 minutes. Once it’s set up, ongoing battery maintenance is safer and much faster: simply connect your water supply and the Pro-Fill system takes care of the rest. If you have questions, our expert team is just a call or email away, and we offer fast shipping on all kits and replacement parts, so you can buy with confidence and keep your system up and running without hassle.
