Delivery was spot on. I had not used the light unit until this las week. Its bright! So bright, that a rider in front of me thought it was a car light. The front unit is quite heavy and could interfere with other necessary items on the handle bar, like your mounted Garmin. It could do with something to say it has recharged fully instead of waiting 5 hours, which is quite a lot of time. If there is this function to say how much it has been charged, I could not see it.
I would recommend this bit of kit despite the downside of weight and time it takes to charge.
Easy to order and delivery quick and efficient.
I’ve not taken apart to check the actual cells, but everything else about the battery and charger I’m very happy with.
