My charger is set to be the right voltage but the old cells being 22 in
series string they need to equalized out at the top/end of the charge.
this requires some battery baby sitting,

if your cells are staying very well balanced then your voltage cut off
method/gadjet  may  be good .

your ebay gadget coud also be be good for those wanting to do a lower
state of  charge, like turn the voltage down   5 volts for a 10% lower top
charge.

I have 2 ev scooters with  22 and 24 lfp cells.

wheres the voltage cut off gagaet on ebay??

[EVDL] NMC cells ran below 2.5 vots n left

[ken via EV]

 I bought a pack or lihium ion of cells and they arived pretty much dead. 
like 0 or .25 each cell.

I used 306b nicad setting to bring them up to  3.00,  then swtiched to
lipo to charge to 3.70 .

someone told me that charging theses cells could be dangerous, because the
dendrits could lead dangerous overheating. theses battery i think where
used for like a bus or something. theses are from

https://www.techdirectclub.com/johnson-controls-24-cells-solar-battery-90-vdc-total-2-5-kwh/

theses cells can do 10c so i'm rather concrned.  I wish I knew that
manufacuter or specs or more about the cells property.

there must be some kind of modaul that you'd input  on seconds / off seconds,
 then it would run a relay to controll charger on/off  or program an

both packs I have have shunts on each cell, but the bms is not sensing

shunts. it would be slow but non damaging.

lituium and do the right combination for voltage etc to power theses  or
get some kind of voltage controller to adjust. then just hang the bulb on

[ken via EV]

France’s Minister of Environment Ségolène Royal has officially opened the
world’s first solar road this week with one kilometer and 2,880 solar
panels in Tourouvre-au-Perche. Now the country is waiting to see if the
road, built with construction company Colas‘ Wattway technology, will live
up to the hype surrounding the clean energy experiment. The road is
designed to produce sufficient power to electrify street lighting in the
3,400-person village.

[EVDL] Ev scooter / bike sound generator

[ken via EV]

 Being an EV scooter rider, I'm very silent around gas cars. I take back
streets just to be SAFE. My town has some 2 n 3 lanes in town streets.
I'm thinking of getting a head light modualator. but that will not help
being seen by those on the sides of me .

My idea is an electric engine sound. Basicly put a magnet on the spoke,
and a pickup, the pluse would go into an amplifer and into a bass tube
speaker that would make a thumping sound like an engine and faster you go
the faster the thumping would go. of coarse you'd have a switch and volume
control.

or maybe the circut could be used modify other sounds for those of use how
choose to Quiet and not polute our failing earth.

To here the sounds of wind, birds, water while I ride is so nice.

about using a part of the pack cable to make a temp Shunt  or using the

some ev scooter manufactores are selling  72V33AH  SAMSUNG 22P SDI lithium

The capacity of lead-acid batteries is about 50% of the initial capacity
after 1.5 years of use (about 400 cycles), but that of Li-ion batteries is
about 75% of the initial capacity after 3 years of use (about 800 cycles).
As the minimum required life for an E-scooter is three years,..


Whats so important about this??.. when LFP gos for  2000 cycles aat 80%.

is it cost? 800 cycles would be about 2-3 years driving and LFP much more...

 When my SCOOTER not motorcycle fell over while parked on the side of the

to my SCHOCK American Family Ins. considers the Plastics as being  FARING
and is not covered under the standard policy.!! I said I don't have an
added handle bar Farings, crash bars, etc..  the little trunk on the back
got somewhat cracked, but I guess thats an "add-on".  I said the plastics
are where you put your Feet, and where you Sit and the Scooter come from
the  Factory that way as a whole stock bike!!  Again American Family Ins.
said "Its FARING its not covered" !!  you'll have to get extra coverage
for that ...   Check with your insuance company to make sure Standards
Plastics are covered!! This could apply to fiber glass bodies on 2 and 3
wheeled Evs . Or maybe even Kit Cars where the Non stardard passenger
sitting or covers are involved .

[EVDL] leaf 60ah vs calb 60ah cells

[ken via EV]

 For the case of like a 60 volts to 125 volts for a traction pack for like a
scooter.. why do some choose leaf cells ? seems like you have to get a
more specialised/ costly BMS like orion. I've seen youtube about Vectrix
conversions using both. leaf cells are american  made ? do they have more
cycles or power density ?

[EVDL] 5 k pot wiring? controller wiring? mis match

[ken via EV]

 I have a very simple controller i'm using on my scooter.

 throttle cable it shows
Blue, green, black
_

Controller manaual says

Red   WhiteBlack
5V   1-4.5V0V

SO WHICH GOES TO WHICH?

Is the white the wiper?


I thinks its 5 k pot? does the a hall affect show resitance across its leads.


I'll have  the back wheel off the ground for testing.

[EVDL] Battery Types

[ken via EV]

 Is there a chart that shows all batteries types and the number of cycles,
enegery density, heat runaway,etc.

I guess theres something called MCM lin min ???

they seem to be a lttle cheaper than lifeo4 but the voltage far off a
lttle faster ..

Re: [EVDL] AC motors for mowers

[ken via EV]

Thanks for the possible explation.

I gues for know I'll use the bike controller.
I found out 1 thing that this one has a low freg some thing in it and
it makes my motors BUZ hard at low speeds.

 Hi Ken,
 I am not sure how a hall-effect throttle works other than that it uses
 magnetism instead of a resistance trace. I believe that the throttle
 itself uses an AC voltage in a coil that is affected by a metal plunger
 attached to the throttle pedal, but I am not sure and it does not matter
 if the output from the hall effect throttle gets converted to a standard
 0-5V throttle control voltage somewhere, then it is easy
 to take the pulses from the hall sensor on the mower axle and turn those
 into a control voltage also to automatically maintain RPM (rev up the
 motor if the hall pulses indicate that it is slowing down) this may need a
 simple inverting opamp to get the correct feedback, once you have the
 correct control signals.

 Hope this helps,

 If you are interested in the 36V DC motor, it even has a Hall effect
 sensor on the axle that sits on top of the motor, to maintain RPM under
 varying load, in case you'd like to add this to your controller (I
 think that simply integrating the pulse output over time to get a DC
 voltage representative of the speed and combining that with any throttle
 input to the motor controller will do the trick. I believe Worx calls
 this intellicut


 I am working on using a controller to slow down the motor for power
 savings and noise for lighter grass.

 how complicated is to ad this to my existing controller that has a hall
 effect throlte?

 I would be nice to have it maintian constate speed .


 I the a cheap way to do this with out using a Bike controller and an add
 on.

 could I by the board from them or ???

 I built a box to put my headway cells in with bms, but the speed control
 would be nice also.

I converted gas edger an DC electric powered one. but I want to do with

[EVDL] AC motors for mowers

[ken via EV]

Where do I find the AC motors that are used to run the mower blades that
are on the decks of the riding mowers like Recharge n Zeon hustler etc.

I looking for myabe 750, 1000 watt motors.


Also whats the differance between Dc brushless and Ac motor?

AC is 3 phase and Dc brushless has electronics on the motor that changes
it to AC ?
