hey... thats great! yes please do let me know thanks :D I also have a friend with an ev who has the same proble...charging 72 volts whereas mine is 60volts. so Im trying to get the answers for us both. but that would be great if you do have one. we are taking our little EV to the Big green gathering...

Hi Paul, well... I've been doing electronics for 25 years... and stuff like that is.... simply...... confusing! no component values etc. SCR.... WHAT SCR? resistor WAHAT RESISTOR. too much theory and no enough hands on circuit building. :roll: It is supprising though that a SIMPLE battery charging s...

actually.... I was going to say... yes of course ...I'll ned regulation for the solar panels, Ive already got a regulator..... BUT THEN ...I REALISE.... its a 12volt regulator! :shock: I'll need 5 of em! mmmmm.... I can make a circuit (comparator using 741 or similar) to determine when the battery i...

Hi yes they would be at the 20 amp rate. I guess I would only half discharge them also.... so really Im only looking to charge at 6amps for 10 hours or so. ------------------ (I am going to eventually Solar charge them using 5 Solar Panels the panels are 55 watts each. out of interest do you know if...

Unfortunately no data on the batteries. they are flooded and have a plastic screw on top to refill them. they also have a viewing hole for top up level(well I guess that is what its for anyway) very similar to these http://www.tayna.co.uk/getimage.php?image=2235numax-l110.jpg http://www.tayna.co.uk/...

Hi Thanks for the replies, lots of info to munch my way through... cool! 8) the batteries are simply...110 amp leasure/Marine batteries... don't laugh! its all I can afford right now for my first battery set. :D I guess from the sound of it I could use my variac which is rated at 8 amps... (not sure...

Hi! :D Ive just made myself a controller for a charger that auto detects when the battery is at a preset voltage and switches off a charging circuit... this all works fine with on board micro controller LCD screen...nice HOWEVER... it basically opperates a relay that will turn the charging circuit o...
