52V 30Ah E-Bike Battery – Samsung 50G

100% genuine Grade-A cells: Every 52V 30Ah pack is hand-assembled using exactly 84 authentic Samsung INR21700-50G cells in a 14S6P structure. We never use b-grade surplus, re-wrapped generics, or recycled cores.

You can verify individual cell resistance, real-time balancing, and consistent voltage retention straight out of the box through the JBD Bluetooth smartphone app.

No, 5A is well within safe charge limits: This 30Ah pack splits incoming current across 6 parallel cell groups (6P), meaning each Samsung 50G cell only absorbs approximately 0.83A (0.17C rate). Samsung rates these cells for up to 0.5C charging.

The included 58.8V 5A charger finishes a full empty-to-full top-off in about 6 to 7 hours without producing excess heat or degrading cycle health.

Match your controller's continuous draw: For standard 750W to 1,200W hub or mid-drive motors, pick the 30A BMS. For 1,500W setups (like Bafang Ultra/BBSHD with unlocked limits), go with the 40A BMS.

If you run high-output 2,000W to 2,500W controllers or aggressive hill-climb bikes, choose 50A or 60A to eliminate sudden BMS cut-offs under peak throttle.

Complete phone diagnostics: Download the free companion app (iOS & Android) to monitor individual series cell balance, internal temperature probes, cycle count, and precise percentage remaining.

You can also remotely toggle the discharge port on or off directly on your screen, functioning as an extra anti-theft security switch when parking.

Sealed against road spray: The pack is insulated internally with structural epoxy boards to isolate all cell terminals, then sealed in heavy-duty PVC wrap with injected waterproof silicone glue along the top and bottom wire exits.

It comfortably handles regular road puddle splashes and light rain. Never submerge the battery in deep standing water or wash it with high-pressure sprayers.

Fresh manufacturing: We assemble each 52V 30Ah battery upon order to ensure you receive fresh, brand-new cell batches rather than old inventory that sat on warehouse shelves losing charge.

Because packs are custom-configured for individual DIY builds, individual units do not carry universal stickers. Full testing documentation and official compliance (UN38.3, CE, MSDS) are provided for commercial and fleet batch orders upon request.

Real factory coverage: Our 2-year warranty covers internal BMS hardware faults, cell pack failure, unexpected voltage collapse, and charger defects under normal riding conditions.

If you experience any issues, send your order details and a screenshot of the JBD app battery status to our support team. We ship replacement parts or resolve pack issues directly without runarounds.
