    • Working after a hiccup!
Edit, got ahold of the vendor - they were helpful and responsive. Issue was resolved with a replacement battery and its working as expected Battery meter not working, tested real capacity lower than advertised, no support! Really disappointed unfortunately

    • Large capacity lightweight, shipping takes 5 weeks.
Product does what it says. Its the typical one you see under many names. Seriously doubt you'll be able to warranty it if fails after return window. Shipping took over a month. No charger. Cruised around on my powered paddle board without issue. Barely used any power.

    • Great quality
Great size and battery life. Trolling for a half day (35lb thrust) didn't even put a dent in the charge.

    • IMPRESSIVE
I went fishing for 4+ hours and the battery power was still going strong on the way back. This lithium battery is way better than your usual battery. It's light enough to be carried like a briefcase. I am impressed.

    • Lots of connections, needs more durable seal and indicator.
Upper seal is not 100% reliable in outdoor use. Installing a digital %used meter does not do very much good if the manual states "it doesn't read correctly.". The tiny fragile pushbutton on the digital display is a very quick failure point. Why not a larger button with more tactile feel?

    • Great!
I bought this WannaPow 120ah battery for my canoe. It was shipped and delivered very quickly and in great condition: briefcase design, light weight and perfectly sized.
