Folding ebikes live and die by their batteries, because the frame leaves room for one specific shell and almost nothing else. The LOCKBUS 48V 13Ah promises 624 watt-hours in that hard-to-fill slot, with a 20A BMS, a key lock, and a 54.6V 2A charger in the box at 160.99. For a folding-frame replacement pack, that is a complete parts list on paper.
When we first covered this pack in August, it had no customer reviews at all, and our advice then was to test it hard inside the return window. Two months later the record has grown to two ratings and one written line, and the listing has given up something more interesting than reviews: a model number that ties it to the same battery platform we have watched sell under other brand names all month.
The model number gives away the family
The spec table prints model FP4813R0Z69, and the manufacturer row reads Dongguan Yizhan Electronics Technology. Both names are worth knowing, because we have met them before. The LGNUO 48V 13Ah pack we rebuilt earlier this month carries model FP4813R0 and the same Dongguan Yizhan factory line, and a 48V 20Ah LZIXYM pack rebuilt earlier in October carries model FP4820R0 from the same manufacturer.
Three storefronts, one factory, one shared platform code with the capacity digit sitting right in the middle of it.
That doesn't make the LOCKBUS a bad pack, but it changes what you're shopping for.
The LGNUO 48V 13Ah sibling sells for 169.00 against this pack's 160.99, and the two shells differ: the LGNUO measures about 392 by 76 by 111 millimeters, while this one is 14.1 by 5.31 by 3.54 inches, roughly 358 by 135 by 90. Measure your frame slot before you pick between them, because the platform is the same but the footprint is not.
Where the LGNUO listing fumbled its own weight rows, printing 7.94 pounds against 3.5 kilograms, all three LOCKBUS weight figures agree at 7.58 pounds.
The 1000W bracket overruns the 20A BMS
The title sells this pack for motors from 100W to 1000W, and that top bracket is the one claim the arithmetic will not carry. A 20A BMS on 48 volts caps continuous draw at 960 watts, and that's the number the arithmetic trusts.
A 1000W motor pulls about 21 amps at full load, which is over the limit, and a BMS that trips under a long climb is not a fault, it is the protection doing its job. The honest reading is that the 800W bracket works, at about 17 amps, and anything at 500W or below runs with room to spare at roughly 10 amps.
This is the same pattern we found on the LGNUO sibling, whose 30A BMS sat thin against its own big motor claims, and on pack after pack in this tier.
Listings write the motor bracket from marketing and the BMS from the bill of materials, and the two never meet. If your folding bike is a 350W or 500W machine, this pack fits its electrical reality. If it is a genuine 1000W build, the 20A board will cap what you can draw no matter what the title says.
The record is one line, and it grew by one line
Our first article said the LOCKBUS had zero customer reviews and built its advice on testing inside the return window. Today the page shows two global ratings, both five stars, and exactly one written review, from early September: the price is right, and it fits my bike perfectly. The text carries no purchase badge, nobody has voted on it, and the second rating says nothing at all.
That's a thin record, but it isn't the thinnest we've rebuilt, and the one line does carry two facts a buyer wants. One buyer has reported the price matched expectations, and one buyer has reported the pack fit their bike, though they named no model, so the fitment claim stays generic.
A 100 percent five-star score on two ratings is close to no information, and one unverified line is not a track record. The old advice stands, just with slightly more company: charge it, mount it, ride it, and confirm the range inside the return window.
What ships in the box, and what the charger math says
The package list is complete for once: the battery, a holder, a 54.6V 2A charger and two keys, with the charger spelled ch-arger in the listing's own bullet, the same template typo we found on another pack this month.
The 54.6V figure is correct 13S math, 13 cells times 4.2V, so the charger matches the pack's claimed 48V chemistry, unlike the 52V Vatoso pack we rebuilt this week whose charger voltage argues with its own title. At 2A into 13 amp-hours, a full charge from empty takes at least six and a half hours, and an overnight charge is the realistic plan.
The security lock is the feature the folding category actually needs. A locked pack fixed to the frame resists the walk-up theft that takes unlocked batteries off racks and train platforms, and it also stops the rattling-release problem on rough pavement.
The case carries no IP rating, so treat water resistance as unknown rather than assume the folding shell is sealed, and keep the pack out of heavy rain when you can.
Value next to its own family
At 160.99 for 624 watt-hours you pay about 26 cents per watt-hour, which sits near the middle of the 301 packs we track, and our data row agrees.
The LGNUO sibling asks 169.00 for the same measured platform against this pack's 160.99. The more interesting comparison is the 48V 20Ah pack from the same factory, which sells near 209 for 960 watt-hours, about 22 cents per watt-hour with roughly half again the energy, and that is the better buy per watt-hour if your frame has room for it.
The LOCKBUS earns its place only where the folding shell is the constraint, which is exactly the buyer the title aims at.
Range planning needs no promises from the listing, because the method is the same for every pack. E-bikes usually manage 25 to 75 miles per charge depending on the power level you ride at (Wikipedia, E-bike), so take whatever range your current battery really delivers and multiply by the ratio between its watt-hours and 624.
Replacing a smaller worn pack with this one adds about half again your familiar range, and heavy throttle riding trims that number hard. Cycle life runs 400 to 1,200 cycles to the 80 percent convention across lithium-ion chemistry (Wikipedia, Lithium-ion battery), and the listing claims no cycle count, so treat the top of that band as unproven here.
The warranty row covers one year, which is a normal term for this tier, on top of Amazon's 30-day return window. See where the price sits today against the field in our ebike battery comparison table.
Frequently asked questions
Will this fit my folding ebike?
Measure your current battery first. The pack is 14.1 by 5.31 by 3.54 inches, and the holder mounts it to the frame, so the slot needs to accept both. Confirm your bike runs 48V and that the connector on your controller matches, or budget for an adapter.
Can I run it on a 1000W motor?
Not at full load. The 20A BMS caps continuous draw at 960 watts, and a 1000W motor wants about 21 amps. The 800W bracket and below are the honest targets, and a 500W machine runs comfortably inside the limit.
How long does charging take?
At the included 2A charger, at least six and a half hours from empty, plus the taper at the top. Overnight charging is the realistic routine, and the listing offers no faster charger option.
Is the record trustworthy?
Two ratings and one written line is nearly no record, and the one text carries no purchase badge. It reports a fair price and a good fit and nothing else. Buy this pack on its specs and the return window, not on its reviews.
How does it compare to the LGNUO 48V 13Ah?
Same factory platform, same 624Wh, a small gap between 160.99 and 169.00. The shells differ in footprint and the LGNUO listing carries its own weight-row conflict, so the choice comes down to which shell fits your frame slot and which listing you trust more.
