14.6V 20A LiFePO4 Battery Charger Test

If you’ve ever wanted to unlock the full potential of your 100Ah LiFePO4 battery without using a complicated setup, this quick test might help. In this post, I go over the 14.6V 20A LiFePO4 battery charger test using a Li Time charger to see how efficiently it delivers power and whether it meets its advertised performance.

Charging LifePo 100Ah

Testing Setup

The charger I used is the Lead Time 14.6V 20A model, built for LiFePO4 batteries. On the front panel, it features a simple LED indicator to show the charging status — red for charging, green for full, and a fault indicator if anything goes wrong. It’s compact, quiet, and straightforward, which makes it ideal for quick field charging.

I connected it to a 100Ah LiFePO4 battery that I also use to power my RC chargers in the field. The setup is simple: plug in the charger, connect the clamps, and let it ramp up.

Charging Results

Once powered, the fan speed increased slightly, and the LED light turned red to confirm charging. Using a DC amp clamp set to 40A, I measured a steady flow of 19.95 amps, right on target for a 20A charger. That’s a strong result for a compact unit like this.

At that rate, a full charge from 0% to 100% should take just under five hours, which aligns perfectly with the rated specs. This makes it efficient enough for overnight charging or daytime top-ups while out in the field.

Practical Use Tips

You can safely leave the connector attached to the battery between uses, though I prefer removing it to avoid damage while moving equipment. If you’re powering RC gear or other accessories, you can clamp directly onto the connection point when needed.

Overall, the 14.6V 20A LiFePO4 battery charger handled consistent current delivery without overheating or instability — exactly what you want in a dependable charger.

Final Thoughts

This short 14.6V 20A LiFePO4 battery charger test shows that the Lead Time model performs exactly as rated. It’s efficient, easy to use, and provides a reliable way to get your LiFePO4 batteries charged safely and quickly. For anyone running a 100Ah setup, this charger is a straightforward and dependable option that hits its full potential with no surprises.
