Starting Power Battery Features

The monolithic 12V batteries consist of finely balanced cells with identical performance and do not include any PCM (electronics) internally. The battery must be managed and operated as a single monolithic 12V block.

Key Operating Parameters:

  • Nominal voltage: 12V
  • Operational voltage: 11.5V - 15V
  • Maximum charging voltage (initial): 15V
  • Recommended subsequent charging: 14.6V
  • Minimum voltage: 11V
  • Maximum discharge current: 3C continuously for max 30 minutes from full charge
  • Operating temperature: -25°C to 80°C (discharging)

Note: We do not recommend operation in serial connection. For higher voltage systems (24V/36V/48V+), we recommend using single 40Ah cells with BMS123Smart.

Why Choose LiFePO4 Over Lead Acid
  • 10x Longer Lifespan: Dramatically reduces the need for battery changes compared to traditional lead acid batteries
  • Faster Recharging: Operates with much lower resistance for quicker recharge times
  • Lightweight Design: Approximately 1/4 lighter than lead acid batteries
  • Higher Capacity: Provides twice the battery capacity in the same space
  • Wide Temperature Range: Operates from -40°F to 158°F, handling far wider temperature variations
