H HAILONG 36V 48V 52V EBike Battery Lithium ion Battery with Waterproof Case for 250W-1500W Motor E-Bike Bicycles for Mountain Bike Motor Bike/Trike/Scooter Conversion Kit

Works great on my wife's KBO Hurricane. I rewired the bike to allow this battery to replace the original battery that died. Looks like a normal carry pack on the bike and provides about 50 miles of range on flat rides.

I bought two of these batteries and am happy to now have a total of 34 watt hours of power. It has greatly increased my range! I have ridden 52 very hilly miles on my heavy ebike, carrying my heavy body and the additional battery weight, with power to spare. The batteries have been reliable, charging in a reasonable time. Good value, great performance.

The 10AH battery is cool, but I wish there were more mounting options than hanging under your top tube, or saddle. Some bikes won’t accommodate those due to frame design (thick frame folding bikes) or rider position (seat too low to fit under). I had to brainstorm creative ways to mount mine, and it’s cool. Also, I wish it had a power switch. That loud spark when plugging in doesn’t sit well with me.

The small 48v 10Ah battery is performing about what was expected.I have now used the battery for 2,000 miles with a Bafang BBS02B 750wAfter a 25+ mile ride in through hilly terrain, averaging about 15mph (used for pedal assist), the battery indicator shows 53% is left. When the battery indicator gets to 20% or lower, if the power demand of the motor get above about 250w, the battery will struggle to provide the needed power, so it’s best to dial down the assist control when the battery level down.The small charger works well and is easy to pack to take with you to use to “top off” the battery.The only thing I wish it had was a shut off. There is a very small 'spark' when plugging the battery into the motor and or charger.However, if you plug the charger into the AC outlet before plugging the charger into the battery, there is no ‘spark’.I now have 3 of these batteries that I use in rotation. For most rides and errands, one battery is ample. The small size great. No need to ride around with a big heavy battery on the bicycle if it is not needed. When more distance is needed, I just put another battery (or two) in my panniers. I use all 3 batteries, when bicycle touring and that gets me 75 miles… enough for me in a day.

I was skeptical of it fitting right but I have ancheer folding bike and the battery works great with it and it’s way better than the one that came with my bike this battery last away and does great in the heat. I gets me to work and I’m able to do all my errands without it even getting to two bars and it only happened once because I didn’t charge it . It was also packaged well. And on a single charge I do more than 9 miles and it’s not dying while I’m riding in the heat also really is water proof sprayed it with a hose then rode around it’s also secured with for straps I thought it would fall especially with the way I ride my bike but it stays on just fine i also bought the cheapest one so if you buy the bigger ones it’s a great investment wish I knew the battery was this good before I got it definitely will buy again when needed.

It works fine for my purpose (ebike) only complaint i have is that charger wasn't correctly calibrated shows green light even when the battery's dead and itdidn't have the mx60 connector on it which is fine since i was going to change it out anyways overall worked for me and voltage/amp hour seems within marginUPDATE3rd time i charged it and it wouldn't charge thought the charger was bad so i got a new one still wouldn't work decided to open it up to wire it directly and found the charge controller was dead

My original battery went bad after 1.5 years, after trying to get reply, regarding warranty validity , from the company via phone call and email w/o any response. I decided to search for an alternative battery. So I found this with good enough rating. With no experience playing with this type of battery, I concluded the following tips, for anyone trying to save $$ with alternative battery,Find related XP dual battery setup on YouTube, watch these video to get idea on how to open the wire compartment and disconnect the charging wire connection (mine XP 2.0 is a T-dean type, unlike some videos showing XT60 type)After the replacement battery arrived, it is a XT60 cord, so I bought a XT60 male to T-dean female connector.I connected the conversion connector head to its original wiring head inside the lower compartment.I need to buy a 30cm XT60 extension cord, 12AWG rating, next to connect the gap between this external replacement battery and bike wiring inside the compartment.A few notes to keep in mind while performing this setup,§ the final battery to bike extension cord connection is on live wire so "do the compartment side first, lead the extra wire through the hole at bottom, then plug in the XT60 connector to battery last.§ the original charger from Lectric is the same rating as the replacement battery charger, so you can just buy the battery without charger to save even more. That is if you can find such seller.§ see the zoom in photo to reveal how I placed packaging materials as cushion for this external battery, I did use sticky Velcro between bag and white foam cushion.Hope this helps.

If you need a new battery for your Ebike, look no further. I bought one a little back, and sadly to no fault of the seller, one or more of the cells went dead and would only charge to 50.6v. after a short discussion and a pic of proof of voltage test, the seller sent a new one and a day later (today) I received it. I absolutely love the case, love the battery and love the seller. Fantastic, buy one!
