As the world moves towards greener energy solutions, electric bikes have gained significant popularity. Their convenience, reliability, and eco-friendly characteristics make them an optimal choice for many. Powering these electric bikes are the heart of the system – the batteries. The 36V 12Ah Electric Bike Waterproof Lithium-Ion Battery Pack with a BMS System + 42V 2A Charger stands out for its top-notch features. This review will cover the main features, specifications, and the overall performance of the battery.

Specifications and Design

The 36V 12Ah Electric Bike Waterproof Lithium-Ion Battery Pack measures 210×76×66 mm and weighs about 1.8 kg, making it relatively compact and light for its capacity. The battery comprises 40 cells (4-parallel 10-series), each with a specification of 3.7V 3.0A. Its discharge port has a T plug and can handle a maximum continuous discharge current of 15A, with an instantaneous peak of 45A. Its nominal capacity and voltage are 12000mAh and 36V, respectively.

The battery pack also includes a 42V 2A Charger, making charging convenient and quick, with a full charging cycle completed in about three hours. It also has built-in features for regulating the charging cycle (CC-CV), and it has limitations for both the discharge cutoff voltage (30+-1V) and the charge cutoff voltage (42V).

Features and Performance

Similar to most high-performing Lithium-Ion batteries, this one has several outstanding features that make it competitively advantageous. For starters, its life expectancy is twice that of lead-acid batteries, and the battery design is significantly lighter. This provides an impressive balance between longevity and convenience.

Further, the 36V 12Ah Electric Bike Waterproof Lithium-Ion Battery Pack is equipped with a built-in IC chip that offers advanced battery protection. It automatically prevents overcharging, over-discharging, overheating, and short-circuiting. This system helps to ensure long-lasting battery life and high performance while boosting the overall safety of the battery pack and extending the lifespan of the motor.

Safety, Durability, and Security

Although the lithium-ion battery is lightweight, it is exceptionally robust and resilient to mechanical accidents caused by vibrations, thanks to the built-in battery holder which enhances its shockproof effect. The outer layer, made from waterproof PVC material, provides reliable insulation, corrosion resistance, and wear resistance. This ensures that the battery pack is safer and more environmentally friendly, as it does not contain harmful substances or heavy metals.

Efficiency and Compatibility

The battery pack displays high versatility and compatibility, making it an ideal choice for a variety of applications. Aside from electric bikes, it can also be used on electric scooters, electric skateboards, electric wheelchairs, airplane models, electric tools, battery pack DIY, golf carts, sightseeing vehicles, and electric motorcycles.

Its green technology offers more extended cycle life, with more than 500-800 charging cycles with a life expectancy of up to five years. The rechargeable feature of the battery, coupled with its lack of memory effect, results in a longer and efficient battery life, making it a durable and reliable choice.

Service Guarantee

The 36V 12Ah Electric Bike Waterproof Lithium-Ion Battery Pack boasts of stringent quality control measures and guaranteed quality. If any customer is unsatisfied for any reason, they can contact the company via Amazon to improve their experience. The company stands behind all their products with a 100% service guarantee.


To sum it up, the 36V 12Ah Electric Bike Waterproof Lithium-Ion Battery Pack holds its own among other batteries in its category with its unique features, excellent performance, and impressive service guarantees. It combines the power, safety, flexibility, and environmental-friendliness required by the modern world, made even more convenient by its lightweight build and quick charging time. Whether you are looking for a replacement battery for your electric bike or you need a reliable battery pack for other applications, this product is a worthy choice.
