Bring it too NM and cut my lawn...lol the grass is high, because we just got 3 inches of rain!

Here's a couple of pics of the Battery Box with the Batteries all hooked up.
Technically 16s16p. Made up from 16 packs of 4s4p 12.8v nominal 9ah linked as 4s4p.
Each battery pack is 4s4p A123 LiFePO4, then 4 pack in series and 4 in parallel

It's a spaghetti mess of wires, but easy to change out a pack or re-purpose the packs for use with ebikes :wink:

Nice job on the build there Tommy L. You should put a safety switch on the seat just in case you fall off and the mower keeps going and chops up your children or pets.

But I would have smoked the motor in about 5 minutes in my yard. It rains a bit each day and it is still growing like crazy. Usually I get a break in July and August. But just last Saturday I had to creep along to keep my 17hp Kawasaki from stalling.

Thank you Major!
Not overlooked! I wanted to keep all the safety features, but they all seem to go to ground to kill the ICE.
I will put in my own momentary switch under the seat, very ease to put another switch in-line with the main toggle :wink:

UPDATE!!!!


This is working extremely well. I'm using Delta Qui Q 1kw charger. If I'm out for 20 minutes, the charger charges the pack back up in approx. 40min
I love electric!

Do you think there are any problems with using this motor in particular my question is/does the sprocket damage the shaft in anyway?

 

[Tommy L]

I see this motor on ebay for $325 .[/http://www.ebay.com/itm/Motenergy...he original Dual pulley from the gas engine.

 

[Tommy L]

Also, watch the Video a at the 10:00 mark.
It shows the pulley.

 

[wineboyrider]

The ebay link shows the same motonergy motor with a sprocket, but I imagine it is keyed to the shaft. I just wanted to know if the sprocket was removable without damaging the shaft? The price is right though.

 

[Tommy L]

Mine was a keyed shaft with no sprocket.
