    Adding more solar to my existing off grid setup

    I'm considering my options for adding an additional ground based array to my current off grid solar setup. This extra power would be to help run AC side loads in the summer time (EV charging, domestic appliances etc) that have a higher demand than our current 2.4kW array can produce. I...

I'm thinking of going for Samsung 21700s from nkon.nl Is the INR21700-50E really OK for 10a discharge? I think a 13s2p pack would fit in the space i have. I could limit the tsdz2 to...

    E-rickshaw / utility cart axles from China

    Does anyone have any experience with the e-rickshaw axles that come from Aliexpress? I have a small petrol powered utility cart that has a very unreliable briggs & Stratton petrol on it, 5hp (which is overkill really) that would be much safer and easier to use if it was electric. I think one of...
