Sorry, this item is out of stock


Spektrum Smart Technology is proud to introduce our lineup of Smart LiPo batteries with specially formulated LiPo High Voltage Chemistry designed to provide consistently higher voltage throughout the entire run of the battery under even the most extreme amperage loads. The extremely high discharge ratings, new exclusive Pro Series LiPoHV chemistry, and Smart's added benefits are game changers for the RC racing community. The Spektrum Smart Pro-Series LiPoHV batteries are class leading LiPo cells with an innovative graphene polymer giving extremely low Internal Resistance (IR) ratings, providing optimum speed and power to the motor and ESC that pro-level racers demand while giving drivers the worry-free benefits of Spektrum Smart Technology. Available in all popular sizes and configurations for 1/10 and 1/8th scale racing models, drivers get top-of-the-line LiPo performance with the added benefits of Smart, guaranteeing successful races with each pack cycle, lap after lap, and heat after heat.

Smart Pro-Series battery's benefits include longer battery life, better performance over the life of the pack, and the peace of mind that comes from knowing your Smart battery is maintenance-free.

When a Smart Pro-Series LiHV Battery is connected to a Spektrum Smart charger, its unique charging parameters and health information are uploaded to the charger from its integrated memory microchip. You can view and set preferences through the charger, such as charge rates, so all that’s required to charge the pack is connecting it to your Smart charger. Smart technology takes care of the rest.

Spektrum Smart Pro-Series surface batteries also maintain an error log, including over-heat, over-discharge, and over-charge incidents. This data can help assure that the battery you've chosen is suitable for the application.

Innovative Spektrum Smart Pro-Series surface batteries are so easy to use that they nearly take care of themselves. Smart technology makes it easy to achieve peak battery performance, reliability, and longevity!

Smart Battery Technology

When connected to a Spektrum Smart charger, a Pro-Series Smart battery’s unique parameters, health, and balancing information upload automatically from its memory microchip through the IC3 or IC5 connector’s data wire. To charge and balance the pack, you simply connect it to your Smart charger. Safe charging begins automatically.

New Pro Series Graphene LiPoHV Chemistry

New Pro Series LiPoHV Chemistry features an innovative graphene polymer that provides a consistently higher average discharge voltage over the whole discharge curve. Class-leading low internal resistance offers racers higher current per run (supplying optimum speed/power to the motor and ESC).

New Case Design

The new case design is more compact for lower center of gravity setups, and the double-sided bullet connector allows for simpler battery placements.

Smart Auto Storage Discharge

Spektrum Smart Pro-Series batteries practically take care of themselves. Pro-Series batteries come from the factory programmed to automatically discharge to a safe storage voltage of 3.90V after 72 hours of inactivity. The results are longer battery life, better performance over the life of the pack, and peace of mind that your Smart battery comes maintenance-free. The user can change the battery's Auto Storage settings based on preferences.

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 getting your gear ready for a flight.

Simple and Quick

Preset charge, discharge, and storage parameters are automatically relayed from your Spektrum Smart Pro-Series battery to your Smart charger, making charging as simple as plugging in the pack. The charge rate of individual batteries can also be user-customized, allowing you to take full advantage of packs with faster charge ratings. The battery’s integrated microchip remembers the last charging rate you set, so these settings will automatically take effect the next time you plug it in.
