90AHr LiFePo cells plus charger and more for sale

When I dismantled my EcoRolla and sold the motor and controller, I kept the 45 x 90AHr cells (thundersky and winston) plus all the extra stuff listed below, because I was going to add EV grunt to a toyota prius C. But now Im not, so I want to sell the lot to someone who needs to save some money on t...

Re: Renault EVs

Im excited about the Zoe finally being available too. So many cars are going to come, going to come, and then dont. We drive an Outlander PHEV every day. Its perfect for our longer camping trips and shorter local stuff but I drive about 100km round trip to work and the PHEV battery just wont and I c...

ADC 8" motor. Zeva Controller

So there is no interest in this at $1500.
I will drop the price to $1200.
I would rather it all went into a project vehicle than sit in my garage!

TC Charger or What?

Interesting questions. You are exactly right about how much capacity the cells have after shunting starts. When the pack was a bit more out of balance a cell might start shunting while the charger was still on 15 amps. I think that was the problem with the design, the pack voltage needed to get quit...

TC Charger or What?

The TC charger has been in now for a few months and is working wonderfully well in fact, **** The new charger has solved an ongoing, mysterious, battery balancing issue. ***** Basically two cells out of the 45 never charged up to the same extent as the others and therefore would discharge to danger ...

TC Charger or What?

Hi Eric
I bought from EVPower. All TC chargers are $595 plus GST plus Postage. Works out a little more than from China which is probably the GST.
But it was in stock and supposedly is in the mail now.

Well, I have ordered one and the auspostie says its on the way. I do hope it lasts longer than the other one.
The good thing is that the EV could be back on the road in a few days.
Thanks

TC Charger or What?

Hi Jones?? No it just stopped kicking in. Usually when charging happens a yellow LED starts flashing slowly. Now, the yellow LED begins to flash and I can hear a zzzzzing sound from inside the charger. Not like a spark discharge more like an electrostatic discharge. Something is wrong. I have asked ...

Hi all, My EV is becoming like the lifelong hammer. "Lasted for ever. Only replaced the handle twice and the head three times" The charger stopped working. (I have already replaced the motor. The controller needs work, possibly replacing, now the charger has stopped) TC brand chargers are mentioned ...

Help with drop in Torque

Thanks Peter, I slowly become more aware of what is going on electrically. From Ian's earlier posts about his Curtis experience too, it seems to be much older design technology. And their reputation for reliability must be questioned. I don't think its only Australia too, the USAians seem to be unha...

Help with drop in Torque

I think you all maybe right. The car is still driving. I can still go up our hill in 2nd at 60-70kph but its harder to get there and I have to start anywhere in first. The syncromesh is getting more of a workout and complaining a bit. Our other car just blew a headgasket / cracked head and needs abo...

Thanks again Ian for that very informative reply. I read your article on the 1231. I think Im lucky to have mine last so long! I read the earlier stuff again and will firstly look more closely downstream of the controller, at the connections, motor brushes, everything. Other electric car owners and ...

Help with drop in Torque

Hi Ian again I went out in the car and tried some stuff. At standstill, if I floor the accelerator in 2nd, 3rd etc, the current doesn't get higher than 20 amps at first. If Im on the flat, the speed slowly builds and the current rises with the motor speed. There is no appreciable drop on the voltmet...

Help with drop in Torque

Hi Ian The controller is about 5 years old. What you say makes sense wrt the performance Im getting. The other possibility is something wrong with the sensing of the pot. I don't know anyone with a big clampometer but I don't think the controller will deliver the big amps as if I go flat to the boar...

Hi Mike, Ive run over the battery terminals with my inbuilt contact thermometer (my finger). Nothing seemed hot, mostly slightly warm. Ill check the voltage drops in various gears. I also have felt the various connectors to motor, controller etc. after a drive. Hoping to find a hot spot. No such luc...

Hi all, I have a 91 Corolla conversion. 144v LiFePo, 8" Advanced DC motor and Curtiss 1231C controller. Just recently I have lost the ability to accelerate from low speed in 2nd gear. I have to now start in 1st up to about 35kph then change. Once the car is up to maybe 50kph in 2nd, the acceleration...

Advanced DC 6.7" 144v motor DAMAGED

I finally replaced the X91 motor with the 8" model in my 91 Corolla conversion. It has had a few rebuilds in its two year history with me. It has had the commutator lathed and the ammature glue replaced and recooked twice. The brushes and bearings were also replaced once. The third time it failed, t...

Toyota Corolla Conversion

Whoops typos late at night. I meant 260 amp. The voltage is nominally 144. Thanks for the comments. I have been slowly recrimping ends as I notice they are getting loose. I thought that loose crimps might be causing the hiccups even though I would have expected arcs and burnt ends. Im sort of glad t...

Its a year since the last post. Time does indeed fly. We have been driving the car for that long with a few minor hiccups along the way. Ive rerouted some cables.
