Eunorau Dual Battery Parallel Connector Review

A small connector rather than a battery, the Dual Battery Parallel Connector is priced at $59. Its store title lists 24V/36V/48V/52V/60V, while the three-line specification gives a dual battery converter rating of MAX 72V 40AH*2, an 80mm wire that includes an XT60 end, and a size of 51mm x 40mm x 12mm in black.

Specifications

Options and pricing

There is one variant, Default Title, at $59, and it was in stock when the page was read. The page shows no crossed-out price and offers no choice of voltage, wire length or color; black and the 80mm wire are simply part of the specification. It does not list what else is in the box.

How it compares

The page names no battery or bike that the connector pairs with, so none of the store's batteries can be matched to it from the listing. For price context, the Eunorau Thermal Down-Tube Battery Wrap is $69, the Eunorau 48V 5Ah Secondary E-Bike Battery with Type-C Port is $219 and the Eunorau FAT-HD Battery 15.6Ah is $399, against $59 here.

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. 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 covers original Eunorau parts and components for 24 months (manufacturing defects only, no labor) but excludes wear items, free gifts and accessories that came with a purchase, and damage from unapproved accessories or chargers; it does not name this item, so ask support whether and how it applies. It is for the original purchaser and excludes shipping damage. 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 5 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.
