High Performance 72V 20Ah Lithium Battery

When converting a standard frame to high-voltage electric power, managing total weight distribution is just as critical as raw speed. This 72V 20Ah lithium pack drops 1,440Wh of power into your system in a compact 12.13 lbs package, cutting out bulk while maintaining heavy acceleration.

The entire matrix runs on 80 genuine Samsung INR21700-50G commercial-grade cells wrapped in reinforced, vibration-resistant PVC film. It is the perfect drop-in power house for builders who need a slim footprint and clean wiring layouts.

FAQ

1. Why use a PVC wrap setup for this 72V pack instead of a heavy metal box?

For tight moped frames or narrow bicycle down-tubes, heavy metal cases just add useless dead weight and ruin your bike's handling. By packing the internal cell matrix inside a high-density reinforced PVC wrap, we shaved the weight down to just 12.13 lbs (5.5 kg). This gives you a super light, slim profile that slips perfectly into custom frame bags or narrow compartments without sacrificing your cornering feel.

2. How can I actually tell the cells inside are genuine Samsung 50G?

You don't need to rip open the protective casing to double-check our work. Once you power up your rig and pair it with the JBD smart app over Bluetooth, the diagnostics screen gives you real-time data on individual cell group voltage, balance states, and thermal sensors. Budget generic cells cannot hold a flat voltage curve under heavy throttle pins like a true commercial-grade Samsung matrix does.

3. This pack is quite long (485mm). Any specific tips for mounting it securely?

Yes, the 485 × 100 × 75 mm layout is intentionally designed long and slim to line up nicely along motorcycle center rails or inside custom frame triangles. Because it's a PVC-wrapped pack, you should never let it rub directly against bare metal frame corners or sharp bolt heads under heavy track vibrations. We highly recommend using thick foam padding or a heavy-duty custom battery bag to lock it down tight so it doesn't bounce around during trail jumps.

4. Is the PVC wrap waterproof? Can I ride this battery pack in heavy rain?

The pack is sealed tight against daily splashes, mud, and light drizzle. However, because it lacks a gasket-sealed metal housing, you should never submerge it or leave it completely exposed to a heavy downpour on an open frame. If your custom build is going to face wet trail conditions or muddy washdowns, make sure your outer frame box or custom battery cover is fully sealed to keep puddles from pooling around the main wire leads.
