good product very reasonable price
Bought to charge 52v 17.5 Ah Lithium ebike batteries. Used twice last weekend and they worked well, not overheating batteries as they charged quickly. Mains leads not such top quality, one having already failed with a dry joint inside connector body. Not a big issue though as better quality leads available cheaply and the chargers themselves are top quality. Charged batteries to about 60v BTW.
