Smart^™ Technology Overview

LiPo batteries with Spektrum Smart^™ technology practically take care of themselves. When combined with a Spektrum^™ Smart Battery Charger, the unique parameters, history of the battery and more are all available the instant it's connected. Charging a Smart Battery is easy as it gets, plus Smart LiPo battery packs are programmable to meet your exact charging needs. But the crowning feature of a Spektrum Smart LiPo battery is that it can be programmed to safely self-discharge to storage condition. That's a Smart Battery pack!

Spektrum Smart technology is about offering a higher connection to your hobby. It's a connection that puts you in complete control, makes you more aware and more confident about the capability of your equipment-all the while making your hobby easier. The combined result will make you wish everything about your hobby was "smarter." Spektrum Smart LiPo Batteries are a part of a wide series of Smart technology products now available.

Key Features

Integrated microchip stores unique parameters for each battery
Smart discharge allows batteries to automatically discharge to a safe voltage
Save time and hassle, while improving battery life
Powerful 50C continuous discharge rating to deliver high performance and longevity
Protective outer metal alloy sheet helps dissipate heat, hold battery shape, and increase durability
No soldering required, equipped with IC3 and IC5 Connectors that are compatible with EC3 and EC5
50C battery packs are available in a variety of capacities and cell counts that are perfect for almost any application

Feature Overview

You'll never have to set charge preferences for a Spektrum Smart battery until you want to. When a Spektrum Smart LiPo battery is connected to a Spektrum Smart charger, unique parameters and health of that Smart LiPo battery upload from the Smart memory microchip integrated into the battery. Through the charger, you can view and set preferences, such as charge rates, so that all you have to do to charge the pack every time is press the charger "Start" button. Smart technology takes care of the rest.

Our new Spektrum Smart 50C LiPos come in a variety of popular sizes and are ready to drop into your RC aircraft for better performance, power, and reliability. These are the perfect packs for high performance models and power systems and a great upgrade to get more punch and power on nearly any setup.

Spektrum Smart LiPo Batteries Store Unique Data, Such As:

Battery Brand
Battery Type
Battery Capacity
Battery C Rating
Individual Cell Voltage
Battery Temperature
Charge/Discharge Cycles

Spektrum Smart LiPo batteries also maintain an error log including the number of over-heat, over-discharge and over-charge incidents which can be helpful data in assuring that the battery you've chosen is right for the application. A Smart Battery uploads its charge parameters to a Spektrum Smart Charger automatically making charging as simple as pressing the "Start" button. The charge rate of every Smart Battery is customizable, allowing you to take full advantage of packs with faster charge ratings.

Smart Battery Technology

When connected to a Spektrum Smart charger, unique parameters and health of your Smart LiPo battery upload from the Smart memory microchip integrated into the battery. Through the charger, you can set and record preferred settings, such as charge rates and self-discharge options, so that all you have to do to charge the pack is press the "start" button. Smart technology will take care of the rest. Every Smart LiPo battery is factory assembled with the next-generation IC3^™ and IC5^™ output connector that utilizes a data transfer wire to relay saved information to your Smart Chargers.

Data Rich

An integrated microchip allows each Smart Battery to save vital information such as battery brand, chemistry, cell count, capacity, number of charging cycles, number of discharges, C rating, battery temperature, and internal resistance. Additionally, each battery will save a log of unhealthy events such as over-charge, over-discharge, and over-temperature. This allows you to make the most informed decision about each battery when you are getting your gear ready for a day at the field or the track

Simple and Quick

Preset charge, discharge, and storage parameters are automatically relayed to a Spektrum Smart Charger making charging as simple as pressing the "start" button. Charge rate of individual batteries can be user customized allowing you to take full advantage of packs with faster charge ratings. The integrated microchip on each battery will remember the last charging rate you set, so the next time you plug it in, these settings will automatically populate so all you have to do is press "Start." Another feature that the Smart microchip allows is single-connection balance charge. When you plug in your IC3 or IC5 connector to the charger, individual cell voltage is automatically relayed to the Smart charger and allows you to balance charge without fussing with standard balance connectors.

New IC3 & IC5 Connectors

The innovative Smart connection is made possible by an installed microchip on every battery, feeding the unique information through a data cable to the new IC3 and IC5 connectors. The IC series of connectors are designed from the ground up to provide a more solid connection, higher heat resistance, and effortless installation. For those using the popular EC3 and EC5 connectors, there's no need to worry. The IC connector series is entirely backwards compatible with existing connectors so you can use Smart Batteries with older systems, but only when connected to a Spektrum Smart device are all the benefits of Smart technology obvious.

Smart Discharge

LiPo batteries with Spektrum Smart^™ technology practically take care of themselves. When programmed with a Spektrum Smart Charger, Smart Batteries will automatically discharge to your predetermined storage voltage when they are left to rest for a time period you choose, between 12 and 240 hours. This feature will help to extend the life of your Smart Batteries by preventing your batteries from sitting fully charged for an extended period of time, which can damage the chemical integrity of Lithium Polymer cells. This unique feature results in longer battery life expectancy and better performance over the life of the pack.

For orders above £120, we offer delivery to most mainland UK addresses. For orders under £120, we can still deliver to Northern Ireland and the outlying isles, as long as the item can be sent by Royal Mail, weighs less than 30kg, and fits within 61cm × 46cm × 46cm. Some highland and remote areas may carry an extra delivery charge as couriers often apply surcharges in these locations. If you live in one of these areas, feel free to contact us before ordering so we can confirm the delivery options and costs for you.
Most of our products include delivery in the price. If your order is under £90, a small delivery fee will apply but do not worry this will always be clearly shown at checkout before you complete your purchase.
Depending on what you choose at checkout, your order will usually be delivered either the next working day or within 2 working days. For next day delivery please place your order before 2:00pm. Orders are dispatched Monday to Friday only. Some items may take a little longer and if that is the case we will always show the expected delivery time on the product page.
If your order includes items with different dispatch times we will normally wait and send everything together once all items are in stock. If one of the items is going to take a while we will give you the choice either wait for everything to arrive or let us send the available items now and deliver the rest later. It is up to you.
We use trusted delivery partners to make sure your order gets to you safely and on time. We use DPD for next working day deliveries and Royal Mail for the 2 day option.
