    Benefits of Using Lithium-ion batteries:

    Using Lithium-ion battery offers many advantages over older SLA (Sealed Lead Acid) battery because of Lithium-ion battery's high energy density, small size, and low weight. A typical Lithium-ion battery may only has 1/4 of the weight and 1/2 of the size compared to same capacity traditional heavy bulky Sealed Lead Acid battery.

    Disposition of used battery

    Lithium-ion batteries are generally not considered an environmental hazard because they do not contain lithium metal. The United States government labels them as non-hazardous waste and does not oppose them being discarded together with the trash that makes up the local waste stream.

    Needs special recycling after treatment utility


    Package Contents:

    The battery comes with a AC charger and output box. The AC charger can charge the battery from any 100-240V AC power source.

    Excellent ebike battery
    By Clayon April 3, 2016
    Verified Purchase
    This is a very good product. It comes with a high quality charger, sturdy case, good mounting hardware, and excellent instructions. I installed it on my Prodeco Phantom 500W ebike and it took me over 15 miles under full throttle the first time I used it. My original Prodeco battery was not that good even though it was also rated at 11.6Ah. It's light and small enough that I mounted it on my downtube and does not interfere with the pedals or my legs. I have since put over 200 miles on my bike using this battery and it is performing well. I was leery of buying a battery this small at such a fair price and was pleasantly surprised at the quality and durability of this product. This company builds good reliable lithium batteries. Nice product. I would recommend it to anyone looking for a replacement battery or building a new ebike.


    Great for my e-trike
    By Alex Socialreject on October 12, 2016

    Awesome battery. Its high quality and performance did not disappoint. I've been using this with the Bafang BBS02 500W electric motor kit, on my Sunseeker Eco Delta SX trike. I've had the trike and motor for a year now, and initially went with one of those no name batteries someone built and wrapped in plastic, that I found on that auction site. Big mistake. It didn't even last a year, and for the past couple of months I've had to pedal around with no motor. Finally I decided to give this battery a shot. Over the past two weeks I've gone 32 miles before getting its gauge down to red. I usually run my motor at assist level 4, which is about 40%, making the other reviewers' mileage of 15 seem about right since they're running full throttle. My trike is big and heavy as I carry around a big chain to lock it, and a motorcycle trunk to carry things in, and this battery can handle it. I can't believe I get so much power from this little battery taking up little space in my trunk. My old one was nearly twice the size, with a claimed capacity of 20Ah. Really wish I had gone with this in the first place.


    Nice.

    Battery works great so far....using with a 36v 500w front hub.
    Easy to hook up

    Shipped on time. Easy to hook up. Good little battery for my e-trike. Around 15 miles per charge. All Items were in shipping.


    So far it is working well.

    Am using it on a bike with a 36v 500 watt rear hub motor. I like the compact size that fits well in a rear bike bag.
