42V 2A Battery Charger for Electric Bike Bicycle DC 5.5mm*2.5mm connector for 10 Series 36V Li-ion Battery Pack

Delighted with this. Replaced lost charger for my kugoo s1 & it performed perfectly on first charge. Time will tell obviously but so far thumbs up. Very good at £10 cheaper than direct from main supplier.

Brilliant charger , Brilliant price 👏

In my use, it would charge to 4.05V/cell (pack voltage of 40.5V) and no more. This is around 90-95% of rated pack capacity and will somewhat extend the pack's cycle lifespan, but you don't get a choice in the matter. Whether it's a QC issue or whether this needs trimming, I can't tell you as it's a sealed unit and so I can't access its PCB to check. Like any other passive SMPS it runs warm, even hot, but this won't harm its longevity in any way.

As described

Much better than the one that came with my scooter, worth buying
