For any interested buyers: if the thumbnail is an accurate portrayal, it looks like the easily voltage adjustable charger. Take off one panel, and there are three pots. 1 controls current, 1 controls max voltage, 1 controls min current before shutoff. So consider the possibility of tweaking the voltage. Nicer than those fixed voltage chargers
My guy puts out 2A at 49.2v, and doesn't really get warm, so it's conceivable this guy puts out 4A. But we have also had another similar chasis charger claim 4A and not put out 4A.Mine was never advertised as 4A, and it was originally for 48V (this one might not get as high as 49.2v).
Edit: For future cross-reference, here's the thread about changing the voltages. viewtopic.php?f=14&t=35109
New to endless-sphere? Notice a lot of signatures recommending Ebike.ca? That's because it's the best place for a quality and manageable, (but still 'real'), first build. Justin is a solid supporter of electric bike development, and a good source of equipment.
My hat off a thousand times to the green people that effectively run this forum. The ES Mods are superb.
