I need to replace the battery on my Swytch front wheel conversion kit. I don't need or want a huge battery. Any thoughts on this battery as a replacement?

On the surface, it's fake. Hailong make battery cases, not batteries. If they're going to cheat by putting that name on it to give you confidence, they've probably cheated somewhere else. Apart from that, everything else seems to add up, so might be worth a punt.

The BMS limits look optimistic for unbranded cells so there's not much protection there. Does it fit the Swytch case and would it survive a corner impact if not?

afaik yose-power have a good rep for supplying batteries, the one i bought with the conversion kit i fitted over 2 years ago holds a good charge and is used regularly.

Greenlance.co.uk are another source members in here have used and recommended and have frequent discount codes.

chances of buying a pack built with quality cells, bms, and components are low if your not prepared to pay a reasonable price.

Any manufacturer who feels the need to say 8000mAh instead of 8Ah has already lost my trust.

In an accident or even a drop, that style of uncased cell pack is weak and prone to damage. No realistic ebike battery standard would permit them.

Buy a proper battery from a reputable supplier. They are not expensive.

Listing as 'mAh' is RC world battery talk associated with Lipo, for China sellers 8000mAh sounds more potent then 8ah.
However we aren't used to seeing Lion batteries listed in mAh, ah or kwh yes.
