The 36V voltage specification is a classic mainstream configuration for Citycoco fat-tire electric scooters for entry-level commuting and leisure travel. Featuring low-voltage safety, energy saving, stable cruising and wide compatibility, it is the preferred choice for short-distance household travel, student commuting and urban leisure riding, covering most civilian light-load working conditions such as urban flat road cruising and slight bumpy road riding. While the battery cells determine energy storage and endurance performance, the circuit and interface system acts as the only power transmission channel, directly controlling the overall vehicle power output, charging safety and operational stability, making it an indispensable core component. Most ordinary 36V Citycoco batteries adopt low-grade and simple circuit and interface solutions with inferior copper-clad aluminum wires, exposed ordinary plugs, non-locking docking structures and basic welding craftsmanship. These designs have inherent defects such as thin wire gauge, uneven conductivity, loose interface connection and insufficient protection. Under conditions of frequent plugging and unplugging, continuous bumpy vibration and humid dusty outdoor environments, they are prone to poor interface contact, instantaneous power failure, power stuttering and false full charging. Long-term use will further cause wire aging and cracking, interface corrosion and electric leakage, as well as short-circuit overload hazards, seriously affecting riding experience and driving safety. Customized exclusively for 36V Citycoco fat-tire scooters, this battery features a fully upgraded circuit and interface system as its core highlight. It achieves comprehensive optimization in wire material, interface structure, locking design, welding technology, sealing protection, circuit layout and compatibility, building a professional power transmission system with high safety, stability, low loss and long service life. It thoroughly solves frequent circuit and interface faults of ordinary batteries and provides long-term safe and smooth power transmission guarantee for 36V low-voltage scooter models.

High-spec thickened pure copper wires ensure low resistance, low energy loss and lossless power transmission. As the carrier of power transmission, wire material and gauge directly determine conductive efficiency and load capacity. Ordinary 36V batteries generally adopt thin inferior alloy wires or copper-clad aluminum wires with large resistance, weak current-carrying capacity and severe heat generation. They cannot adapt to the normal current output of daily start-stop and constant cruising, easily causing power loss, power attenuation and wire overheating aging after long-term use. This 36V battery is fully equipped with thickened high-purity oxygen-free pure copper cores with wire gauges precisely matching the rated current of 36V low-voltage batteries. It features low resistance, fast conduction, stable current carrying and low heat generation. The high-quality pure copper wires are anti-oxidation, anti-corrosion and anti-fatigue, resisting internal wire breakage and conductor aging caused by repeated bending and vibration pulling. It can stably bear the continuous current and instantaneous starting current during daily riding, greatly reducing heat loss and power waste during power transmission. It effectively avoids false range and weak power, ensures efficient power delivery to the motor with linear and stable power output, and eliminates heating risks from the source to improve overall power safety and energy utilization.

Self-locking precision interface structure realizes anti-vibration and anti-loosening performance to eliminate power failure on bumpy roads. Facing the high-frequency bumpy and vibrating riding conditions of Citycoco scooters, ordinary non-locking plug interfaces rely only on simple insertion and fitting, which are easy to loosen and lose contact under vibration, causing instantaneous power cut, power stuttering and sudden flameout. This battery adopts an upgraded buckle self-locking interface structure with precise male and female terminal adaptation. The plugs lock automatically after docking to form an integrated firm connection without extra tape or cable ties. Built with precision spring buckles and clamping grooves, it supports smooth plugging and unplugging with accurate positioning. Users can confirm stable connection with a clear locking click, and unlocking requires manual pressing to prevent accidental disconnection. It maintains tight zero-loose fitting under complex conditions such as bumpy roads, off-road vibration, body shaking and high-frequency start-stop, completely solving the common industry problems of unstable contact and fluctuating power caused by vibration, and ensuring continuous and stable power transmission to greatly improve riding fluency and control stability.

Integrated precision welding technology ensures firm connection and eliminates virtual welding and desoldering risks. The welding process of circuits and interfaces determines the durability and stability of circuit connection, which is the key to avoiding circuit faults. Low-end ordinary batteries adopt simple manual spot welding with thin solder points and small contact areas, which are prone to desoldering, wire breakage and poor contact under slight pulling and vibration. This 36V battery adopts industrial automatic laser spot welding technology with full, firm and fully attached solder joints, eliminating process defects such as virtual welding, missing welding and cold welding. All circuit joints are reinforced with overlay welding for high tensile resistance, vibration resistance and temperature resistance, avoiding solder cracking, wire falling off and contact failure caused by long-term vibration and temperature changes. Meanwhile, all welding positions are wrapped with insulating protection to prevent exposed solder oxidation, short circuit and electric leakage, permanently maintaining stable circuit conduction and extending the service life of the circuit system.

IP67 full-sealed waterproof and dustproof interface realizes all-weather protection for complex outdoor conditions. Most 36V scooters are used for daily outdoor commuting. Ordinary exposed interfaces lack protective measures, allowing water vapor and dust to easily invade the gaps, causing shrapnel oxidation and corrosion, increased contact resistance, abnormal charging and short-circuit electric leakage. This battery interface adopts industrial-grade IP67 full-sealed protection design with thickened high-elastic silicone gaskets and fully covered protective shells, completely blocking the invasion of rainwater, stagnant water, dust, fog and sediment. It effectively avoids interface damp corrosion, short circuit and poor contact in rainy riding, waterlogged roads and dusty outdoor environments, preventing power failure caused by harsh weather. The interface shell is made of high-strength flame-retardant and wear-resistant material with excellent compression, drop and aging resistance, maintaining intact performance under long-term sun exposure and rain erosion to achieve stable all-weather protection.

Standardized integrated circuit layout prevents wear and bending to avoid premature circuit aging. Ordinary 36V batteries adopt disordered circuit layout with randomly bent and suspended wires. Long-term riding vibration causes repeated wire bending, friction wear and shell cracking, leading to electric leakage, short circuit and wire breakage. This battery features a scientific integrated circuit layout with standardized wiring routes and reasonable bending radian, avoiding sharp bending, excessive distortion and suspended tension. Equipped with exclusive wire limiting slots and harness fixing structures, it organizes and fixes redundant wires neatly to prevent friction and wear between wires and the shell or vehicle body. The reserved reasonable bending margin adapts to battery disassembly and vehicle vibration deformation, eliminating wire tension fatigue and breakage risks. It fully protects circuit integrity, delays aging and maintains neat wiring and stable conduction in long-term use.
