Re: New Chargery 1500 24s charger

I'm thinking of buying this charger.

Does it work simply that I connect positive and negative wire and whatever setting I have inputed it will start charging?

thanks

Re: sabvoton SVMC72200 blew on 1st run

What is your voltage from your battery?
What is your battery power level and setup? Are all its connection good and have you tried your battery so that it is OK?

If you can; how does your controller look inside and do you know if a part is broken if you se it?

Re: concerns about lipos

6s lipo Check total voltage = V X voltage i.e the one cell you wonder about is y5+x = V Known voltage is for example 24,5 and cells 1-5 is 4,2 volt each then 4,2*5 + x = 24,5 ( -21 x = 3,5 voltage of cell in this example is 3,5 If voltage total reads about 25,2 volt as it should then your last cell ...

Do you have a CA connector on your Greentime controller? (that is like a display connector) displays does have buttons and on/off switches. If you don't know which wires need to be used to turn the controller on/off or if you don't have a display or CA then it can be hacked. First open the controlle...

Re: Searching low € / kWh battery chemistry

I second that. Samsung 29e cells or (Panasonic) with good cycle life and performance.(10a or 2-3c continuous) For a big pack I like it to keep its kwh and not lose capacity after 100-200 cycles.

Re: First battery build

Nice try.. Quite similar as my newly develop 416 Open Frame Power Pack kit. http://bit.ly/416OFPPK Soldering is fine if is for small area. When you have large area, the consistency will be affected. Another disadvantage of soldering is it fixed. Cannot change. Of course, the benefit is you have a l...

Re: Random battery combination idea.

I don't get it. Will you charge one battery with another when you ride? How long would it take to fuel if you do a long range race? I mean 20 minutes, can you stay and charge that amount of time when petrolheads fuel theirs? A fast charger are more costly so why not even get a larger battery. say 50...

How much to buy all?

In summary I ask What is the output signal from a hall wire? What numbers of wires do I need as a minimum and how do I connect this/these wires to only get that signal? You may have figured this out, but here's my two cents. On my Sabvoton, for any connector that has a black wire (throttle, halls, ...
