We do not recommend modifying our chargers in any way. We offer a variety of cart-specific charging ports to facilitate easy installation of our chargers and batteries.

Replacement with new or larger cables may be recommended based on the cart’s age, condition, and configuration:
● Replace cables if they show signs of aging or corrosion.
● Larger cables are highly recommended if you’ve upgraded your cart with larger tires, additional seats, increased load capacity, a higher-amperage controller, a larger motor, or any modifications that increase current draw.

Required parts include:
● HIO Battery lithium battery
● Battery charger
● LCD monitor
● Voltage converter (if your cart has lights or a stereo and no existing converter)
● Basic hand tools
*Note: This is not an exhaustive list. Additional parts, components, or tools may be required for your specific application.

1. Remove the seat, turn off the cart with the key, and switch the cart to tow mode.
2. Take a photo of the existing battery installation for reference.
3. Disconnect and remove the lead-acid batteries.
4. Ensure the HIO battery’s power button is in the off position (no blue light).
5. Attach the mounting brackets to the underside of the commercial battery, with the slot side down and facing away from the battery.
6. Position the battery in the tray, ensuring the main positive and negative cables can reach the battery terminals. You may need to adjust the brackets for a proper fit. Note: If cables are too short, longer cables must be purchased. If cables are cracked or rusted, replacement is highly recommended.
7. Secure the other side of the mounting brackets to the golf cart frame using the provided hardware.
8. Connect the 48V positive cables to the red terminal and 48V negative cables to the black terminal, then tighten. Note: Do not connect 12V accessories (horn, lights, etc.) directly to the battery. 12V accessories must be connected to a 48V to 12V step-down converter.
9. Press the power button (blue light illuminates) and switch the cart to run mode.
10. Verify that accessories (lights, horn, etc.) are functioning properly.
11. Replace the seat and confirm the cart operates in forward and reverse.
12. Download the HIO Battery E-BMS app and connect to the battery.
13. Plug in the HIO charger and confirm charging. A positive amp reading on the left side of the screen indicates charging (initial current is typically 10A to 15A). Always charge the battery to 100% (steady green light) before first use.
14. The battery is fully charged when the charger’s green light remains steady (not blinking) and the app shows 100%. Unplug the charger at this point.

Search for the "E-BMS" app on your smartphone and install it. Open the app, enable Bluetooth access, and choose to register an account or use guest mode to access the main interface. The interface displays charging status to confirm if the battery is charging. For more information you can go through the User Manual or the Bluetooth introduction interface on our website

Runtime varies by course terrain. Typical performance:
● 54Ah capacity: 27-33 holes, including travel to and from the course
● 105Ah capacity: 54 holes, including travel to and from the course

No. But If the battery has been stored for extended periods, perform a full charge cycle to calibrate it.（full charge cycle: charge to 80%-100% is ok, but there can't be any discharging during it ）

Our batteries feature a built-in BMS that prevents overcharging and over-discharging. Even so, best practice is to use a lithium-compatible charger and avoid repeated deep discharges.

Latest data: The built-in 200A BMS supports continuous 200A discharge, 400A for 35 seconds, and 600A for 3 seconds (laboratory data). Our supplier’s field tests confirm actual support for 300A discharge for 180 seconds.

It is recommended. Note: Do not connect 12V accessories (horn, lights, etc.) directly to the battery. All 12V accessories must be connected to a 12V step-down converter.

Yes, it works with controllers from 250A to 440A. For longer runtime, go with a higher-capacity battery.

Replacement with new or larger cables may be recommended based on the cart’s age, condition, and configuration:
● Replace cables if they show signs of aging or corrosion.
● Larger cables are highly recommended if you’ve upgraded your cart with larger tires, additional seats, increased load capacity, a higher-amperage controller, a larger motor, or any modifications that increase current draw.

Recommended extension cord specifications:
● Up to 15ft (≈4.6m): 12-14 AWG
● Up to 25ft (≈7.6m): 10-12 AWG
● Extension cords over 25ft are not recommended
For optimal performance, use an HIO Battery dedicated extension cord.

It would be better to use the original one of our brands. Our batteries and chargers are designed to work together. Using third-party chargers or battery tenders may damage the battery or golf cart and void the warranty.

A simple way to calculate charge time: Divide the total Ah capacity of the battery pack by the charger’s amp rating. Example: A 105Ah battery with a 18A charger takes approximately 5.83 hours to fully charge from 0%. Charging from 50% takes ~2.92 hours, from 75% takes ~1.46 hours, and from 25% takes ~4.38 hours. In the same way, if a 105Ah battery with a 12A charger takes approximately 8.75 hours to fully charge from 0%.

Both our chargers and batteries feature built-in monitoring systems to prevent overcharging. Therefore, we only recommend using the compatible charger.

Yes-if the charger is lithium-specific and stops charging once full. Additionally, avoid repeated charging in extreme hot or cold temperatures.

HIO batteries are not recommended to be discharged below 20%. Recharge to 100% if continuing use; but do not fully charge for long-term storage.

Charge the battery after each use. Unplug from the cart once the charger’s green light remains steady.
