You need a 36V replacement pack in the Hailong case format, your frame takes the standard downtube slide, and the budget is tight. The LOCKBUS 36V 10Ah looks like the answer on the shelf: key lock, LED indicator, a USB port for a phone, and a 30A BMS behind a 1000W motor claim.
Look closer and the picture thins. The pack costs 129.99 for 360 watt-hours, which is a lot per stored unit at this end of the market. And the entire buyer record is a single text that says almost nothing.
This article is therefore two things at once. It is a review of the listing's numbers, which turn out to be the honest part.
And it is a method for buying on a record that carries no evidence, because there is no owner experience here to lean on. Our battery table holds the full market if you want the context first.
A record of one text that says nothing
The listing shows 5.0 from one rating, and the histogram is 100 percent five-star because there is nothing else to count. The one written text is purchase-badged and dated mid-October 2026. Here is its complete body, garble included: the owner had fun, wrote their bike, and had a fun anyway.
Fifteen words, and not one of them is evidence. No bike model, no range, no capacity check, no charging time, no fitment note. The star rating is real, but a 5.0 from a sample of one contentless text is presentation, not a track record.
Nothing in this record contradicts the listing, and nothing in it confirms the listing either.
That emptiness changes how you should shop. Every claim you care about has to come from the listing itself, so you verify what can be verified on paper and you test the rest on arrival. The sections below do the paper work.
The arithmetic is the honest part
Start with the power claim, because budget listings usually overshoot here and this one does not. The BMS allows 30A constant. Thirty amps at 36V gives 1080W, and the motor claim tops out at 1000W.
The claim sits inside the ceiling, which is the rare honest direction. A 750W motor draws about 21A at full tilt, comfortably inside. The card even prints a 200W floor for the motor band, which makes sense, because small draws confuse controllers more than big ones do.
The charger checks out too. The included unit is 42V at 2A, and 42V is 10 cells at 4.2V, the correct charging voltage for a 36V-class pack. The parameters card agrees on the rest of the electrical story: cut-off at 30V, operating band 30 to 42V.
Ten amp-hours at 2A takes at least five hours, and the card's 2-5A charge range says a faster charger is possible if you buy one.
The weight closes with room to spare, which puts this listing on the honest side of a question that matters on this site. Three point two kilograms for 360Wh is a heavy reading, about 113 watt hours per kilogram at pack level.
Budget soft packs print figures twice that, and some of those do not survive the arithmetic. This shell does, and the spare room suggests no inflated cell claim behind it. Wikipedia's chemistry figures put the best cells at nearly three times this pack's density (Wikipedia, lithium battery chemistries, fetched live this week), so a heavy 36V pack is normal, not suspect.
One small print catches the eye. The bullet says the pack weighs 7 pounds. The dimension card says that 7-pound figure is the gross weight, box and all.
So the bullet overstates the pack's own weight by the packaging, which is the harmless direction for a weight claim to err. Listings usually lean the other way.
Same factory, three storefronts, and a price that argues
The spec table gives the game away. Model EB-S1/FP4813R0, manufacturer Dongguan Yizhan Electronics Technology. Those two strings tie this pack to a family we have tracked across the market: the LZIXYM 13Ah carries model number FP4813R0Z69 from the same manufacturer, and the 20Ah shells sold as LOCKBUS, LGNUO, and LZIXYM share a different model number and the same factory. One platform, three brand names, many listings.
That matters for price. This 36V pack costs 129.99 for 360Wh, about 36 cents per watt-hour.
The same factory's own bigger shells run 160.99 for the 13Ah at about 26 cents, and 199 to 209 for the 20Ah USB packs at 21 to 22 cents. The LOCKBUS 48V 20Ah USB review covers the sibling, and the LZIXYM 13Ah review covers the 13Ah shell. If your frame accepts either footprint, the bigger packs are the better buys on pure arithmetic.
The counterargument is fitment. Hailong cases come in lengths, and a frame built for a short 36V shell may not take a longer 13Ah or 20Ah pack. If 360 by 90 by 109 millimeters is what your battery bay holds, this pack is not overpriced by accident, it is the right size and you pay for it. Measure the bay first, then check the current LOCKBUS price.
What you actually get in the box
The package list is complete for once: the pack, its mounting base, the 42V 2A charger, two keys, XT-60 plug wiring, and a manual. Both common connector names appear in the listing, XT60 in the bullet and T-Plug in the title, so confirm which one your controller wants before ordering rather than trusting the title alone.
The extras are the Hailong standard set. The key lock holds the pack to its base and doubles as theft deterrence.
The LED indicator gives a rough charge level, and the power switch cuts standby drain. The USB port charges a phone from the pack, which the bullet spells USD in a typo but delivers either way. None of these are exclusive to this shell, and none of them are missing.
The waterproof claim deserves one caution. The bullet calls the case waterproof, and the same bullet hedges with the usual advice about seals. No IP rating is printed anywhere.
Treat it as rain-resistant, not submersible, and keep the pack out of pressure washers regardless of what the case says.
Common questions the thin record leaves
Is the LOCKBUS 36V 10Ah good value?
Not on arithmetic alone. At about 36 cents per watt-hour it sits among the most expensive packs we track, and the same factory sells bigger shells at 21 to 27 cents. It only makes sense when the short Hailong footprint is exactly what your frame accepts.
Can it run a 1000W motor?
The math allows it. The 30A BMS gives a 1080W ceiling and the claim is 1000W, so a 1000W motor at full draw sits just inside. No owner has tested it, because there is no owner record to speak of.
How long does the charger take?
At least five hours from empty at the included 2A. The parameters card allows up to 5A of charge current, so a third-party 5A charger would cut that to about two hours if you ever need it.
Should I trust the 5.0 rating?
Treat it as presentation, not a verdict. One rating and one fifteen-word text cannot confirm capacity, range, or durability. The honest signal on this listing is the arithmetic, and the pack itself has to be tested on arrival.
