Connecting Batteries in Series and Parallel
This battery supports expansion up to 4S4P (4 in series, 4 in parallel) for systems up to 51.2V and 400Ah. Follow these guidelines for safe and effective connections:
- Pre-charge: Ensure each battery is charged separately until its voltage is consistent before connecting all batteries.
- Identical Batteries: Use only identical batteries with the same battery capacity (Ah) and BMS.
- Same Brand: All batteries in a series or parallel configuration must be from the same brand.
- Connection Order: For parallel connections, connect positive terminals together and negative terminals together. For series connections, connect the positive terminal of one battery to the negative terminal of the next.
- Cable Sizing: Use appropriately sized cables and fuses for your system's current requirements.

Charging
The Kingboss LiFePO4 battery can be recharged up to 3 times faster than traditional lead-acid batteries. It has zero memory effect.
- Recommended Charger: Use a 14.6V 20A LiFePO4 charger.
- Charging Sources: Compatible with solar panels, alternators, and dedicated LiFePO4 chargers.
- Charging Time: Approximately 5 hours for a full charge with a 14.6V 20A charger.
- Low-Temperature Cut-Off: The Smart BMS prevents charging below 32°F (0°C) to protect the battery cells from damage.
Operating Instructions
Operating Temperature Range
The battery is engineered for stability across a wide range of temperatures:
- Discharge Temperature: -4°F to 140°F (-20°C to 60°C)
- Charge Temperature: 32°F to 104°F (0°C to 40°C)
The integrated BMS automatically cuts off charging if the temperature drops below 0°C (32°F) to prevent damage and ensures safe operation within the specified discharge range.

Battery Management System (BMS)
The upgraded 100A Smart BMS provides comprehensive protection for the battery, ensuring longevity and safety:
- Overcharge Protection: Prevents charging beyond the safe voltage limit.
- Over-discharge Protection: Prevents discharging below the safe voltage limit.
- Over-current Protection: Safeguards against excessive current draw.
- Short Circuit Protection: Automatically disconnects in case of a short circuit.
- Low-Temperature Cut-Off: Stops charging when the temperature is below 0°C (32°F).
- Thermal Runaway Prevention: LiFePO4 chemistry inherently reduces the risk of thermal runaway.
