Great Battery!

We have just used this battery with the NT300 Newport motor and a 10' Newport dinghy for a 10 day trip to Chatterbox Falls in Princess Louisa Inlet on British Columbia's west coast. We had it shipped domestic US shipping to Blaine, WA and a freight forwarder that we use brought it into Canada for $18.00 CAD. This is our normal way to import large-value shipments so we pay way less shipping, manage the brokering and pay the taxes ourselves at the airport CBSA office. First we read all the paperwork and found that the battery arrived with less charge than it should have. After checking with customer service at Newport we went on to charge and use it successfully. It is used with the NT300 and a Newport 10' dinghy as the tender package for our Tollycraft CPMY (Tollycraft 44'). We found that the battery lasted a log time, far longer than we needed it to. We spent hours on the Newport dinghy exploring the anchorage, going down the coast to waterfalls and hiking trails and ashore to the pub. The battery life or performance was never an issue. We recharged it most days, but one time we didn't bother, as it had 3/5 life left. We typically motored with it at 40% to 80% throttle and that was all we needed to get everywhere in comfort and quietly.

36V 40Ah Battery

I've been running the NK300 with the Newport 36V 40Ah battery for a few weeks now. The battery has been flawless and I have not run out of power yet.
