Installation Methods Review: So far so good - I had my son buy one of these about a year ago it is a little slow recovering after recharging my golf cart batteries but after having power applied for about15 minutes it self adjusts and will give a good representation of power consumed. I have not experienced that issue with the new one I put on my son’s golf cart. These power meters are from the same company and have identical product numbers. I hope the new one lasts as well as the old one. Review: great product! - Perfect replacement size. Can see very easy and works well. very easy to install. ## Features - LED BATTERY INDICATOR---- It is a useful device to help you to know how much battery power have left by 10 LED bars with 3 colors(1 red 2 yellows 7 greens,each bars indicate 10% battery power); It is applicable to 48V lead acid battery(not trojan) powered machines. - BATTERY STATE OF CHARGE & DISCHARGE---- It display battery charge status by LED bars step up,and display battery discharge status by LED bars step down.

I have not experienced that issue with the new one I put on my son’s golf cart. These power meters are from the same company and have identical product numbers.

Can see very easy and works well. very easy to install. ### ⭐⭐⭐⭐ Works as described. *by G***T on October 9, 2025* Works as described. Time will tell on longevity. Lights are bright. To bright in the dark, hard to determine what bar is lit. Note: people are complaining that the meter doesn’t read correct while charging. My oem meter does the same as it needs to be refreshed. My club car has a transport toggle switch. Just a click off and on and it refreshes the meter, no need to unplug the negative wire to refresh as others mentioned. ## Frequently Bought Together - Runleader 48V LED Battery Power Indicator, Battery Charge and Discharge Indicator, Applicable to Lead Acid Battery Powered Golf Carts, Forklift, Lawn Mower, Leaf Cutter, Motorhome etc. - CLUBRALLY 36V Powerwise Charger Receptacle Fit for EZGO Medalist TXT Electric Golf Carts --- ## 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.it/products/73569121-rl-bi003-48v-led-battery-indicator](https://www.desertcart.it/products/73569121-rl-bi003-48v-led-battery-indicator) --- *Product available on Desertcart Italy* *Store origin: IT* *Last updated: 2026-07-06*
