No voltage sag when you rip it

Unlike cheap packs that choke under load, these original Samsung 21700 cells hold steady voltage. Your motor gets the full juice even when climbing steep fire roads or launching from a dead stop.

Real-time diagnostics on your phone

The original JBD Smart BMS monitors temperature, balance, and individual cell state. Fire up the official app to dial in settings and check your remaining capacity with 100% precision.

Powder-coated steel enclosure

Ditch the soft heat-shrink PVC wrap. This heavy powder-coated steel chassis acts as armor against flying rocks, road vibration, and those accidental garage tips that would puncture other packs.

Got Questions? We Have Honest Answers.

How do I know these Samsung 21700 cells aren't cheap fakes or B-grade?
We get the skepticism—the e-bike battery market is flooded with rewrapped fake cells. We use only brand-new, genuine Samsung INR21700-50G cells. You can easily verify this: connect to your JBD Smart app, check the cell voltage consistency, and feel the difference on your first steep climb. Genuine Samsung cells won't suffer from sudden voltage sag when you rip the throttle.
What if this metal case battery doesn't fit my scooter compartment or custom frame?
Measure twice, buy once. The solid steel metal case is exactly 290 × 195 × 95 mm (11.42 × 7.68 × 3.74 in). Unlike plastic-wrapped packs, this steel shell has absolutely zero flex and won't squeeze into a tight deck. If you are unsure about compartment clearance or need custom output wire orientations to fit your controller, reach out before ordering so we can confirm compatibility.
Will the JBD BMS randomly cut power when I’m pushing my motor hard?
Only if you exceed the physical safety limit of your selected board. If you run a 30A BMS on a 2000W motor setup, yes, it will trip to save the cells from overheating. That’s why we offer a 50A continuous discharge option for high-power electric vehicles. Our original JBD Smart Bluetooth BMS lets you monitor amp draw live on your phone, so you'll know exactly how close you are to the safety ceiling.
How do you handle the 2-year warranty if the battery is shipped directly from China?
We ship directly from our factory in China, and we stand behind our builds 100%. Shipping a 7kg lithium battery back internationally is a massive, costly hassle for you. If something goes wrong, we won't make you ship it back. We will diagnose the issue with you online via app data. If it's a BMS issue or basic component fault, we will ship you the original replacement parts from our factory and guide you through the process step-by-step. Honest, direct support—straight from the engineers who built your pack.
