I thikn I will be fine with the watt meter.. but maybe i should consider a buzzering meter. But with the bm6, you are only monitoring 1 pack (severals cells) ? or does it monitor the complete battery in series/parallel ? edit: Btw, the Bm6 get extremely lousy reviews on hobbyking...

I've been trying to contact bmsbattery.com about the faulty battery. They dont answer me on mail. I have 2 of them on skype aswell and even though they are online they dont answer any calls/chats. Its a warning to others who intend to order from them. I bought a HobbyKing hk-010 watt...

It could be that its not been fully charged. I honestly dont understand that chinese charger i received with the kit. The charger has 2 LEDs on it. when i plug it in the wall the left LED is green and the right one is red (this right LED is constantly red, never changes color or go off while...

Its about 10 seconds under power

Hmm ok.. What could i do with the battery to fix it?

I have a weird problem with the bike. I charged the battery like a week a ago. And yesterday I took the bike for a trip, After about 2km of full power the green light on my 3-led thumb throttle turned off. and after about 1 km more, the bike completely lost power. None of the leds on the...

You should be really careful with lipos. If you poke a hole in the foil, the battery will burn/explode. Search for "Lipo fire" on youtube and you'll see what i'm talking about. I cant even imagine what would happen to that big pack of lipos you got, if you would to damage it. Also, never ever...

Update: rode with the same uncharged battery for 35min at mostly full speed, mostly uphill. So I guess it was the extreme cold affecting the battery. But I feel that I have to invest in a watt meter.

This is probably the reason. I assumed that the battery was charged when i recieved it (measuring 39.9v) but i guess it wasnt charged. Sunday evening i charged the battery full, and i measured the voltage right after the charge, it was at 42.0v. Yesterday, before i went for another test trip i...

No but my test ride was without pedal sensor. Only a thumb throttle, controller, motor, battery. And i'm certain i didnt open the throttle due to pedaling. It was like a "skipping" feeling. Maybe i'm just getting it wrong, bear with me. :) I just get the impression from what you write...

Great pointer! Thanks. I took the bike for my first test ride today. quite a heavy wind and -18 celsius. Pff. I was just out for 10 minutes or so, couldnt stand more. I tried quite a steep hill and experienced some weird behavior. Or maybe its not weird..? It was like pulses. Like 2-3...

That cycle analyst is really ridicoulsly expensive. I do some RC as well. those watt meters by turnigy or hobbyking cost like $20. I agree that cycle analyst have some functions that the other ones dont have. but hey, its the same hardware. I guess i did set it up correctly. it just looked...

Haha ok! Actually it doesn't even surprise me.

Thanks for all the answers guys! The circuit i've made is as if it was to "switched on". That was what i was wondering. because i see that the battery has a "charge setting" in the "key ignition". Thanks Its the bms controller "KU63 - 6Mosfet". I guess its 36v/250w Didnt know about...

First of all, Hi everybody, this is my first post. I've been lurking around this forum for quite a while and reading other threads. There is alot of helpful information posted by people here. I decided to go for a Bafang (8fun) qswxh motor and an aluminium alloy 12aH, 36v battery. And i...
