YOSE POWER Hailong Ebike battery 36V 15.6Ah for 36V 350W / 500W / 750W motor fits on Down Tube for MiFa Prophete Pedelec

I have been buying from this seller on eBay but get faster delivery from AmazonI have been buying since 2019 and each battery still going as good as when I purchasedAWESOME COMES WITH FIRE PROTECTION BMS INSIDE EACH BATTERY

I first purchased a 36v 13ah Yose powerpack aprox £180 which developed a minor fault within few weeks but Yose organised return which dhl collected and Yose immediately refunded. I then purchase an alternative Yose 36v 17.6ah ‘ish’ which I’m still using at the moment it doesn’t get as many miles as I expected but it’s still working (2months use). Does aprox 22 miles on throttle & does take a while to charge (8-10hours is normal). But Yose customer care is great they have a very knowledgeable, helpful guy at littlebikerboyz (barking) who is their uk tech support guy. He’s really helpful on any issues or even just guidance on using & charging these E bike batteries correctly. Overall 5 star customer support and technical support. That’s both to yose & littlebikerboyz London UK.

Bought this to power my ebike conversion with a bafang mid mount motor, and I must say I'm impressed. Yes, it's not cheap but nothing is these days!On my first ride I did 17 miles along a canal towpath... mostly level ground and mixed between peddaling and using the throttle but didn't need to use full power at all.Battery is still at 69%This should get me back and fore to work with a few hills for a few days at least.Well happy with it!

Although this battery seems to have a little longer battery life than my previous one, this does seem to have an issue with charging speeds. I’m going to get a quick charger at some point in the future and hopefully that fixes this issue.A second problem I’ve found with this battery as well as my last one is the mounting plate. The frame holes haven’t lined up on my current frame or my previous two so I had to use zip ties ruining the overall looks of the bike. This battery isn’t the only one I’ve had that had this same problem. My 36v Yose Power also had this issue too.The USB port is relatively slow, 1A is probably being a little optimistic as it doesn’t even provide enough power to keep a bike light charging while in use. It’s still useful though, it’s not uncommon to find yourself running out of battery on your bike lights.Battery sag does seem to be a small issue with this pack, at full throttle under high load conditions, it drops 4-6V. Not sure why this is but it does cause the BMS to cut power at full throttle when you have around 25% remaining.The pack itself can handle around 25 miles on throttle when used at 1,000w. Dropping to 250w limited mode gives you around 30 miles range throttle only. Pedalling can significantly improve the range.
