● The normal operation of the self-heating function requires a stable charge current greater than 4A for each battery in the parallel battery bank. The self-heating function will not be able to operate normally if a PWM charge controller or a small current battery charger is used to charge the battery at low temperatures.
● Please secure all cable connections to the proper specification in order to ensure good contact between the cable lugs and the terminals. Over-tightening cable connections can cause terminal breakage and loose cable connections can cause terminal meltdown or fire.
● DO NOT string the battery in series. ONLY connect batteries of the same manufacturer and model in parallel.
● Please avoid too high a voltage difference between paralleled batteries, despite the auto-balancing function, to avoid triggering the over-current protection.

Key Features

  • Connects multiple batteries in parallel safely with the auto-balancing function to meet the power and energy requirements of different system setups.
  • The battery management system (BMS) provides comprehensive protection to the battery and manages the charging and discharging process.
Uncompromised Quality
  • The state-of-the-art battery cells ensure an exceptional lifespan of more than 4000 cycles (80% DOD), up to 100A continuous discharge current, and a wide range of operating temperatures.
Communication Port
