"But with these 4 cells, they pull 0.3 amps"

Rooted. Massively high internal resistance. Not surprising they got hot.

Hot cells is a very good indicator of high internal resistance - they basically boil off the electrolyte and get worse and worse.

High IR cells are only good for stationary applications and low current draw.

I've been collecting bits and pieces for years now, just been fleeced through a divorce and need to have a cleanup and get some funds back again. All of this is in good working order. I'm located in Newcastle, N.S.W but happy to ship via pack-n-send etc to get this to you at your expense. I've got a...

NOW sold - Mods feel free to remove.

CellLog 8M - no longer made unfortunately.

Inspired by the concept of the stealth bomber, I set out to make a batshit crazy, no holds barred downhill rig, but without the weight of a rear hub motor (which kills the balance of the bike). Its based on a Craftworks DHR frame, and uses a GNG 1Kw setup which drives through the gears - Pushed hard...

Old iron core halogen transformers work well for this.

You set them up as an autotransformer. A 50W unit will give you ~4.5A, as you are only using the secondary to do the heavy lifting. Add more in parallel to up your requirements.

This MPPT charger will supply 82V at least, I've got it charging a 72V nominal battery bank, from a 50V 250W panel.

Its a boost converter MPPT - if input > output, then this will happen normally.

There has been quite a bit of testing with these, and people are reporting decent power, 4-500W.

Chevy / Holden Volt modules are the cheapest. Not the nicest form factor, but easy to split into 48V modules.

He had a brilliant mind, will miss his posts immensely. He was an asset to the EV community.

RIP.

Yeah I found a few of the exploding knockoffs too - wasn't real impressed...

You will probably find that they only adjust the threshold of the LED for 'charger' systems (to indicate when the battery is 'full' - the current falls below a certain level). That's what the CH led is for.

Looks like the same motor as used in the Zero.

Bugger-all information on the page.

What is the frame you are using? How did your 0-60 times improve?

Looks good, and your batteries are aircooled as well

And ECE papers also opens the possibility of sale to Australia / New Zealand as well, two markets with very little in the way of electric motorcycles, apart from the (uber expensive) Zero.

That TORK one looks very interesting. http://torkmotorcycles.com/ and http://torkmotorcycles.com/specification.html Pricing - $125000 INR = $2500 AUD (??!!) Although the asterix indicates 'government subsidies' 48V 72AH - 3.4Kwh - 100Kph takes roughly 7-8Kw to maintain on a flat road, so you would g...

You should be able to parallel the booster by putting between the shunt negative and the positive-most battery terminal. You can disconnect the main anderson and anderson splitter (mounted on the top battery) while you connect the booster. There is a small pair of molex connectors that have an LED o...

Good encoders incorporate all of these features - A/B, Halls and Index Zero.
Price is another question though...

Interesting. I'd like to know how you can get a 150Kg bike to 128Kph with a 3Kw motor... The 10Kw version looks interesting, something like a large RC motor into a motorcycle gearbox? Could show some promise. THIS - https://endless-sphere.com/forums/viewtopic.php?f=12&t=65731 - was what I think it m...

Current flow and potential difference are two different things. A current only exists when there is something bridging the potential difference (ie. your meter). You are seeing a weak current leakage current setting the case at the potential of the cathode, which you are measuring against the anode....

Get normal bolts and find someone with a lathe to centre-drill them for you and tap perhaps?

Whats the maximum the 96V can take? 120V?

I think that was 150A battery and 250A Phase correct?

Red LED is one I installed above the cycle analyst. It usually lights on acceleration (due to battery sag).

The battery gauge is only a voltmeter, ignore it. Use the cycle analyst.

The 600A rated one might though - biggest problem is getting rid of 600A X 2V of heat!

I just clicked on your high power controller link - the topology was exactly what I had in mind last night (reconsidering the IPM modules due to cost) including the 'power ring' capacitor! Damn... That's crazy.
