  • [One Touch Control Battery] Power Queen OTCB Smart LiFePO4 Battery owns a One Touch Control Battery technology patent. No need to download the APP on the phone, it can more easily control the battery on/off and achieves one-touch sleep mode activation & force charging mode under low temp protection. Through One Touch Control, OTCB allows interacting with the battery, enabling intelligent one-touch managing and LED monitoring. The straightforward operation brings great convenience to the user experience.

  • [LED Indicator & SOC Reminder] The 100A BMS inside OTCB Smart LiFePO4 Battery can detect SOC at low capacity<20%(green light flashes), and reflect the battery status through the LED indicator: battery under sleep mode(light off), battery under BMS protection(orange light), BMS failure(red light flashes). So this user-friendly design keeps users informed of different battery statuses and saves extra trouble to monitor the battery by checking the APP on the phone.

  • [Low-temp Cut-off & Unique Forced Charging] The smart BMS enables the built-in low-temp protection to cut off the charging and avoid damage when charged at a temp below 32°F. If any need to charge the battery under low temp charging protection, push the button to cancel the protection and charge the battery for emergency use. Besides, the BMS has multiple functions to protect from overcharging, over-discharging, over-current, short circuit, and over-temp to achieve full life-cycle management.
