yep have cycle analyst.
I bet the sag won't be near as bad as on a ping!

It may be, if you have steel cover plates. I can't run disc brakes until i get new cover plates. :|o00scorpion00o said:My motor is better than yours!
o00scorpion00o said:Interesting stuff David,
So will you take that charger with you while out and about or use it as your main charger?
o00scorpion00o said:Does it cut off when the battery is chargerd? I'm sure it senses when the current drops? I think There was a vid posted here a while ago of someone using a meanwell but with much higher current and I think he used a battery medic to balance which I think would be rather slow? But you are lucky that you don't need to balance much!
I would be afraid of using too much voltage or not enough to charge my 12S.

neptronix said:Nope, it is not designed to cut off at a certain amperage, it should just float at a very low amp level until the battery is disconnected. As the battery nears the end of the charge though, current will slowly taper off until the battery holds it's voltage.
neptronix said:As for charging too high, see the wattmeter.. i can adjust the voltage via the potentiometer in the front.. not too hard, just multiply your target average cell voltage by the number of cells and set the meanwell to that voltage.
neptronix said:If you're nervous about it though, you can look into one of those bmsbattery shell chargers. They do make really high watt ones.
neptronix said:The weather here sucks too, i only get out maybe once a week. next week's forecast is more intermittent rain and constant cloud cover with the threat of a sudden vicious downpour.
New york is mid 70F and sunny 80% of the week right now.
London is getting 4 more sunny days over the next 10 days.
Almost halfway through the year and we haven't had more than 3 days of consecutive sun yet.

So does that mean you will overcharge it if you don't disconnect it?
o00scorpion00o said:Okay so 4.15 volts x 12 = 49.8. so setting it to 50 volts should do?
I'm assuming the charger will have to cc or cv or both?

neptronix said:yay, i have a DD kit coming my way and updated versions of both cover plates.
I will survive i suppose. Will go pedal off some of the winter layer in the next week.
+1What direct drive motor are you getting David? and what voltage are you going to use?
