Compact LFP Power for Everyday Light

6.4V LiFePO4 energy for bedside, study and small cordless lamps designed around repeat daily

🔋 Built for Lamps That Stay Useful Day After Day

Not every bedside or study lamp needs maximum output. Some products need a compact rechargeable source that can be used repeatedly without turning the battery into an oversized part of the enclosure. This design uses two 18500 LiFePO4 cylindrical cells in a side-by-side 2S1P arrangement, targeting 6.4V nominal voltage, 1000mAh capacity and 6.40Wh nominal energy. The target pack size is about 52 x 38 x 20 mm. PVC heat-shrink keeps the pack compact, while the final mechanical envelope is confirmed around the actual cell diameter, insulation, protection board and cable route.

🧪 LFP Chemistry Requires Its Own Charging Strategy

LiFePO4 should not be charged using a charger designed for conventional 3.7V-class Li-ion cells. This 2S pack targets a 7.3V-class full-charge voltage and uses a protection design matched to LFP cells. During engineering evaluation, 0.5C charging and 0.2C discharge provide practical reference points, while final current limits remain tied to the selected cell specification. Validation can include capacity, DC resistance, charging behavior, protection response, short circuit, drop, vibration and temperature cycling. IEC 62133-2:2017 plus AMD1:2021 provides the main portable lithium battery safety reference, with host-lamp requirements considered separately.

Frequently Asked Questions

LFP becomes useful when the project values chemistry-specific operating behavior and long-term daily use more than maximum energy density. The right question is whether that balance fits the

What is special about a 2S LiFePO4 pack?

A 2S LFP pack has a lower nominal and full-charge voltage than a conventional 2S Li-ion pack, so the charger and protection design must match LFP chemistry.

Why use 18500 cells?

The shorter cylindrical format can help reduce battery length in compact lamp bases while keeping a familiar cylindrical construction.

Is 1000mAh suitable for all desk lamps?

No. It is positioned for low-to-mid-power lighting. Higher-output lamps should be reviewed against actual load and required runtime.

Can the NTC be included?

Yes. A 10k ohm NTC is available when the host charging system supports thermistor feedback.

Can the dimensions be customized?

Yes. Cell arrangement, pack envelope, cable exit, connector and protection-board position can be adjusted around the host enclosure.
