Description
xMeet Power Queen’s 14.6V 20A LiFePO4 battery charger, a purpose-built solution for 12.8V LiFePO4 packs. Its 2-stage CC/CV charging algorithm keeps voltage and current in balance, while a dedicated Pre-Charge function gently awakens batteries reading down to 0V. LED indicators provide at-a-glance status so you know when the pack is ready.
Smart, efficient LiFePO4 charging
With a constant current of 20A and a target around 14.6V, this charger is well suited for LiFePO4 packs 20Ah and larger. In typical use, a 100Ah pack can reach full charge in about 5 hours under ideal conditions, dramatically reducing downtime compared with slower multi-chargers.
- High-current capability reduces charge time for larger packs
- Precise CC/CV stages protect the battery chemistry
- 0V charging restores deeply discharged cells without manual intervention
Safety, protection, and durability
Multiple safeguards guard both charger and battery: over-temperature protection, short-circuit protection, reverse polarity protection, and over-voltage protection. The unit uses an aluminum alloy housing with surface oxidation and a built-in cooling fan to dissipate heat, helping maintain safe operation during use.
- Aluminum housing with cooling fan for reliable operation
- Protection against common faults to extend life
- Compact, rugged design suitable for shop or garage use
Designed for 12V LiFePO4 energy systems
Specifically built for 12V (12.8V nominal) LiFePO4 batteries, the charger supports 0V activation to reactivate a fully depleted pack and returns to a safe, balanced charge.
