Cheapest and quickest way to build a more mainstream size trike and better suited to the power, can be registered in America and almost every country except Australia
Price seems $2,000 to $4,500
If I could get it registered I would buy in a heart beat. $4,900 aud or nearest offer here.

I need smaller KW packs.
I think I might get by with two 4kw packs.
They would weigh around 200lbs.
This would be better for overall weight of the EV.

My thinking for a light, strong, very good life time, with save 18650 Quality cells 100V pack is:

24S 20P 2,1Ah cells (15c)

Voltage: rated: 24 x 3,70V: 88,80V

Voltage max: 24 x 4,20V: 100,80V

Kapa: 20 x 2,10Ah: 40,20Ah

Wh: 88,80V x 40,20Ah: 3569.76wh

weight: 480 x 50gr.: 24kg

max current: 603A

costs: 24 x 20 x 4,60: 2208 Euro


charger:

-2 x Hyperion 1420net with sync mode, 1100W charger power and balancer set-up for home and balancer charging from time to time

-charging time: 40,20Ah : approx. 10A charging current: 4h


-for superfast charging and as travelling charger

- 2x Siemens 50,40V PS with 2 x 2000W

-charging time: 40,20Ah : approx. 40A charging current: 1h

-or 2x 2xSiemens 50,40V PS for approx. 30min


For the last 6 month I test (+100cycles!) the new Sony cells with great results, my standard size is 12S8P, I have 4 sets for my Race-Trike and all is great!

Thank you very much for the battery pack configuration numbers!
I am planning to use individual battery packs for each of the two 4535 Astroflight motors. I will need two 24kg battery packs? 52kg is very lightweight. I have a 90kg to 100kg option of battery weight total.

I forgot to ask to see photos of your BMS wiring.
I am buying this resistance soldering iron for assembling the battery pack.

Hi,

please have a look to my thread:

http://endless-sphere.com/forums/viewtopic.php?f=14&t=54877#p817891

This batterys are good for high current discharge! A inexpensiv resistance soldering is only for medium or low current discharge.

How much is your estimate dischage current?

Ah, but this must be seen here, given some of the illustrations you've had so far.

What is that?
