Hello to all !

This year i had the option to buy a cheap but rosty E-Gator for a few bugs .

Hello again some new Photos

here is a lost picture ...work on the axel





now its getting interesting ...............

the controller -gasket was broken i made a new seal (luck there was only a little oxidized inside )

inside the controller



so next work clean the DC- motor and repair the dead TachoPOL-Wheel



much dirt inside



the old TachoPOL was broken so every broken Magnet build two new poles (North andSouth)
Thats the reasen why the motor turn to slow !

i build a new tachoPOl with little neodymmagnet N-S-N-S-N-S

after clean the motor i chek the Brushes they look really good so i dont change them !

[E-Chopper]

So next step was build a new Battery i am not really a fan of acid Battery so i build a new liion Battery .
Old Battery more then 200KG the new one under 30kg

I buy cells and solder it !

close to fin


so i want that the Battery look like a original battery from a shop .i think it will look like a profesional Battery

i also mount a 200AMP fuse and a main switch !

Looking sweeeeeet!

Whats the Ah and voltage of your new battery?
New cells or used?
Brand name of cells?
Whats your range calculations?

I dig the build!

[E-Chopper]

Oh yes sorry i forget the data :

the cells are old 2014-2015 but not used = (0.0 Cycle )
i buy it for around 2,50 euro- pice (260 pices)

Cell data =Panasonic NCR18650PF 3.6 V 2900 mAh (10Amp max )

i solder 13s *20 Cells so i got 46,8 Volt nominal and 58 Ah

i know that 58ah is not much but i calculate this Vehicle for a max range that i need is 10-12 km so it is fine .

the Controller does made 400A max for short time but continous it is between 100-130 Ampere .
First test drive i controll the heat of cell´s but the never get real hot ..so this DIY accu is fit perfectly .
And the fuse is a 200amp fuse so there is no Danger to the Cells .


So i made some calculatoins and the range with this accu should be around 15km .
The maximum range i drive is now is 12 kilometer and the Accudisplay is not in the red range. I can not really tell you the real range its difficult to tell .

Maybe next time i made a video> offroad it is a really pure fun you can even drift the turn of the road .

I had never see one of these before and then yesterday my wife dragged me out to greenacres petting zoo in Wales for my 1 year olds amusement. Was a horrid day for weather. Animals were good but it was a bit run down as a place (its unfortunately a little oversold on their website). Anyway I saw an e-gator in the flesh and ironically a real gator/croc in the reptile house. Thanks for sharing I enjoyed the pictures.

Great job. How many Ahr were the original lead-acid batteries? Lithium batteries don't suffer so much from Peukert effect, so even if the lithium pack is less Ahr, it might perform better.

[E-Chopper]

first ! Hello again thanks for your post´s and interest in my Project.


Originally there was 8 pice acid Battery inside one had...... 6Volt -225 Ah (Trojan T-105 ) a cell had 28 Kilo so 224 Kilo .
But this Battery was all dead ! i took them to Recycling !

I know that 225 Ah acid Battery would perform longer ...but on other side they much heavier and the point of matter> the price of 8 new T-105 Battery was 1496 euro (one 187euro) the Liion Battery coast was around 700 Bugs .

Liquid Acid Battery you always must watch them fill Water in it .....

Liion you only have to watch to stay over 2,8 volt per cell

Nice project! I wish I had one golf cart like this to modify.
