Learn how to charge and care for your FLEX Kart 6-volt battery ride-on to keep it running safely and extend its life. Simple steps for battery care, cleaning, and storage.

Quick answer

Charge the FLEX Kart's 6-volt battery fully before first use and after every ride, and store the vehicle in a cool, dry place to keep it running safely for years.

Why battery care matters for ride-on vehicles

The FLEX Kart runs on a 6-volt battery that powers speeds up to 2 mph. Like all rechargeable batteries, it lasts longest when you follow a few simple habits. Overcharging, deep discharging, or leaving the battery in extreme temperatures can shorten its life and reduce ride time.

Because the FLEX Kart folds for storage, it's easy to tuck away — but don't forget to disconnect and store the battery separately if you won't ride for several weeks. That small step prevents battery drain and keeps the vehicle ready to go.

Step-by-step: How to charge and maintain your FLEX Kart

Charge the battery fully before first use: Plug the included charger into the battery port and then into a wall outlet. Charge for the full time recommended in the manual (typically 8–12 hours for the first charge). A common mistake is stopping early — an incomplete first charge can reduce future battery capacity.
Charge after every ride, even if it's short: After each use, recharge the battery completely. Do not store the vehicle with a partially charged battery. Letting the battery sit partially drained accelerates wear and may lead to a shorter overall lifespan.
Unplug the charger once charging is complete: Once the battery is full, disconnect the charger from the wall and the vehicle. Do not leave it plugged in for days. Overcharging can overheat the battery and damage its cells over time.
Clean the vehicle after outdoor use: Wipe down the FLEX Kart with a damp cloth to remove dirt and debris. Do not use a hose or pressure washer — water can damage the electrical components. Moisture in the battery compartment or motor is a common cause of ride-on failure.
Store the battery separately for long breaks: If you won't use the FLEX Kart for a month or more, remove the battery and store it in a cool, dry place (between 50°F and 80°F). Charge it to about 50% before storage. Extreme heat or cold drains the battery and can cause permanent damage.
