1560wh of storage is about as much capacity as aftermarket 52v packs get. The LOCKBUS 52V 30Ah delivers it in a compact design, with a 40A bms and xt60 connector. You can check current pricing on Amazon to see if it fits your build.
Specs & Build Quality
LOCKBUS operates at 52v nominal (58.8v max charging). With 30ah of capacity, we have a total of 1560wh. The dimensions are 12.52 x 6.1 x 3.07 inches, and the pack weighs roughly 29.1 pounds. So this is a heavy pack, but you're carrying around a lot of energy.
Waterproof PVC is used for the exterior casing. An xt60 connector is used for the discharge outlet. Form factor is a simple rectangular box. There is no downtube mount or mounting bracket. It's designed for cargo racks, rear racks, or your own custom solution.
The charger provided is a 58.8v, 3a unit. Full recharge time is about 5-6 hours from empty. Charger is basic but functional. Standard fare for this class of product.
BMS & Safety Features
The BMS built into this pack controls overcharging, over-discharging, over-current, over-voltage, short circuits, and overheating. For a 1560wh pack, 40 amps continuous gives about 2080 watts peak. That's enough for most 1000W-2000W motors without hitting BMS limits.
A 30ah pack with a 40A BMS lets you pull about 1.3C continuously. While this seems low compared to packs with higher discharge rates, lower C-ratings provide greater safety margins, especially on steep inclines and rapid acceleration. Riders pushing hard on technical trails might hit the BMS limit on long climbs, but for most commuting, 1.3C is plenty.
Finally, the PVC water-proof outer housing is a nice addition. It's not a rigid plastic enclosure but rather an extra layer of PVC wrapped around the cell groups. Suitable for rainy and splashy conditions, but don't submerge it.
The XT60 connector is rated for 60A continuous, matching the BMS output well. If you plan to use this on a 2000W motor drawing close to 40A, the connector won't be a bottleneck. Some users on forums prefer to replace XT60s with XT90s for higher-current builds, but for 40A BMS-limited operation, the stock connector is adequate. The built-in 40A BMS is also set to trip at around 42-45A for short surges, so brief spikes during hard acceleration won't cut power.
Something else worth mentioning is the 14S configuration typical of 52V packs. Fourteen cells in series gives you that 58.8V full charge voltage, and the LOCKBUS uses standard 18650 or 21700 cells based on the form factor. Without tearing it open, it's hard to confirm the specific cell manufacturer, but the capacity (30Ah) suggests a 10S5P or similar parallel configuration of quality cells. Many budget packs use Chinese cells like Lishen or Eve, which are decent for the price.
Range & Performance
Thirty amp-hours at 52 volts equals serious range. On a typical 1500W ebike consuming about 20-25Wh per mile, you could get 60-75 miles of throttle-only operation, or even more with pedal assist. Depending on your commute, this should last a whole week between charges.
The trade-off is that this is a universal battery, not bike-specific. You'll need to figure out mounting hardware and connector adapters. The xt60 connector is widely used across e-bikes, but you still need to check compatibility with your bike's setup.
Compatibility claims cover 200W-2000W motors, which is most of the ebike market. Also listed are e-scooters, ATVs, and DIY projects. Check our battery comparison table to see how it stacks up against similar packs.
Who Is This Battery Suitable For?
For those seeking maximum range per dollar, the LOCKBUS 52V 30Ah is a great option. At roughly 21 cents per watt-hour, it's one of the cheapest ways to get over 1500 watt-hours on the market right now.
This battery suits long-distance cargo riders, commuters, and DIY builders comfortable with their own electrical connections and mounting solutions. If you know your way around ebike batteries and want the most capacity for your money, this makes sense.
Not recommended for plug-and-play types who need a drop-in replacement. No mounting bracket or bike-specific connector exists. You'll need to handle those yourself.
Another concern is the lack of customer reviews. LOCKBUS is a relatively new brand on Amazon, and zero reviews exist on this listing. The specs look good on paper, but real-world performance is unconfirmed. For comparison, brands like VEVOR and Lithium Hellas have dozens of reviews you can reference ahead of purchase, so you know what you're getting. With this one, you're the first in line.
That said, this battery fills a clear gap in the market. Most 52V packs under 25 cents per Wh top out around 20Ah. The 30Ah capacity at this price point is unusual for a name-brand listing. If the cells perform as advertised, this is genuinely one of the best value options available.
The PVC waterproof casing is worth emphasizing. A lot of budget batteries use thin ABS plastic that cracks or lets moisture in after a season of riding. The thicker PVC wrap on this unit looks more durable than the typical budget shell.
Range-wise, sixty to seventy-five miles of throttle riding translates to well over a hundred miles with moderate pedal assist. That's enough for serious long-distance touring or multi-day trips without access to charging. For daily commuters riding 10-15 miles each way, you'd charge maybe once a week. That level of convenience is hard to beat at this price.
Frequently Asked Questions
What size connector does this battery use?
An xt60 connector is included. Your bike may use a different connector, so you might need an adapter or need to modify your bike's connector.
Will this battery fit my bike?
Measurements are 12.52 x 6.1 x 3.07 inches. It's a rectangular box with no mounts. Measure your battery compartment or rear rack before buying.
How long does it take to charge?
The included 58.8V, 3A charger takes about 5-6 hours from empty.
Can I use this with a 48V controller?
Most 48V controllers handle 52V batteries fine. A 52V pack charges to 58.8V, which is within the range of most 48V controllers. But check your controller's specs to be safe.
Are all components included?
Yes, you get the battery, a 58.8V 3A charger, and an xt60 connector. No mounting bracket included.
Is this a LiFePO4 battery?
No. It's standard lithium-ion (NMC). The voltage profile (52V nominal, 58.8V max charge) corresponds to 14S lithium-ion at 4.2V per cell. Expect 500-800 cycle life, not the 1500-2000 you'd get from LiFePO4.
