Our take on the LiTime 12V 20A LiFePO4 Battery Charger

The LiTime 12V 20A charger is a dedicated AC-to-DC charger for 12V LiFePO4 batteries, pushing 20A at 14.6V through an Anderson connector. It has reverse polarity protection, a battery indicator and a 47-inch input cable, and it ships with an Anderson extension cable. It is not waterproof and has no USB ports, display or light. It is a single-purpose charger for owners of 12V lithium iron phosphate packs, not a maintainer for lead-acid or AGM batteries.

Best forOwners of 12V LiFePO4 batteries, including LiTime packsTrolling motor, RV and solar setups that use Anderson connectorsFaster top-ups than a 10A charger on 100Ah-class batteries
Pros
  • 20A output cuts charge time roughly in half versus a 10A charger
  • 14.6V output matches the standard full-charge voltage for 12V LiFePO4
  • Reverse polarity protection guards against a costly miswire
  • Anderson connector with 50A/M8 terminal suits common lithium pack wiring
  • Anderson extension cable included
  • CE and RoHS certified
Cons
  • LiFePO4 only; do not use on lead-acid, AGM or gel batteries
  • Not waterproof, so it needs shelter in marine or outdoor use
  • No display, USB ports or built-in light
  • Anderson plug only; other battery terminals need an adapter

Questions and answers

Will this charge a 100Ah LiFePO4 battery?
Yes. At 20A it takes roughly 5 hours to replace a full 100Ah from empty, plus balancing time at the top. Larger banks take proportionally longer.
Can I use it on a lead-acid or AGM battery?
No. Its 14.6V output is set for LiFePO4 and is too high for long-term lead-acid charging. Use a charger made for those chemistries.
Is it safe to leave connected?
It is a charger, not a float maintainer. For storage, charge to full and disconnect rather than leaving it on indefinitely.
Can I use it outdoors or on a boat?
Only under cover. It is not waterproof, so keep it dry in marine or outdoor setups.
What comes in the box?
The charger with its 47-inch input cable and an Anderson extension cable. No wall adapter or terminal clamps are included.
When is it cheapest?
LiTime discounts most around major sales events and on bundles with its batteries. Check the price history before buying standalone.
