Spektrum Smart G2 Trail Pro LiPo Battery Overview
Spektrum Smart Technology is proud to introduce our lineup of Smart Trail Pro LiPo batteries designed to provide consistently higher voltage throughout the entire run of the battery under even the most extreme amperage loads.
Developed specifically for RC scalers and crawlers wanting maximum capacity and power, the new Spektrum Smart Trail Pro Series batteries deliver! The Pro series batteries allow for more capacity to be squeezed into the LiPo cells, allowing for larger mAh ratings when compared to similarly sized battery packs. The Trail Pro Series features a newly designed semi-hard case shell that is thinner and more lightweight, all the while staying rigid, durable, and impact resistant. In addition, the thinner case allows us to pack more mAh and higher C rated cells into limited spaces. This series lives alongside current Smart G1 and G2 batteries and is an upgrade to standard hardcase surface packs.
The Smart Trail Pro Series battery's benefits include longer battery life, better performance over the pack's life, and the peace of mind that comes from knowing your Smart battery is maintenance-free.
When a Smart Trail Pro Series 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 Trail Pro Series surface batteries store a wide variety of essential information, including:
- Battery Brand
- Battery Type
- Battery Capacity
- Battery C Rating
- Individual Cell Voltage
- Battery Temperature
- Charge/Discharge Cycles
Spektrum Smart Trail Pro Series surface batteries also maintain an error log, including incidents of overheating, over-discharge, and overcharging. This data can help ensure that the battery you've chosen is suitable for the application.
