Too late to return. Buyers beware ### ⭐⭐⭐⭐⭐ great product! *by D***. on June 2, 2025* Perfect replacement size. Can see very easy and works well. very easy to install. ### ⭐⭐⭐⭐ Overall Good *by 1***2 on August 8, 2026* This battery level meter is surprisingly compact, which made it easy to install. It has worked well as a temporary solution for monitoring my battery setup. The only issue I’ve noticed is that it consistently reads a full charge, even when I know the batteries aren’t completely charged. That said, I’m monitoring six batteries at once, so it’s possible the reading is being affected by my setup rather than the meter itself. Overall, it’s been a good temporary fix and serves its purpose. ## Frequently Bought Together - Runleader 36V LED Battery Power Indicator,Battery Charge & Discharge Display,Applicable to Lead Acid Battery Powered Golf Cart Forklift Lawn Mower Leaf Trimmer Motorhome etc. - Drive-up 36V Powerwise Charger Receptacle for EZGO TXT Medalist Electric Golf Carts (Charger Receptacle) - EPOWREY 18 AMP 36 Volt Golf Cart Battery Charger for EZGO TXT with D Style Plug --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.sk/products/122373253-rl-bi003-led-battery-level-meter](https://www.desertcart.sk/products/122373253-rl-bi003-led-battery-level-meter) --- *Product available on Desertcart Slovakia* *Store origin: SK* *Last updated: 2026-08-13*
