58.4V LiFePO4 Charger for 48V and 51.2V Battery Systems
The LINIOTECH 58.4V 20A LiFePO4 battery charger is built for 48V and 51.2V lithium iron phosphate batteries with 16 cells in series (16S). It delivers up to 58.4V DC at 20A from a standard 110V AC wall outlet. That means you can fully charge large LiFePO4 batteries for solar storage, RVs, golf carts and marine systems at home, in the shop or on the road.
Many “48V” chargers on the market are built for lead-acid or other lithium chemistries. As a result, they never bring a LiFePO4 battery to a true full charge, or they push the wrong voltage altogether. This charger is different. Its 58.4V output matches the exact full-charge voltage of a 16S LiFePO4 pack, so your battery reaches 100% without guesswork.
Key Features
58.4V Output Matched to 16S LiFePO4
A LiFePO4 cell reaches full charge at 3.65V, and 16 cells × 3.65V = 58.4V. This charger’s output matches that target, so it suits 51.2V nominal (often labeled 48V) LiFePO4 batteries.
20A Fast Charging
At 20A, the charger refills a 100Ah 48V battery in roughly 5 to 6 hours. For larger banks, it still delivers a full overnight charge on most single-battery systems.
Live Voltage and Current Display
The front-panel digital display shows charging voltage and current in real time. So you can watch the battery fill up, spot a problem early and see when charging current tapers off near full.
Aluminum Housing With Active Fan Cooling
A rugged aluminum case with ventilation slots and a built-in cooling fan moves heat away during long charging sessions. That keeps performance steady even at full 20A output.
Color-Coded Alligator Clamps
Heavy red (+) and black (–) alligator clamps connect quickly to battery terminals and bus bars. There’s no special connector required.
Is This 58.4V Charger Right for Your Battery?
Before you connect any charger, check your battery’s label or datasheet. This charger is the right match when your battery is:
- LiFePO4 chemistry (lithium iron phosphate)
- 16S configuration, with a 51.2V nominal voltage (often sold as “48V”)
- Rated for a 58.4V charge voltage (some manufacturers specify 56–58.4V)
- Rated for 20A or more charging current, as allowed by its BMS
Don’t use it on lead-acid batteries, on 48V NMC lithium batteries (13S, 54.6V full charge) or on 15S LiFePO4 packs (54.75V full charge). In each case, 58.4V would exceed the battery’s safe charging voltage.
How Long Does It Take to Charge?
To estimate charging time, divide the battery’s amp-hour (Ah) capacity by 20A, then add about 10% for the final top-off stage.
| Battery capacity (51.2V) | Approximate charge time (empty to full) |
|---|---|
| 50Ah | 2.5–3 hours |
| 100Ah | 5–5.5 hours |
| 200Ah | 10–11 hours |
| 280Ah | 14–15 hours |
| 314Ah | 16–17 hours |
As a rule of thumb, 20A suits batteries of about 50Ah and larger. For a 100Ah battery, it equals a gentle 0.2C charge rate, which helps extend battery life.
Where to Use This 58.4V LiFePO4 Battery Charger
- Solar energy storage: charge 48V server-rack and wall batteries during setup, commissioning or long periods without sun.
- Golf carts and utility vehicles: charge 51.2V LiFePO4 upgrades that need a lithium-specific charger.
- RVs and camper vans: top up a 48V house battery from shore power.
- Marine systems: charge 48V trolling-motor and onboard power batteries.
- Backup power systems: keep standby LiFePO4 batteries ready between outages.
If you’re building a 48V system, this charger pairs well with the Liniotech LifePower4 5.12kWh 51.2V 100Ah battery and the Liniotech 10kWh 48V 200Ah Power Brick, provided each battery’s charging specifications allow 58.4V and 20A.

How to Connect and Charge Safely
- Confirm your battery is a 16S LiFePO4 pack rated for 58.4V charging.
- Place the charger on a flat, dry surface with space around the fan and vents.
- Connect the red clamp to battery positive (+) and the black clamp to battery negative (–).
- Plug the charger into a 110V AC outlet.
- Watch the display. Current stays high during the main charge stage, then tapers off as voltage approaches 58.4V.
- When charging is complete, unplug the charger from the wall first, then remove the clamps.

Frequently Asked Questions
What is a 58.4V LiFePO4 charger used for?
A 58.4V LiFePO4 charger charges 16S lithium iron phosphate batteries, which have a 51.2V nominal voltage and are often sold as 48V batteries. The 58.4V output equals 16 cells × 3.65V, the full-charge voltage of LiFePO4 cells.
Can I use this charger on a 48V battery?
Yes, if your 48V battery is a 16S LiFePO4 pack rated for 58.4V charging. Many 48V lithium batteries are actually 51.2V LiFePO4 packs. Always confirm the chemistry and cell count on the battery label first.
Can I use it with lead-acid batteries?
No. This charger is designed for LiFePO4 batteries only. Lead-acid batteries need a different charging profile, so use a charger made for lead-acid chemistry.
Will it work with a 48V lithium-ion (NMC) battery?
No. 48V NMC lithium-ion batteries are usually 13S packs that fully charge at 54.6V. A 58.4V charger would overcharge them.
Does it work with a 100Ah LiFePO4 battery?
Yes, as long as the battery’s BMS allows 58.4V charging and at least 20A of charge current. At 20A, a 100Ah battery charges from empty in roughly 5 to 5.5 hours.
What is the maximum charging current?
The charger delivers up to 20A of charging current at a maximum of 58.4V DC.
What AC power does it need?
It runs on standard 110V AC, 50/60Hz household power, so it plugs into any regular US wall outlet.
Which clamp goes where?
Connect the red clamp to the battery’s positive (+) terminal and the black clamp to the negative (–) terminal. Then plug the charger into the wall outlet.
Can I use it with Liniotech 48V batteries?
Yes, with Liniotech 51.2V LiFePO4 batteries whose charging specifications allow 58.4V and 20A. Check the datasheet for your specific model before charging.
What warranty does it come with?
The LINIOTECH 58.4V 20A LiFePO4 battery charger includes a 1-year warranty.
