The LGECOLFP 36V 15Ah is a Hailong style ebike battery. 540Wh for 36V systems. LGECOLFP is a brand from Guangdong TianChi New Energy Technology Co., Ltd., a Chinese manufacturer that sell multiple voltage and capacity options under the same listing. The specific variant we're looking at here is the 36V 15Ah, and the listing also includes 48V and 52V versions of 15Ah to 20Ah capacity. Uses a 5 pin mounting base, has an XT60 discharge connector, 3A fast charger included along with a pair of keys, and the pack manages the cells with a 30A BMS. 34 reviews and a 4.2 star average across all versions. Costs per watt-hour on our comparison table are therefore quite competitive.
For 36V systems the amount of stored energy at that voltage is fairly generous, meaning longer rides, and especially in a sensible product. 540Wh is well above the 10Ah packs you normally see at this voltage and gives you a decent measure of range before plugging back in. So the 3A charger also helps since so many in this price range are 2A, and therefore you're looking at a somewhat quicker charge time. There are some caveats of course, but the reviews make for mostly positive reading, with one or two blips of warning about customer support if things go bad.
Specs and Value
On this one it is a simple sum, 36V times 15Ah gives you a generous 540Wh. For a 36V battery this is towards the top end of what you'll find without stepping into a premium category. Price per watt-hour is at around 0.35 per Wh, so not the cheapest 36V out there, but you do get an entire kit in the box, and just the 3A charger would take a bite if you were to buy it separately.
Physical specs
Listing gives dimensions of roughly 14.47 x 3.7 x 4.17 inches (for the 48V variant, the 36V will be similar size or a little smaller, as it uses fewer cell groups). Weight is 8.95 pounds for the 48V, so the 36V will be a bit lighter, probably in the 7 to 8 pound range. It is a Hailong-style black housing that slides into a metal mounting plate bolted to your frame's downtube. LGECOLFP includes anti-vibration pads pre-glued to the battery base, a small touch that reduces rattling and helps protect cells from road shock.
Included 42V 3A fast charger is sized appropriately for the 36V 10S lithium ion pack. It will take roughly 5 hours to charge from empty to full (and saves 2 to 3 hours every charge cycle compared to the bundled 2A chargers that most competitors put in the box). Also in the box are two keys for the safety lock, a 5-pin battery holder mounting plate with female XT60 discharge cable, a male XT60 discharge connector, the anti-vibration pads, and a user manual.
BMS and motor range
The built-in 30A BMS covers all the standard protections you'd expect, so short circuit, overcharge, over-discharge, over-current, and over-temperature. At 36V and with a continuous 30A discharge, that's about 1080W of theoretical power output. LGECOLFP state motor compatibility of 0 to 1200W, though for a 36V system realistically you're going to be riding motors in the 250W to 750W range. Even a 1000W motor on 36V would be fine within the BMS limits, but you'd be approaching the maximum discharge rate which isn't great for long term battery use.
LGECOLFP state their cells are Grade A and that the battery carries UL and CE certification. They claim more than 1000 charge cycles before significant capacity loss, which sounds reasonable for decent lithium ion cells, though without knowing the cell brand and configuration it's hard to evaluate their claim. Even if you got 600 to 800 real world cycles out of it then, you would be years into regular riding before you'd see much degradation.
Form Factor and Compatibility
The Hailong form factor is one of the most popular battery shapes in the ebike world, and the LGECOLFP follows that standard design. The battery slides down into the housing on a metal mounting plate that bolts to the downtube of your bike frame. Installation is pretty straightforward, just bolt the plate down, slide the battery in from the top, and lock it in place with the included key. The mounting plate uses slotted holes so you get a bit of adjustability for positioning around water bottle bosses or frame hardware.
The battery uses a 5-pin discharge connector on the base, the connection point between the battery and the mounting plate. The actual output for your controller is an XT60 connector coming off the mounting plate's wiring harness. XT60 is a common connector in the ebike world and in RC hobby applications, so if your controller uses XT60 you're good to go. If not, XT60 adapters and pigtails are readily available and inexpensive. One reviewer mentioned using the included pigtail adapter to get it working with their Rad Power ebike, so there's some flexibility there.
The safety lock on top lets you lock the battery to the frame when you're leaving your bike somewhere, and also prevents the battery from accidentally sliding out while riding. The LED power indicator on top gives you a quick visual read on remaining charge level without having to turn on your display or check an app. LGECOLFP also states that this has a waterproof case (which should be good against rain and splashes), but like any Hailong battery you'll want to avoid submerging it or shooting a pressure washer near the seals.
Real-World Range
With 540Wh of capacity on a 36V system, you should look at getting reasonable range potential. On a 250W to 500W motor with moderate pedal assist on mostly flat ground, plan on somewhere around 25 to 40 miles per charge. If you are powering a 750W motor or riding hilly terrain and using a lot of throttle power, that drops to maybe 15 to 25 miles. These are rough estimates and you may get more or less, depending on rider weight, tire pressure, wind conditions, how much assist you're using, and how much throttle you use vs pedaling.
For day to day commuting purposes, 540Wh is comfortable for round trips of maybe up to 15 to 20 miles each way on moderate assist. And with the 3A fast charger you can top off during the work day if you need to, returning a depleted battery back to full in approximately 5 hours. And if you are just running around town for short trips, you may go two or three days between charges. The LGECOLFP 36V 15Ah stacks up against the other 36V packs on a capacity basis, and you can see where it falls on our comparison table sorted by price per watt-hour.
What Amazon Reviewers Are Saying
The LGECOLFP 36V 15Ah has an overall score of 4.2 out of 5 stars based on 34 reviews on Amazon, just keep in mind that the reviews are an aggregate for all voltage and capacity configurations on the listing. Overall its a net positive.
A few reviewers mentioned this as a good replacement option. One buyer picked the battery for their Rad Step Thru ebike after learning their original replacement battery was cost prohibitive, and getting the pigtail for the plug worked, along with tweaking their holding bracket, and after several charge cycles the battery is working great. Another reviewer uses their battery in conjunction with a second battery, and found that it charged up to the correct voltage and feels quality built. And another shopper has purchased five of these, and plans to buy more, which is about as strong an endorsement as you can get.
One interesting review is from a dirt bike rider who mounted it to their dirt bike with a hub motor. They ride hard on trails that are steep, and even after a crash where the bike flipped and landed on its side, the battery remained intact and powered right back up. The reviewers also appreciated that the battery comes packaged with foam protection and an easy to install mounting plate, and that it holds the charge well, even after 6 months.
On the downside, there is a negative review warning of bad customer service. The reviewer ran into a battery issue beyond warranty and found the company not particularly responsive or helpful. With a 30-day return window and 12-month warranty, you do have some protection, but post-warranty support may not be reliable based on that experience. Test the battery thoroughly when it arrives and make sure everything works within your return window.
Who Should Buy This
The LGECOLFP 36V 15Ah makes sense if you need a 36V battery with generous capacity and want affordable power without paying too much. Getting 540Wh at this price point is competitive, and the extra practical benefit of a 3A fast charger in lieu of a 2A is nice to see. The 5-pin Hailong mount with XT60 output is compatible with most of the wide range of 36V systems available, and the included pigtail adapter gives you some latitude if the connector doesn't match perfectly.
On a 36V system, the 30A BMS is good for motors of up to about 1000W, though most riders will be running 250W to 750W and won't be close to stressing it. Safety lock, LED indicator and waterproof housing are welcome, too. Reviews indicate that this is a well-built battery that can handle real-world use, including rough riding conditions. The main concern here is customer support if something goes wrong after the warranty period, so keep that in mind and test your battery early.

Frequently Asked Questions
What charger comes with the LGECOLFP 36V 15Ah? A 42V 3A fast charger is included. That's the standard voltage for a 36V lithium ion 10S pack, and the 3A output means it charges faster than the 2A chargers most of its competitors include. Full charge from empty takes about 5 hours.
Does the LGECOLFP 36V 15Ah have a USB port? The variant tracked here does not have a USB port. LGECOLFP does offer a USB version under the same listing, so check the variant options if you want that feature.
What connector does the LGECOLFP 36V 15Ah use? It uses a 5-pin base connector that electrically attaches the battery to the mounting plate, and the output from the mounting plate is an XT60 connector. The box includes a male XT60 adapter. If your controller uses a different connector, XT60 pigtails and adapters are inexpensive and available.
Will the LGECOLFP 36V 15Ah fit my ebike? It uses the standard Hailong form factor that mounts to downtube frame tubes. Confirm that you have enough clearance on your frame for the dimensions (roughly 14.5 x 3.7 x 4.2 inches) and that your bike runs a 36V controller. The 5-pin base is the standard Hailong mount, but you may want to check that it matches your existing mount if you're doing a direct replacement.
How many charge cycles will it last? LGECOLFP claims over 1000 charge cycles. That's within the realistic range for lithium ion cells, though actual longevity of the pack varies widely with charging habits, conditions, and how deeply the pack is discharged. Conservative estimates of 600 to 800 cycles before the pack noticeably loses capacity still translate to several years of daily riding.
What warranty does the LGECOLFP 36V 15Ah come with? 30 days to return and replace if necessary, plus 12 months of warranty coverage. Based on review feedback, test the battery promptly when it arrives to make sure everything works within the return window.
