Product Description:
The Delipow DLP-322 is a specialized 2-slot smart charger engineered specifically for 3.2V LiFePO4 (Lithium Iron Phosphate) batteries. Featuring a modern USB Type-C input (DC 5V 2A) and a robust 600mA×2 independent charging output, it delivers safe, fast, and intelligent power replenishment for your high-performance batteries.
Equipped with an intuitive Red-to-Green LED indicator system, the DLP-322 keeps you fully informed. Red means active charging, Green means fully charged. Its spring-loaded, telescopic sliding design offers exceptional compatibility, supporting a wide range of cylindrical 3.2V LiFePO4 batteries, including 26650, 18650, 21700, 18500, 14500, 10440, and many more. Built-in reverse polarity protection ensures the charger safely turns off its indicator light to prevent short circuits if the battery is inserted incorrectly.

Frequently Asked Questions (FAQ):
Q1: Can I use this charger for standard 3.7V lithium-ion batteries?
A1: No. The DLP-322 is specifically designed and optimized for 3.2V LiFePO4 batteries with a 3.6V cut-off voltage. It is not suitable for 3.7V/4.2V lithium-ion batteries. Using it with incompatible batteries can result in undercharging or unsafe conditions.
Q2: Can I charge two different-sized batteries at the same time?
A2: Yes! The DLP-322 features two independent channels with telescopic sliding contacts. You can freely mix and match any two compatible 3.2V LiFePO4 battery sizes from the supported list without any issues.
Q3: How do I know when the battery is fully charged?
A3: It is very simple. Each channel has a dedicated LED light. While charging, it glows Red. Once the battery reaches the precise 3.6V±0.1V cut-off voltage, the light automatically turns Green, indicating it is ready for use.
Q4: How long does it take to fully charge a 26650 4000mAh battery?
A4: With a stable 600mA×2 output, it typically takes approximately 7 to 8 hours to fully charge a high-capacity 4000mAh 26650 battery. Charging time varies depending on the battery's specific capacity.
Q5: What happens if I insert a battery in the wrong direction?
A5: The DLP-322 is equipped with smart reverse polarity protection. If a battery is inserted incorrectly (reversed positive and negative), the LED indicator will automatically turn off, preventing any electrical short circuits and protecting both the charger and the battery.
