Does what it says on the tin.

Rating: 5 out of 5 stars

Capacity as anticipated, I have somewhat tested the waterproofing :) and I've run these in parallel which gave plenty of grunt. In short, my next portable waterproof battery will be coming from Newport.

The Perfect Battery for the NK180 HD

Rating: 5 out of 5 stars

I've been using the Newport 24V 50Ah LoPRO LiFePO4 battery with my NK180 HD on my Old Town PDL 120, and it's been outstanding.

I fish mostly saltwater in bays and marshes, so having a battery I can count on is a big deal. It's compact, doesn't take up much room, and has more than enough power to keep me on the water for my trips. I never find myself worrying about running out of battery before I'm ready to head back.

I also like how lightweight it is compared to other batteries I've used. It makes loading and unloading the kayak a lot easier without sacrificing performance.

If you're looking for a dependable battery for the NK180 HD or any 24V setup, I definitely recommend the 24V 50Ah LoPRO. It's been reliable, efficient, and one of the best additions to my kayak.

Frequently Asked Questions

You know how they say there’s no such thing as a dumb question? Well, they were wrong, but here are some common not-so-dumb ones

Does the Newport LoPRO use the same BMS Software and App as my previous Newport Lithium battery?

Yes! Simply open the app, connect to the Bluetooth software and look for the serial number of the LoPRO battery to connect and manage.

Is this battery compatible with Newport Motors?

Yes, the LoPRO batteries can be used with any Lithium-compatible motor.

Is the charger included with the LoPRO? And which charger do I select for my Newport LoPRO Battery?

The LoPRO Battery Charger is NOT included with the battery. The LoPRO battery requires a specific charger that works with the Amphenol connectors.

What happens when my LoPRO battery hasn’t been used for 60 minutes?

The Newport LoPRO batteries are designed to go into a Deep Sleep mode after 60 minutes when not in use. This deep sleep mode provides a longer storage life for every Newport Battery, and acts as a safety measure to protect the internal cells to ensure optimal lifespan and performance.

To wake your Newport Battery you can do any one of the following:
-Connect the Newport App
-Connect to your charger
-Connector to a load source (ex. NK, NT or NV motor)

If the battery doesn’t wake up upon executing one of the above actions, your battery has reached a state of sleep function where it is required to receive a second “ping” or action in order to wake. To provide a second “ping” simply connect to the Newport App and connect to your battery (serial number will appear when connected) or try to repeat any one of the actions noted above more than once.

Does the Newport LoPRO require any special handling or maintenance?

No! Actually, quite the opposite! The LoPRO offers less worry and less maintenance than traditional AGM or Lithium batteries in a convenient and portable case that can be stored and stacked! Keeping the terminals clean and sand out of the connectors is the most important maintenance tip.
