42V 2A Battery Charger for 10 Series 36V Li-ion Battery Pack with DC 5.5x2.1mm Plug

It worked

Delivery was rapid, most important the product work straight out of the box no fuss first class service.

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.

Did the job it was bought for.

Our Gtech bike charger packed up when we were in France at the start of an 8 week trip….Amazon delivered to France and in three days…brilliant service from Amazon and the charger works well too. Saved our holiday.

Don’t buy this product is dangerous.

Bought as a replacement for the original supplied scooter charger. It works and in fact has a brighter charging light than the original. Much easier to see in bright daylight.

Good quality
