Looking for the best price on Li-ion batteries online in India? Robocraze stocks a wide range of lithium-ion cells and battery packs — including popular form factors like 18650 and 21700 — across varying capacities and discharge ratings, all at competitive prices with fast delivery across the country. Pricing varies based on capacity (mAh/Wh), continuous discharge current rating, and brand. Whether you're powering a drone, a robotics build, an RC vehicle, or a DIY power bank, comparing options in one place ensures you find the right cell for your application without overpaying.

Are Li-Ion Batteries from Robocraze Original and Genuine?

Yes. Every Li-ion battery sold through Robocraze is a genuine, branded cell sourced from established manufacturers with verified safety and performance credentials. Authentic batteries deliver their rated capacity, maintain stable discharge performance across charge cycles, and include built-in protective circuitry against overcharge, over-discharge, and short circuits. Counterfeit or low-quality Li-ion cells are a serious risk — not just to your project, but to personal safety. Fake cells routinely underperform their rated capacity, overheat under load, and in worst cases pose fire or explosion risks. Always source Li-ion batteries from a trusted, reputable supplier.

Li-Ion Battery Specifications — What to Compare

Li-ion batteries differ across several parameters that determine suitability for your application. Capacity — measured in mAh or Wh — determines how long the battery can power your device before needing a recharge; higher capacity means longer runtime. Nominal voltage is typically 3.6V to 3.7V per cell, with pack voltage determined by the number of cells in series. Continuous discharge current rating is critical for high-demand applications like drone motors or power tools — a cell that can't sustain the required current will sag in voltage, overheat, or fail prematurely. Form factor matters for physical fit — 18650 is the most widely used cylindrical cell, 21700 offers higher capacity in a slightly larger package, while pouch cells suit custom pack configurations. Finally, check whether the cell includes onboard protection circuitry, particularly for microcontroller and robotics applications where accidental over-discharge is a real risk.

Li Ion Battery 18650 – Compact Power for Modern Devices

A li ion battery 18650 is one of the most widely used rechargeable battery formats, known for its cylindrical shape and high energy density. The term “18650” refers to its size—18mm diameter and 65mm length—making it compact yet powerful for various electronic applications.

These batteries typically operate at a nominal voltage of around 3.7V and offer capacities ranging from 1800mAh to 3500mAh, depending on the model and quality. Their ability to deliver stable voltage and high discharge current makes them ideal for devices like power banks, laptops, flashlights, and DIY electronics projects.

Another key advantage of li ion battery 18650 cells is their long cycle life. Many cells can be recharged hundreds of times with minimal capacity loss, making them cost-effective and environmentally friendly. This reliability has made them a preferred choice in IoT, robotics, and portable electronics.

Rechargeable Li Ion Battery – Efficient and Long-Lasting Energy Solution

A rechargeable li ion battery is designed to provide consistent and reusable power for a wide range of applications. Unlike traditional disposable batteries, these batteries can be charged and discharged multiple times, significantly reducing waste and long-term costs.

One of the biggest benefits of rechargeable li ion battery technology is its high energy density, allowing more power to be stored in a smaller size. This makes them perfect for compact devices such as smartphones, Bluetooth speakers, and embedded systems. Additionally, they maintain a stable voltage output throughout most of their discharge cycle, ensuring reliable performance.

Rechargeable li ion batteries also support fast charging and have low self-discharge rates, meaning they retain charge even when not in use. With proper handling and protection circuits, they are safe and efficient for both consumer electronics and advanced engineering projects, including robotics and automation systems.

1. What is a Li-ion battery charger module?

A Li-ion battery charger module is primarily made for charging rechargeable lithium batteries. This is done using the constant current and constant voltage (CA/CV) charging method. Apart from this Li-ion battery charger module also provides the necessary protection required by li batteries.

2. What are lithium-ion batteries?

A lithium-ion (Li-ion) battery is a high-tech battery that employs lithium ions as an important component of its electrochemistry. Lithium atoms in the anode are ionized and separated from their electrons during a discharge cycle. The lithium ions travel from the anode through the electrolyte to the cathode, where they recombine with their electrons and electrically neutralize. The lithium ions are small enough to pass through a micro-permeable separator that separates the anode and cathode. Because of the small size of lithium (third only to hydrogen and helium), Li-ion batteries can have very high voltage and charge storage per unit mass and unit volume.

A primary battery is a type of electrical cell that cannot be recharged or reused. These are typically composed of one or more electrochemical cells, each with its own electrodes and electrolytes. The chemical reaction inside the battery generates an electric current when it's connected to an external circuit. Primary batteries have been in use since 1799 and come in many sizes, shapes, voltage levels, capacity ratings, and chemistries depending on their purpose - from small button-sized watch batteries all the way up to large industrial applications powering aircraft turbines! Primary batteries are used widely today due to their reliable performance over time even under harsh conditions where other energy sources may falter while providing excellent portability for users who don’t want bulky charging cables trailing behind them wherever they go.

11. What is the secondary battery?

Secondary batteries, otherwise known as rechargeable batteries, are an essential component in our ever-growing technological world. Used to store energy and provide power for a variety of portable devices such as mobile phones or tablets, secondary batteries can be recharged multiple times with no significant degradation over time - allowing them to run longer on one charge than primary cells. Given their longevity and cost savings potential compared with single use disposable alternatives, these types of battery technology have become popular across industries from consumer electronics right through to aerospace applications. With advances in biodegradability and increasing efficiency that is encouraging clean technologies too; it’s clear why the demand for secondary batteries continues to rise rapidly today.

Absolutely. Many of the batteries are explicitly mentioned for use in DIY electronics, IoT modules, robotics, drones and similar builds. Higher voltage packs (like 11.1 V) make them especially suited for motors, drones and high-drain loads, while single-cell packs are great for backup power, microcontrollers and sensor systems.

15. What safety measures should I take while using these batteries?

Because lithium-ion batteries have high energy density, they require safe practices. Use a proper charger designed for Li-ion chemistry (constant current/constant voltage method). Avoid over-charging (charging beyond recommended voltage) and over-discharging (going below safe cut-off voltage). Never short the terminals or puncture the battery. Monitor for swelling, overheating or unusual behaviour. For drone or motor applications, ensure current draw and battery rating match so you don’t exceed safe limits.

16. Are these batteries compatible with Arduino/Raspberry Pi projects?

Yes — single-cell lithium-ion packs (3.7 V nominal) and regulated versions can work perfectly with Arduino and Raspberry Pi (often via a 5 V regulator if needed). For higher-voltage packs (e.g., 11.1 V) you may need voltage-regulation or step-down converters before supplying microcontrollers. Many listings mention use with IoT boards and electronics modules.
