I would be afraid of using too much voltage or not enough to charge my 12S.

So does that mean you will overcharge it if you don't disconnect it?
neptronix wrote: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.
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?

Ah I think for now the 20 amp I charger will more than meet my needs and It's tiny, and the power supply isn't any bigger than my 5 amp ping charger. So on the rare occasion I need to top up from home it will do!
BTW what's on my bike is torque plates not torque arms. sorry to correct you but they are two distinct things. Li-ghtcycle made those for me. Thank god for local ebikers with a garage PLUS a surplus of time on their hands cuz that took forever..[/quote]
Indeed you are correct, just a bad habit, like saying amps instead of ah for battery capacity!
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.http://beta.weather.com/weather/tenday/USOR0275
If your weather is worse than this, then yeah i feel bad for ya.
Well 30 mph gusts are not nice and 20 mph winds all the time the last few weeks, sometimes stronger sometimes less, but always windy!
So that's why I need an E-Bike lol
Look at the pic and I'm 5 miles north of the Carlow station!
London is a fair bit away and they usually get better weather than we do, though Wales and Scotland would get pretty much the same, though I think Ireland is far wetter especially the west and north, and windy as we get the full blast of the Atlantic!
I think the temps there and here are around the same and the weather, though the wind chill makes it a lot cooler here and it makes out door activities less appealing. It's funny when you look at satellite pics of the mainland mostly clear all the time apart from a few crazy thunderstorms now and then, but it can get very hot there and we don't get extremes like some places!
I love talking about weather!
Right I'm off to check my freewheel,
