Re: Battery Pack Wanted on West Coast

Is it that you have a bad pack or a bad cell? In July or so my warranty will be up and if Vectrix manages to delay and delay (at which they are expert) I will not be getting a battery fix via warranty and might be interested in popping replacement cells in my pack, but I don't think I need a whole new pack ('cause I am so expert and diagnosing these issues).

If you find some used or new cells and wanna split the cost and shipping I am near and we could try fixing the packs together...

Re: Battery Pack Wanted on West Coast

Sorry - I should have been more specific.

I have a VX-1 (NiMH) with some bad cells - I thought if I could find someone that had a VX-1 that they'd be willing to sell the battery pack from - I'd buy it to salvage some good cells to replace the bad ones in my pack.

Randy - I see you had the same thought - good idea to share the cost - and maybe we could both fix our bikes.

Anyone with a VX-1 NiMH pack for sale?

I've got a pack for sale...but it comes with the rest of the bike too :)

constant discharge 0,3 C... 40Ax0,3C= 12A. The vectrix in a hiway needs 70-100A of constant discharge. These cells are not suitable for a vectrix!

Not suitable means: It will work with the V, but instead of 2000 cycles these cells would only last 200 cycles. We need better cells.

Another problem: How to order? Direct via the manufactuer? Tricky and riscy if there is an waranty problem with the cells...

We are 60000 square meter size manufacturer instead of broker or trading company,we take 100% responsibility on warranty.

0.3C is constant charging current,not dicharge. 0.3C charging is good for battery life.

Discharge is 5C,pls read carefully !

How strange.
5C stands for maximum peak discharging current, but not for maximum constant discharging current.

The cells can only assume a constant charging current of 0,3C, but you declare that they can suffer a constant discharging current of 5C and last 2000 cycles? Are you really sure?

Re: Battery Pack Wanted on West Coast

There is no 5C constant discharging dymo machine in china,but we test all kinds of batteries TS,GBS,CLAP...on golf car,when full accelerating,their voltage drop very quick even lower to 2.7-2.8V,but our CHL keep 3.1-3.2V even at 5C discharge current !

What we mean 2000cycle is based on 1C charged and discharged,this is standard.

And 0.3C charging current is standard charging current good for battery life.\

I don't believe there is a 5C discharge battery could be 2000 cycles,even BYD or A123

And 5C constant discharged is needless on real world.

On practice,most of big discharged current only last 10-20 seconds when accelerating,because current will drop immediately as soon as vechile reach top speed.

But some bad quality lithium battery don't even bear such low period big curren,because of their bad impedance.

Sure, but it also depends on the speed.
At 110 km/h constant speed the vectrix may need 90-120A -> 3C. At 160 km/h constant speed it will need over 200A-> over 5C.
Maybe somebody with cycle analyst on a Vectrix can tell us the real values...

Re: Battery Pack Wanted on West Coast

120A with 3C constant discharged would be definitely not problem for CHL battery,but 40AH is still too small to be install on Vectrix or 160km/h maxi scooter,we have 50AH too,and 100AH will come out very soon !

Hi!

Hmmm.
What is the measurement of the 50 and 100Ah Cells??

110kmh requires between 80A and 105A @ 137v on my Vectrix.

max acceleration current draw is 230A.

40Ah cells can do that, with some loss of service life.
cells with lower internal resistance do better.
SE 70Ah cells are the best fit I have found so far, mainly because of their physical dimensions.

at that speed you don't have much range, I normally go for bigger batteries more for the range than the extra service life.

btw -> 160kmh needs 300A @ 140v, its a cubed relationship.
incidentally that was the top speed of my petrol bike, even though it could do 0-100 in 5.5 sec.

A Vectrix has to be heavily modified to get to that speed, both to avoid the motor rpm getting too high, and a more powerful controller.

Our 100AH battery will come out 2 months later.

Now 50AH is 184x47x115cm

Terrific,
That means the list of available compatible (with the kit I'm developing) LiFePO4 cells for a Vectrix is:
TS 40Ah
SE 40Ah
CHL 50Ah

and with panel modification:
TS 60Ah
SE 70Ah

CHL:
out of curiosity,
was the CHL 50Ah cell designed for a specific application?

Every manufacturer seems to have a cell that fits inside 190 x 47 x 116

I hope, 100ah have the same diameter ;) or only a little thicker...

Since TS is the poineer of square Lithium battery,so that most of battery boxes of EV are design accordingly,so that following lithium manufacturer have to choose similar size to get the testing opportunity !

I still have a bunch of loose cells. I can't vouch for their condition, but for the price of shipping you can see what you get.

I know I will go out of warranty this June/July so if I haven't heard from Vectrix on getting the bike fixed before, I will be looking to shunt or replace my problem, not that I have even opened it yet for fear of making things worse.

Re: Battery Pack Wanted on West Coast

Since I started this thread I've been watching antiscab's progress on the Li-ion conversion kit - it seems logical to invest a bit more into a bike that will be more practical and last longer. I've pretty much decided to go for it - I just have to order the kit and the batteries....
