What defines compatibility for an integrated eBike battery (in-frame / down-tube)?

Compatibility is mainly determined by the battery case type and mounting interface, including rail/slide structure, locking position, connector location, and overall dimensions. For integrated batteries, even a small difference in connector angle or lock geometry can affect fitment, so a drawing or sample reference is recommended before quoting.

What specs do you need to quote an integrated eBike battery correctly?

To quote accurately, the key inputs are voltage system (36V/48V/52V), target energy (Wh), continuous/peak discharge current, and any special requirements such as communication (UART/CAN/SMBus), fuel gauge or display, charger spec, and connector type. If the battery must match an existing bike frame, case drawings or an original sample are strongly recommended.

How do you confirm the fitment if the customer only has photos (no drawing)?

Photos can be used for a first check, but final confirmation requires at least key dimensions, mounting rail/lock details, and connector position. For integrated batteries, the safest method is sample matching or providing a 3D scan or reference model to avoid fitment issues during assembly.

What is the MOQ for integrated eBike batteries with an existing housing vs. a new housing?

MOQ depends on whether the project uses an existing proven housing or needs a new case/tooling. Existing housings usually allow a lower MOQ, while new housings require tooling and verification, so MOQ is higher. MOQ is also affected by cell choice, BMS features, and label/packaging customization.

What is the typical lead time for integrated eBike battery sampling and mass production?

Lead time is driven by whether the housing and BMS solution are standard or customized. Typical workflow is spec confirmation, prototype build, functional/fitment check, sample approval, then mass production. Lead time may extend if there is communication debugging, case modification, or cell supply changes after the sample stage.

What QC tests are recommended for integrated eBike batteries before shipment?

QC for integrated eBike batteries should cover both electrical performance and mechanical safety. Typical checks include capacity/aging test, BMS protection verification, charge/discharge function, connector and lock reliability, and basic vibration/handling checks to reduce assembly-line failures and after-sales issues.

Triangle Battery for Electric Bikes

Triangle eBike batteries are widely used on city e-bikes, commuting bikes, and mid-drive systems because of their stable frame fit and balanced weight distribution.
At Junda Battery, triangle battery packs can be customized by voltage, capacity, cell brand, BMS functions, and connectors, with full support for OEM integration and replacement supply.
Your project can be supported from prototyping to mass production, including labeling, wiring harness, and export-ready shipping documents.

Built for high-power setups (up to 5000W motor support)

Designed for high discharge performance, our triangle eBike battery packs can be configured for powerful eBike conversions and heavy-load riding, giving more stable output for 3000W–5000W builds.

Premium cell options: EVE & Samsung

You can choose EVE cells for cost-effective performance, or Samsung cells for higher consistency and long-term stability—ideal for Australia’s demanding riding conditions and longer commutes.

Triangle shape = better frame fit & balanced riding feel

Triangle battery design provides a more secure fit inside the bike frame, improving weight distribution and reducing “rear-heavy” handling compared with rack or seat-post batteries.

A top choice for Australia’s eBike conversion riders

Popular among Australian DIY builders and conversion workshops, triangle battery packs are preferred for their clean installation, high-power capability, and flexible customization for different motor/controller combinations.

Integrated eBike Battery

Triangle eBike Battery You Can Define

An eBike battery program stays on track when the key specs are clear from day one—voltage platform, Wh target, peak motor current, enclosure space, and charger/BMS interfaces. Defining these inputs early helps reduce fitment rework, avoid BMS cutoffs, and keep performance consistent from prototype builds to repeat orders.

18650 / 21700 Cell Supply

18650 and 21700 cells are supported with flexible sourcing options from Molicel, LG, Samsung, EVE, and DMEGC. Cell selection can be recommended based on real requirements—power demand, cycle life target, and budget—so cost stays under control without overspecifying.

50+ Models for Shops & OEM Programs

Fitment-ready pack designs cover 50+ eBike models commonly used by repair shops, distributors, and eBike factories. Housing style, mounting interface, and connector layout can be aligned to reduce installation rework and speed up replacement or upgrade programs.

100% Aging Verification

Every pack goes through 100% aging test and functional checks before shipment to reduce early failures. Global insurance coverage is provided to reinforce accountability for product quality and safety in real-world use.

Fast Lead Time with Economical Shipping Options

Fast dispatch is supported with typical lead time targets and a shipping plan chosen for cost-efficiency. Logistics options are optimized to balance delivery speed and freight cost—helping reduce both timeline pressure and landed cost.

How We Build Triangle eBike Battery

common Questions

FAQs About Triangle eBike Battery Packs

Can your triangle eBike battery support a 5000W motor?

Yes. Triangle packs can be configured for high-power eBike conversions, and the final motor support depends on the battery voltage, capacity, and BMS discharge rating. You can share your motor/controller specs and you will be recommended a suitable configuration.

Which cell brand is better for my build: EVE or Samsung?

Both options are supported. EVE is a great choice for cost-effective performance, while Samsung is preferred for buyers who want higher consistency, better long-term stability, and premium build positioning.

What voltage options are available for triangle eBike batteries?

Common triangle battery voltages include 48V / 52V / 60V / 72V, and custom voltage configurations can also be supported depending on your eBike system requirements.

How do I choose the right capacity (Ah) for my triangle battery?

Capacity depends on your riding range target, motor power, and riding style. Higher Ah means longer range, and high-power builds usually need both sufficient capacity and strong discharge performance to avoid voltage sag.

Can you customize the BMS functions for Australia eBike conversions?

Yes. Triangle packs can be customized with BMS features such as over-charge/over-discharge protection, over-current protection, temperature protection, and optional communication or display integration based on your project needs.

Is this triangle eBike battery suitable for replacement orders or small batch OEM?

Yes. Triangle packs are supported for both replacement supply and OEM projects. Labeling, wiring, connector types, and packaging can be customized, and stable production can be supported after sample approval.
