The integrated microchip stores battery parameters and health data, allowing the charger to automatically apply the correct settings. These batteries are ideal for drivers who require both performance and longevity from their power system.

What makes the Spektrum S2100 charger ideal for Smart G2 batteries?

The Spektrum O-SPMXPSS550I Smart charger and battery combo with internal balancing and LCD interface includes the S2100 Smart AC charger, which delivers 2×100W of charging power and supports a wide range of battery chemistries. Its Auto Charge feature instantly recognizes Smart battery parameters and begins safe, accurate charging without manual setup. The charger’s internal balancing system uses the same IC5® connection for both charging and balancing, eliminating the need for separate balance leads. This simplifies the charging process and ensures optimal cell performance with every cycle.

How does internal balancing improve battery safety?

The Smart G2 battery with integrated microchip and automatic storage discharge to 3.90V uses Spektrum’s advanced balancing system to maintain cell integrity during charging. Balancing data travels through the IC5® connector’s data wire, allowing the charger to monitor and adjust each cell’s voltage in real time. This reduces the risk of overcharging and extends battery life. The charger also supports programmable charge rates, giving users control over charging speed and thermal management. These features are essential for maintaining battery health in high-demand surface applications.

What safety features protect your gear?

The S2100 G2 AC Smart Charger with 2×100W output, USB firmware updates, and Auto Charge includes multiple layers of protection to safeguard both the charger and battery. Reverse polarity protection prevents damage from incorrect connections, while thermal protection maintains safe operating temperatures. Short circuit protection and a safety timer further enhance reliability, ensuring that charging sessions are secure and controlled. These systems work together to deliver a safe and dependable experience for drivers who push their vehicles to the limit.
