Reliable, long-lasting power for everyday devices

The NERMAK 6V 4.5Ah LiFePO4 battery delivers steady, dependable energy for a range of small to mid-size applications. Its lithium iron phosphate chemistry prioritizes safety, long life, and minimal maintenance, making it a sensible upgrade from traditional options in many scenarios. With a compact form factor and built-in protection, this battery is designed to perform quietly and reliably in the background of your daily routines.

Key features that support peace of mind

• High energy density and low self-discharge help keep power ready when you need it.
• Built-in BMS guards against overcharge, over-discharge, over-current, and short circuits.
• No memory effect, so you can top off the charge without conditioning between uses.

Outstanding cycle life and safer chemistry

Designed for heavy use, this LiFePO4 battery handles 2000+ charge/discharge cycles, far surpassing typical lead-acid lifespans. The chemistry is chosen for stability and safety, offering a calm, steady power profile with low environmental impact compared to some alternatives.

Flexible setup for growing power needs

Expand or tailor your power setup through series or parallel connections. Up to four identical cells can be linked in series to increase voltage, while parallel configurations extend capacity. A quick 3A charge supports faster replenishment, and continuous output can meet the demands of power-hungry devices (up to 5A) with a pulsed 3C capacity as needed.

Versatile and widely used

Commonly adopted for emergency lights, lanterns, signage, electronics, and security systems, the battery also suits outdoor equipment and kid-friendly projects such as ride-on cars. Its steady performance is well-suited to devices that expect reliable bursts of power and consistent standby energy.
