A 50A charger for big 12V lithium house banks. The Epoch 12V 50A Marine & RV Lithium Battery Charger refills large 12V LiFePO4 banks fast: about 50Ah every hour during bulk charging. It plugs into a 120V AC outlet or a properly sized generator, connects with ring terminals, and runs at up to 95% efficiency. The IP67 aluminum housing doubles as a heatsink and is built for RV, marine and mobile use.

🔧 Will It Work With Your Battery Bank?

A high-output 12V LiFePO4 charger with ring-terminal output. Epoch lists it for:

RV house banks
Marine house banks
Van life builds
Off-grid 12V banks
Shore-power top-offs
Generator charging

📏 Quick check before you order:

Your battery or bank is 12V LiFePO4. It is not for AGM, flooded, gel, SLA or car starting batteries, or for 24V, 36V, 48V or 72V systems.
Your battery or bank can accept at least 50A of charge current. Check the battery's max charge current before you order. Smaller single batteries often need a lower-amp charger like our 12V 15A.
You have a 120V AC outlet, or a generator that puts out stable 120V AC and is sized for the load.
Your battery has terminals that accept the charger's ring terminals.

Not sure? Tell us what you're powering and we'll help you size it before you buy.

Why Go With 50 Amps

⚡

Fast Bulk Charging

About 50Ah per hour. A 200Ah bank takes about 4 hours from empty, before tapering.

⛽

Less Generator Runtime

Puts more charge back per hour than small converters, so you can run your generator for less time.

🔋

Built for LiFePO4

A charge profile made for 12V lithium iron phosphate batteries, not lead-acid.

💧

IP67 Rated

Dust-tight and protected against temporary immersion up to 1 m for 30 minutes. Not rated for water jets or pressure washing.

🛡️

Seven Protections

Overtemperature, ambient temperature, reverse polarity, overcharge, output overvoltage, output overcurrent and output short-circuit.

🧱

Rugged Aluminum Housing

The aluminum alloy case acts as a heatsink, rated from -40°C to 60°C, with a shock-resistant build for RV, marine and mobile use.

⏱️ How Long Does a Charge Take?

Battery bank	Approx. bulk time from empty
12V 100Ah	About 2 hours
12V 200Ah	About 4 hours
12V 300Ah	About 6 hours
12V 460Ah	About 9.2 hours
Other sizes	Bank Ah ÷ 50 = hours

Epoch's estimates before tapering and any BMS charge-current limits. A battery that isn't empty finishes sooner.

🔌 Charging Made Simple

🔗

Ring Terminal Connection

Attach the ring terminals to your battery or bank, positive to positive and negative to negative. Reverse polarity protection is built in.

🔌

Shore Power or Generator

Plug into 120V AC at a campsite or marina, or into a generator with stable 120V output that's sized for the load.

📏

Check Your Charge Limit

Make sure your battery or bank accepts at least 50A. Larger banks spread the current across batteries.

📦

Leaving It Connected

It has overcharge protection, but follow your battery maker's storage and long-term guidance at the marina or campsite.

❓ Common Questions

How fast will it recharge my RV or boat battery bank?

About 50Ah per hour during bulk charging. Divide your bank's amp-hours by 50 for a rough time from empty, before tapering and BMS limits.

Can I run it from a portable RV generator?

Yes, if the generator puts out stable 120V AC and is sized for the load. It can cut generator runtime compared with small converters.

Is 50A safe for my lithium battery?

Yes, if your battery or bank accepts at least 50A of charge current. Check its max charge current first.

Will it overcharge my batteries if I leave it connected?

It has overcharge protection, but follow your battery maker's storage and long-term guidance.

Will it wake up a fully depleted lithium battery?

Epoch doesn't list a 0V wake-up feature. Follow your battery's manual or give us a call first.

Can I use it on AGM or lead-acid batteries?

No. It's for 12V LiFePO4 batteries only unless the battery maker confirms compatibility.

Can I use it on a 24V or 36V trolling motor system?

No. It's a 12V charger only. Epoch makes separate 24V and 36V chargers.

What's the warranty?

Epoch covers its chargers for 2 years from the original purchase date. Register within 90 days or keep your proof of purchase.
