Available sizes are- 12mm, 16mm, 20mm, 25mm, 32mm, 40mm, 50mm and 63mm For our professional EV customers we mainly stock the 20mm, 25mm and 32mm sizes. Other sizes are less co...

We supply the high grade orange flexible conduits for professional EV conversions. Unlike the corrugated PVC conduit used by electricians the smooth bore conduit we supply our customers makes for a more professional looking EV conversion since it is very easy to wipe down to keep looking as good as ...

DC Circuit breaker 400 amps+

Thanks Guys, The idea is to use the circuit breaker as an emergency on/off located on the battery box (which can be reached from the drivers seat). The main reason is for that extra peace of mind just in case the contactor gets stuck in the ON position. I will still be able to shut down the high vo...

DC Circuit breaker 400 amps+

To answer both acmotor and 300zxev there are several reasons for my choice of the circuit breaker. I guess alot of it comes down to my years of experience in the electrical industry and particularly in the UPS industry working on huge UPS's and their asscoiated large battery banks and the protectio...

Yes exactly. I like this feature. It doesn't require an external power source to energize it and make it work.

DC Circuit breaker 400 amps+

I am actually in the process of ordering a 400amp circuit breaker for an EV project this week. However it is an industrial circuit breaker and wouldn't be suitable and would be too expensive for use in an electric car. I say it wouldn't be suitable for an electric car since this is for my big electr...

Over the years I have pretty much written off CRC and WD40 as requiring too many repetitions to be that useful. I'll look at a spray wax I think.

Hey Geoff, Last week I dropped off a dozen LiFePO4 battery packs to a customer in Lane Cove as part of his solar system for his house.

Kokam batteries

I agree with Zeva's comments entirely. Great energy density but at the expense of safety it is just not worth it. I will have a look at the catalog in more detail shortly but a quick look shows that the Kokam cells are definitely more hazardous than LiFePO4. There is certainly none of the shipping a...

Kokam batteries

I think you will find they are Lithium Polymer and a potential fire hazard. I saw one of the cells at a presentation night where Phil Coop from Energetique (evMe) brought one for display. I questioned him about the safety of the cell and he was clearly not willing to confirm they are as safe as LiFe...

What's really required?

If you want to build a high performance EV (plenty of power + long range) you certainly wouldn't choose a low performance lithium battery (less than 5C) eg, Thundersky, Sky Energy,etc. It just doesn't make sense! You would use a very high discharge rate cell so you really only have two choices if yo...

Ok, I knew Paul (cell_man) was not local but I see he is in China and not in the USA. He must be getting some cells from a source in China which were supposed to be used by a Chinese EV manufacturer (or some similar source)?
