Description
The AECharger™ Programmable DC Power Supply & Lithium Battery Charger is a constant-voltage / constant-current (CV/CC) regulated charger designed for serious users who want full control over battery charging and power delivery.
Unlike automatic “smart” chargers that lock you into fixed profiles, the AECharger allows you to manually set voltage and current limits, making it ideal for lithium battery charging, controlled battery testing, and bench power applications. The charger automatically transitions between constant current (CC) and constant voltage (CV) modes based on load conditions.
Because charging parameters are user-defined, the AECharger works across multiple battery chemistries and voltage levels, including lithium-ion, LiFePO₄, AGM, SLA, and traditional lead-acid automotive batteries.
Key Features
- Programmable lithium battery charger — user-defined voltage and current limits
- Multi-chemistry compatibility — lithium (Li-ion, LiFePO₄), AGM & SLA, traditional lead-acid
- CV / CC intelligent regulation — automatic CC to CV switching with visual mode indicators
- Built-in protection — over-current, short-circuit, over-temperature and over-voltage safeguards
- Real-time digital monitoring — voltage, current and power on an easy-to-read front panel
- Bench power supply capability — stable DC output for electronics testing and diagnostics
- USB fast-charge port
- Active cooling — temperature-controlled internal fan
Lithium Charging Quick-Start
⚠️ Read before charging lithium batteries. Example setup for a 12V LiFePO₄ pack:
- Set voltage to the manufacturer-recommended charge voltage (e.g. 14.2–14.6V)
- Set current limit based on battery capacity (e.g. 10–20% of Ah rating)
- Connect battery with correct polarity
- Enable output
- Charger operates in CC mode, then switches to CV mode automatically
This charger does not automatically detect battery chemistry. Correct settings are the responsibility of the user.
Important Safety Notice
⚠️ This is a programmable charger, not an automatic smart charger.
- Users must set correct voltage and current limits
- Incorrect settings may damage batteries or connected equipment
- Always verify polarity before enabling output
- Recommended for users familiar with basic electrical concepts
- Always read the included manual before use
What’s Included

FAQ
Is this a lithium battery charger?
Yes. The AECharger can charge lithium batteries when configured correctly. You manually set voltage and current based on the battery manufacturer’s specifications.
Does it work with AGM and lead-acid car batteries?
Yes. It works very well for AGM, SLA, and traditional lead-acid automotive batteries.
Is this safe for beginners?
This charger is best for users with basic electrical knowledge. It is not a plug-and-play smart charger.
Does it automatically stop charging?
It transitions from constant current to constant voltage automatically, but does not automatically shut off. Monitoring is recommended.
Can I use this as a bench power supply?
Yes. It is designed to function as both a charger and a regulated DC power supply.
