PSL-BT Series Smart Lithium Batteries

The Power Sonic PSL-BT Series represents the next generation of lithium battery innovation—pairing advanced LiFePO₄ chemistry with integrated Bluetooth® connectivity and an intelligent Battery Management System (BMS). These smart batteries allow users to monitor state of charge, voltage, cycle count, and potential issues in real time through a free mobile app. The BMS balances cells and protects against overcharging, over-discharging, overheating, and short circuits, optimizing safety and extending battery life. Delivering up to 10 times more cycles than comparable lead acid batteries and weighing just 40% as much, the PSL-BT Series offers a drop-in replacement with dramatically improved performance. It delivers faster charging, lower self-discharge, and twice the power of lead acid—even under high discharge loads—while maintaining excellent energy capacity. Housed in a rugged UL94:V-0 flame-retardant ABS case, these batteries are ideal for applications requiring smart monitoring, reliability, and long-lasting power—such as mobility, solar storage, industrial equipment, and marine systems.
