Max. climb angle
The maximum angle of inclination of the surface at which the vehicle can normally drive up or down (in some models, this parameter is indicated only for one direction, for example, up).
This parameter characterizes the ability of the device to overcome ups and downs. In modern models, it can reach 45 °. At the same time, note that the ability to cope with large angles requires not only powerful motors, but also appropriate design features (in particular, so that the protective cover does not scrape the ground); and for the descent, the second is even more important than the first. Therefore, when choosing a model for frequent driving on slopes, you should pay attention not only to power, but also to the angle of inclination directly stated in the specs.
Also note that at a high load (approaching the maximum), the efficiency of overcoming climbs may decrease. On the other hand, some manufacturers indicate the angle of inclination at the maximum load, and clarify that the light weight of the rider allows you to overcome steeper climbs than originally stated.
Battery capacity
The battery capacity of the device in watt-hours (Wh).
In general, capacity shows the amount of energy that a battery can store. The higher the number, the more energy the battery stores, respectively, the greater the range (see above) and the more time it will take to charge. Note that although watt-hours are used to designate power much less frequently than milliamp-hours (see above), this designation is more reliable, because when evaluating capacity, in this case, the battery voltage is also taken into account (as opposed to counting in mAh). This makes it easy to compare batteries of different voltages. At the same time, do not forget that the energy consumption of different models can also be different, and battery life is easier to evaluate by the directly claimed range.
Voltage
Rated voltage of the battery used to power the machine.
Usually, the more powerful the motors used, the higher the voltage: due to this, it is easier to provide the required battery power (see below). At the same time, this power depends not only on voltage. In addition, manufacturers choose batteries for the specific motor model used to provide the desired performance. Given all this, we can say that this parameter does not matter when choosing a transport. Voltage data may be useful only for battery repair/replacement, finding a charger and other similar tasks.
Power
The power of the motor installed in the device. For models with two electric motors, this paragraph usually indicates their total power.
This parameter is one of the most critical for self-balancing transport. On the one hand, powerful motors improve the efficiency of balancing (especially with the large weight of the rider), allow you to reach high speed, effectively overcome bumps in the road and climb hills. On the other hand, they weigh a lot, are expensive and require capacious batteries to ensure a decent range (which further affects the weight and price of the entire unit). Therefore, motor power, usually, directly depends on the price category of a particular model.
In fact, the more powerful the motors, the better, and the question of choice for this parameter depends primarily on the price.
Dustproof, waterproof
The level of
waterproof (more precisely — dust- and waterproof) provided by the body of the device.
This parameter is usually designated according to the IP standard; while the first digit indicates protection against ingress of dust and foreign objects, and the second — resistance to moisture. Here are the options for the first parameter found in modern models:
— 5 — dustresistant(a small amount of dust can penetrate inside the case, but does not affect the operation of the hardware)
— 6 — full dustproof.
Indicating more modest indicators in general does not make sense. Moisture resistance options can be as follows:
— 4 — protection against water splashes from any direction (allows you to ride in shallow puddles);
— 5 — protection against water jets from any direction;
— 6 — protection against strong jets and waves.
It should be noted that even well-protected models may have certain application features and restrictions due to weather and other conditions. Therefore, before use, you must familiarize yourself with the relevant section of the instructions, even if a rather high level of protection is claimed in the specs.
