Re: Hire E-Bike build thread

The other thing to be careful with on your pack design is to made sure that your two halves that are connected together in the pelicase don't have terminals which can accidentally touch again shorting out the pack. Either use something to space them that is an isolator or have your terminals facing ...

Re: Hire E-Bike build thread

Yep the last image is right. The bus bar is unnecessary and dangerous if it is essentially shorting out the very high amp capable cells.

if you want 14s you go 1 2 3 4 5 6 7 8 9 10 11 12 13 14 "-+" "-+" "-+" "-+" "-+" "-+" "-+" "-+" "-+" "-+" "-+" "-+" "-+" "-+" i.e. the pos of cell one connects to neg of cell two, the bms wires tap off neg of 1, pos of 14 and every connection in between. with that bus bar (or rather 3 of them) "-" "...

Re: Hire E-Bike build thread

It still doesn't make sense to me. if you use a bus bar, this is to parallel cells, you have 14 cells packs and if you use a bus bar like the one in the photo you will be making 2s7p which is a 7.4v battery with a load of ah. It may just be me but I think that bus bar you are showing isn't what you ...

Re: Hire E-Bike build thread

I'm not sure I understand the bus bar you drew. I thought you are running 14s and if so that pic with seven holes in doesn't make sense to me. Are you cutting that bar into cell connectors (and if so didn't agnuism provide those, cause he did for my mate who did a similar 10s8p battery)

Re: Hire E-Bike build thread

well the negative obviously needs to be on the most negative and the positive goes on the most positive terminal but all of the ones in between it doesn't matter whether they are on the positive of the lower cell or the negative of the higher cell as that wire is at the same potential difference (ne...

if it is a scam then some companies listed in the autoblog article are going to be sorry as they are already partnering with linear to use their HET systems in cars and scooters. 2-3 years till we see the real thing allegedly.

Re: Hunstable HET Electric turbine

Thanks stans. I am already familiar with nearly all lebowski developments, see my sig.
Posted this to see how many other people had been prototyping 3d printed motors and throw this idea toward them.
Hoping in time that these leaps forward in larger ev's trickle down to the smaller ones.

Hunstable HET Electric turbine

https://www.linearlabsinc.com/why-our-motor/ from what I gather its 2 types of motor packed together like a sandwich. but actually 4 motors in total. The two main electric motor designs are called radial flux and axial flux, which employ a fixed stator and one or two spinning rotors. Linear Labs cla...

Re: Lebowski controller IC 2.A1 source code and (short) explanation

Thank you Bas, I realise how frustrating it is to not get exactly what you initially envision from a project. I think this step along with putting that source onto github is a huge step forward and will help so so many more people use your work for the greater good, both from a learning perspective ...

That does help abit, it didn't have the exact matching one but now I know how fast/slow the fuse should blow. the rest of the info was on the lid engraved anyway. but I learnt a little bit there. Thanks AW :thumb:

A colleague came to me with a request to find out where he could buy replacement fuses like these fuse2.png around the top they says 250v and T3.15a when searching for replacements its easy to find 20mmx5mm fuses but I cant find these 14mm long ones anywhere. They may be 20 or so years old but our w...

Using complete toolpacks to build a powerwall

So I have had this idea that I would like a powerwall which serves many purposes. I bought into quite heavily one type of 40v toolpack battery, which I also can power a mower, strimmer and mine and my wife's ebikes. Kind of irrelevant which battery it is but it comes in 2.6ah and 4ah at 40v nominal ...
