Sources for Electronics / BMSs in Germany


#1

Hey Guys,
I was planning a new Hub motor build with a selfmade 18650 battery (12s6p).
When i came to ordering, i saw that a 78$ BMS costs another 76 bucks shipping to Germany (batterysupports.com)…

Does anyone know a good source for this kind of stuff around Germany / other EU countries?


Reputable BMS vendor (aprox. 12s 80A) in Europe

I only paid 10,80€ for shipping to France, just bought the BMS for 10S @ www.batterysupports.com. The only alternative I found for europe is http://shop.lipopower.de/ but they are not cheap either which is the reason why I went with batterysupports.


#3

We could share the shipping cost by organizing a group order for EU people.
I bet that several people from the french forum of OKP would happily join !!

Was denkst du, Flatsp0t ?


#4

Yes, we could do that


#5

Well that sounds reasonable
i also thought it should be around 10-20 bucks but:



#6

Sounds way to high for such a small part. Have you tried contacting them via email?


#7

Yes, i mailed them yesterday, but i got no response until now.
But it is never bad to check for alternatives :slight_smile:


#8

I’d probably be in for a group buy, too.
Recently I’ve also found this side:
http://www.groetech.de/index.php?main_page=index&cPath=26&sort=20a&page=2
Doesn’t say if it’s Li-Ion, Li-Po, LiFePo… but it seems like they are mostly sellin Li-Ion batteries.


#9

actually this could be a option as well, got my li-ion cells from there: http://www.b-volt.com/accessoires-electriques/21-bms-pour-batterie-li-ion.html

Thank you both for the nice links.
my problem is, i need 100 A cont.


#11

Sounds great with a group buy! I’m in!

Some show-off for the german audience:
Ich wohne in Dänemark aber ich verstehe and spräche ein buchen deutsch.

@flatsp0t 100A continuous, this is loads! whats your ESC, you planning on a VESC? The wiring has to be crazy too, 100A really? I’m thinking the 60A I’ve been planning with are already over the top.

@OskarCastrone, not bad man, ich spreche leider kein Dänisch, try to lean french at the moment but struggle a lot.


#13

well, 4 vescs in an awd hub motor setup, ready to climb 28% hills with ease


#14

plus, i want a bit of headroom on all components, so 120A max of the cells, 100 at the BMS and maybe limiting the VESC´s on 80.


#15

Great I’m in as well! Have you bought Jacobs motors as well?
I’ve orderd two of them and I maybe upgrade to four when you get your hands on some decent BMS’s.
Grüße


#16

ok now I understand, sounds wicked :slight_smile:


#17

If there is a good deal on a BMS count me in.


#18

Yes, ive bought jacomotors, but i have no idea how the 4wd will perform.
So i recommend not spending so much money on an unproven concept.
But yes, if it works as expected, it is a monster.


#19

Yes same with me!
If it works it’s a monster or you struggle with an unfinished product.
