The 48V 15A charger with the special connector for Epoch Big Box golf cart batteries. Epoch's Big Box golf cart batteries use a special charging connector, so a standard ring-terminal charger won't plug in. This Epoch 48V 15A LiFePO4 charger (EP-4815C) has that connector. Use it as a spare or replacement charger for your Epoch Big Box 48V golf cart battery. Epoch says it's for Big Box batteries only, so check your connector before you order.

🛡️

❓ Common Questions

Will it fit my battery?

It fits Epoch Big Box 48V golf cart batteries that use the Big Box charging connector. Send us a photo of your battery's connector and we'll confirm before you order.

How is it different from the regular Epoch 48V 15A charger?

Both are 48V 15A LiFePO4 chargers. This one has the special Big Box connector. The regular charger (CHG-48V15A) uses ring terminals for batteries with standard terminals.

Will it work on Epoch's 36V or 72V Big Box kits?

No. It's a 48V charger only.

Can I use it on a non-Epoch battery or a battery with standard terminals?

No. Epoch says it's for Big Box batteries only. For other 48V LiFePO4 batteries, the regular Epoch 48V 15A charger is the right choice.

How long will it take to charge?

Divide your battery's amp-hours by 15. A 48V 105Ah Big Box battery takes about 7 hours from empty, plus a little top-off time.

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

No. It's for 48V LiFePO4 Big Box batteries only.

What's the warranty?

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