Smart Auto Storage Discharge

Spektrum Smart Trail Pro Series batteries practically take care of themselves. Trail 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.

Smart Battery Technology

When connected to a Spektrum™ Smart charger, a Smart Trail Pro battery's unique parameters, health, and balancing information upload automatically from its memory microchip through the IC2® or IC3® connector's data wire. To charge and balance the pack, you simply connect it to your Smart charger. Safe charging begins automatically.

Simple and Quick

Preset charge, discharge, and storage parameters are automatically relayed from your Spektrum™ Smart Trail 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.

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 the trails.

New Case Design

The new case design is a thinner poly-carbonate material that allows for more mAh to be squeezed into a crawler-ready form factor.
