Re: E-Moto battery connectors melting....

Older vmoto had hardwired batteries, and vectrix did have a connector in the middle, but that was a 125A anderson, with a 125v system voltage. That connector is way undersized for 50A continuous, which at 48v is what is needed to hold 60kmh. To be honest, you would be better putting a second battery...

Re: Geerant's Magnatron

The cells in my Vectrix have 2010 manufacture dates (Thundersky) and have been in daily use since 2010 (at ~2000 cycles now) and have 2/3rd of original capacity
I agree, the shelf life is certainly longer than 10 years

Re: Outlander PHEV Chademo Slow Charging

The battery is too small to take more power. Or put another way, the chemistry doesn't support charging faster than 1C

fast chargers don't do much for small phev batteries

Hi Dave,

Re: Andrew Forrest and the 2021 Boyer Lecture

the amount of material for hydrogen storage tends to get overlooked. To store 5kg of hydrogen takes an 88kg carbon fibre tank (700Bar), or 500kg of metal hydride (think Lavo at relatively low pressure) or 300kg for a steel unit at 60 Bar. Add 60kg of fuel cell (for 110kw capacity or so, that can con...

The station itself would likely be converted to a synchronous condenser too, so the infrastructure would need to be maintained into the future anyway

Re: MPP HV2-5048 Earthing of output

When testing potentials, did you use the meter in LOZ mode?

Otherwise you will be measuring with 1MOhm of meter resistance. 48v measured at 1MOhm suggests 4MOhm of isolation between the two

Re: 3-Phase Adapter

We call those suicide leads, as it's easy to make the other male end live and exposed at the same time.

If on different rcbo it will also trip both rcbos

Note, you can usually get away with pulling 14A from a 10A point, as they're usually protected by a 16A rcbo.
