Eunorau SPECTER E-Bike Replacement Battery Review

The page says this 48V battery fits the SPECTER-S and SPECTER-ST and uses original SAMSUNG 35E cells. It is offered as 14AH at $499 and 17AH at $599, and its table lists aluminum 6061/PC+ABS as the material, Model No SSE-103, a 13S5P configuration and a Dual-DC2.1 charging port, with figures given only for the 17AH version.

Specifications

Options and pricing

The Battery selector has two entries: 48V 14AH at $499, which was out of stock when the page was read, and 48V 17AH at $599, which was in stock, so the From $499 starting price belongs to the option that was out of stock. The page shows neither a crossed-out price nor a color choice, and a charger is not mentioned.

How it compares

The Eunorau Meta / Defender / HS Bike Battery and the Eunorau NEW-TRIKE / ONE-TRIKE Battery also start from $499 but are named for other bikes. The Eunorau Universal 48V 15Ah Secondary Battery is $499 for 15Ah, whereas this page offers 14AH at $499 and 17AH at $599.

Shipping, returns and warranty

Shipping: the shipping page says accessories and batteries go by FedEx or UPS in an estimated 5 to 9 days after 1 to 3 business days of processing; orders over $100 ship free and smaller orders pay $14.99, with a possible remote-area charge. If the local warehouse is out of stock, the item ships from an overseas warehouse in an estimated 10 to 15 business days, and there may be no carrier tracking until it reaches the destination country and clears customs. The FAQ gives 15 to 20 days for batteries sent from China. Returns: an order can be cancelled for a full refund before it ships or is produced, but not after it ships; the page asks buyers not to refuse a delivered e-bike and to contact the store instead. A return must be applied for within 7 calendar days of receipt, the product must be new and re-sellable (not assembled, ridden, used or damaged) and complete with its manuals, accessories and original packaging, and the buyer ships it back within 7 days at their own cost to Eunorau's warehouses in the US, Australia, Europe or the UK. The store inspects it within 5 days and refunds in full when the fault is Eunorau's (wrong, damaged or defective item) or minus the shipping cost when the reason is the customer's. The terms page says customers are charged shipping only once, returns included, with no restocking fee, which does not match the return page's wording. Warranty: the warranty page lists 24 months for the battery, covering manufacturing defects only; it is void if the battery's seals are broken, if the wrong or a misused charger was used, or if the battery was used in equipment other than the bike it is specified for. It is for the original purchaser, excludes shipping damage (report it at once with photos or video) and does not cover labor. Disputes under the warranty go to binding individual arbitration (AAA rules, Nevada law) unless the buyer emails an opt-out within 30 days of purchase.

Before you buy

The page shows 2 customer reviews with 100% of them five-star in the store's own widget, which we could not verify; several product pages show the same review counts or lists, so the figure may not belong to this item alone. Reputation: Eunorau E-Mobility USA Corp has an F grade on the Better Business Bureau, is not BBB accredited and has 2 complaints on file, both marked unanswered: a December 2025 request for proof that a bike sold as new was new, and a May 2025 report of a battery cover that would not latch, which the buyer attributes to a frame defect. A web search on 21 October 2026 found no Trustpilot page for Eunorau. The store says it has specialised in e-bikes since 2009 and designs its bikes in the US and manufactures them in Shanghai, while the BBB lists a business start date of 12 December 2019; the eunorau-ebike.com domain was registered on 27 July 2016.
