Re: new eZip motor

Again, it's a bit of the "poor pay twice" truism. Having the right tyres and protective gear for winter riding would go a long way in mitigating the risk against just normal summer riding. As you might remember, I have been managing my cholestrol and blood pressure too, and it's finally in the norma...

Re: new eZip motor

LC has issues with patience and planning. He could save a lot of money if he planned better and was more patient. I've heard the saying "The poor pay twice", and I think that is true here in subtle different ways. You can buy a good quality, right sized battery pack, and it will last years. 7-8 if ...

Re: new eZip motor

How many of those batteries SUNDER posted would I need for the FX 75-5 motor ? Every one of those cells can put out 290w sustained, or 430W burst, but I'd leave some buffer as always. So to drive a 45kw motor, you'd need at least 105 of those cells in some kind of configuration - your choice of vol...

Re: new eZip motor

Not having money to not join packs is an excuse. You could probably just cruise around and look for an abandoned <anything electric> and cut the cabling off it and then make up a harness with 10cm of left over solder and half a meter of shrink wrap or electrical tape. Total cost if he didn't have to...

Re: new eZip motor

I was told earlier on that different capacity packs at different stages of life are not to be hooked together. Not to be hooked together in Series. You can even hook cells of different CHEMISTRIES together in Parallel, as long as you use the narrower of the two voltage ranges. Damn, you're making m...

Re: Sur ron advice AUSTRALIA

Not encouraging anything, but I wonder how they restricted the speed, and if it's reversible. Unless you were acting like a tool, there's no way police would know you had a 45km/h speed limit unless they had a reason to check your rego. That said, motorbikes are usually marked Mopeds because of unco...

I don't think any off the shelf bike rack would hold 120lbs. They're usually secured to the rear hanger, which isn't designed to hold that kind of weight. I could be wrong though, because bike pegs do exist, and they are designed for teens who could hit that weight, but not my area of expertise. You...

Re: Quality 60v inverter

Inverters designed yo take more than 48v nominal tend to be pretty expensive, because as someone else pointed out, they are usually for solar storage applications and need to meet certification, even if they don't have them. Easier answer for such small power is just to step down to 12v and use a co...

I saw that, but it said something like "Road legal under 45km/h", so is that like a special moped classification or something? Never seen a road legal bike with a speed limit condition before. Can't imagine taking a 45kmh bike on even a 50kmh road. Eventually you'd get an idiot running you off the r...

Re: 2.35v 11ah nos boxes of 12 cells

These are ideal for car audio. In fact, some people use them instead of lead + super capacitor for car audio - Better density than lead, and can deliver the very bursty power without actually needing the big AH (Unless the reason you need big AH, is not to deliver high power, but to deliver high pow...

Sunder, Only the liver can metabolise fructose. That's why it's so harmful. Every other tissue in the body can use glucose and indeed muscles run best on it (but not as much as you'd think). Consumption of fructose causes fat around the liver because of this, which is a large part of insulin insens...

Re: Optimal charging for batteries

Yes. You can feel that curve on the discharge side too. Go full throttle when the battery is full, and the voltage might only sag 2-4v (on a well designed 48v system). Try to do the same when the battery is less than 50% and it might drop 10v to trigger off LVC, even though you still have 50% capaci...
