The Caterwil GTS3 Advanced is an improved version of the Caterwil GTS3, designed specifically for exporting to American, European and Middle Eastern countries. The Advanced model includes several features, including the lithium battery, vibration-absorbing pneumatic wheels, and a set of modern LED-headlights. The road performance is also enhanced; the Advanced version of a wheelchair is 20% faster, and has a driving range nearly twice as high as the GTS3. Along with this, the overall weight of the device was reduced by 15 kg.

The most outstanding update in this version is the new lithium battery pack. Compared to the lead-acid battery, the lithium battery pack has a higher capacity rate, a higher supply voltage, a deeper discharge, weighs less, and has a longer service life. The lithium battery has a service life of 1,000 full-charge cycles, versus the 300-cycles of standard AGM and GEL batteries.

Since the new lithium battery allows a higher driving range, the user can ride distances six-times longer using the same battery pack! Furthermore, it uses new lithium cells developed especially for electric vehicles that are more cold-resistant and lose less capacity in extreme cold temperatures.

Another important aspect is the operating comfort of the Caterwil GTS3 Advanced; this enhanced comfort was achieved by using vibration-absorbing pneumatic wheels and updating the software. New tires make driving on rough terrain more comfortable and smoother due to reduced vibration noise.

. The Advanced model also boasts newly designed front lights, the so-called “Angel eyes”, which have two operating modes:
“Running Lights” — when only the blue rim is enabled
“Low-beam“ — when the white headlight is turned on in addition to the blue rim

Rear LED lights have one operation mode and were designed to illuminate the path for reverse movement to provide safe driving. Rear chrome alloy wheels also give a fresh and unique look to the Caterwil GTS3 Advanced.
