Yes. KeepKnow 12V batteries support parallel connection for easy capacity expansion. For safety and best performance, always use batteries of the same model, capacity, and configuration.

12V 100Ah / 320Ah systems support up to 4S4P configuration, enabling flexible energy scaling.

Runtime depends on battery capacity and appliance power consumption. You can estimate runtime using:

Battery Capacity (Wh) ÷ Appliance Power (W) = Approximate Runtime (Hours)

For example, a 12V 100Ah battery provides about 1280Wh, while a 12V 320Ah battery provides about 4096Wh. A 500W appliance can run for approximately 2.5 hours on 100Ah or 8 hours on 320Ah under ideal conditions.

KeepKnow 12V batteries support charging via a dedicated LiFePO4 charger, solar panels with MPPT, or a gas generator.

KeepKnow batteries are FCC, CE, RoHS, UN38.3 certified and feature a built-in BMS for full protection. They are rigorously tested and have no fire risk under normal use.

When the temperature is below 32°F (0°C) during charging, the self-heating system activates using power supplied by a charger with a current output greater than 7A. Once the battery warms to 37°F (3°C), charging automatically begins. This helps prevent damage caused by low-temperature charging and ensures dependable performance even in cold environments.
