Re: Charger like LiPro 6S

Guys, read the OP again.... I am looking for a device like this to put in a maker space attached to a school to use for eBikes and scooters and DIY projects. To allow for all kinds of visitors to charge, to support DIY, to troubleshoot, to teach. The charger system needs to be foolproof and safe.......

Re: Can EVs survive without subsidies ?

. After range the primary concern is costs of battery replacement. Much like concern for the life expectancy of the engine when buying an IC car. Having a long lasting motor is a primary concern. Purchase price and major running costs are much higher up the list. Battery life or motor life are sour...

Re: Wind and Solar vs Coal, Gasoline, Nuclear

What exactly are you whineing on about now jimmy ?
Trends are “shyte” ? Are they.
Or the time lag between temp and CO2 in the historical data ?
At least try to explain your point in adult terms rather than spoilt brat , non specific, insults .

Re: Wind and Solar vs Coal, Gasoline, Nuclear

So, are you saying there have been , and are, NO trends ? At various periods there have have been cooling trends, ( 1940 - 1975) and other periods warming trends (1980-2000), ?

Re: Wind and Solar vs Coal, Gasoline, Nuclear

Thats a pretty sweeping statement .
Is it all “rubbish” ?
..you dont beliee the climate is changing ?
You dont agree with the lag of CO2 behind Temp in all the historic data ?
Be specific.
Which points are rubbish, and why ?

Re: Lithium variable voltage charger needed to 62v

That is a very useful looking unit, if it does what is claimed. The issues reported in online reviews seem to be related to the MPPT input from solar, so using it as a charger from a DCpower source input, should avoid those problems. Whilst i have an adjustable charger for 20-90 volts, it is a MM jo...
