Sorry to hear about your BMS battery charger issue.
Its always the chance you take it buying from China at a hideously cheap price.

I personally have done the same from BMS but the 240w bulk charger. Which lets face it. Isn't that quick in the realm of bulk charging.
I hope mine works. But i've only paid £40 all in with the delivery. Which cost the same amount as the actual charger.

I hope you get yours sorted or fixed though. Nothing worse than having to slowly charge your packs...

Sorry to hear about your troubles you should get American made enginuity:D http://epbuddy.com/index.php?main_page= ... cts_id=170. I'm getting this setup and now all you have to do is get a charging harness from icecube and you are set! Btw I just got that list yesterday and they have some good reviews. I just ordered mine yestarday and in an hour or two they sent me a tracking number. Supposed to be hear today or tomorrow GOOD STUFF! Anybody have anything good to say about epbuddy?

[ohzee]

EPBuddy is pretty awesome. He's local to me so I have even picked up packages before.. I ordered some wire last week and had it to my door
the next day.. I do live withing 10miles though so I am sort of cheating . My 306b had a weird issue where the fan failed to turn on so I was concerned
how warm it was getting. I took it over to his house he pulled out a new 306b and a battery to verify the fan worked.

So yea EPBUDDY is good stuff.

[Trackman417]

And the best part, they are American! Are they based in Ohio? That's what it says on their website. So I'm guessing my package should be hear today or tomorrow:D

[rui_fujino]

Thanks guys for the alternatives but again, those chargers are slow balance chargers and k won't be able to bulk charge unlike mean well or bmsbattery...
I've talked to Judy Liu from bmsbattery and he said I'll need to take a picture of the inside and if its broken for non-visible reasons then he can send me a new one for free!
Mean while I might buy icharger so slowly charge...
Any suggestions of charger I can use that are cheap off eBay?

[Trackman417]

Ehhh slow? Lol 20 amps isn't fast enough? Haha geez you must be the fastest moving man in the world . Good luck with your charger:D

[Scottyf]

You can get lipo chargers from the UK.
A resonable priced 10amp (200w) charger from www.giantcod.com
will cost you about £40. But least that will charge your packs in a few hours. You will need a power supply though to run it.

Scottyf, thanks for the info but the web you tagged isn't working... also I am looking for plug and charge rather than those that requires power supply...

[rui_fujino]

well. while im waiting for the bulk charger to fix its self...I've decided to get slow balance charger.
does anyone familiar with Dynam Supermate DC6 Double Power?

I only got this cos it was cheap on ebay and i can charge 2x5s2p at the time!

[rui_fujino]

Hi, Here is update! Since I have uploaded few things on the other threads I'll put them here.
they are my current handlebar situation! I think they are pretty neat

FAS XC282 DH Handlebar:
CA-DP with Speedometer
Bicygnals Adaptor
3 way switch
Thumb throttle
Shimano EZ fire shifters
Custom LED lights
Cheap rear view mirror(to be upgraded)

Took a long time to figure out the perfect ways to put 3way switch, throttle and shifter/brake all together while keeping them look neat!

Here is my whole bike in snow!

Also update on the Charger.
I got the slow charger from ebay and It arrived today!

I have charged half of all the packs but its going to take more time to charge the other half...can not wait to get my bulk charger back!

[Trackman417]

Damn, I don't think I would ever be able to live with myself if I had that much stuff on my handlebars. How's the motor holding up? Is it getting warm on trips? Are you pushing the full 72V 40amps into the motor yet?

[rui_fujino]

YOU ARE THE 100th POST! lol
Yea its not too bad having that on my handlebar, but some of us in this forum do have insane amount of stuff on it
And yes I&ve run full 83v 50amps into the motor and since UK has been so cold my motor is doing perfect! Infact I can WOT for 5min and still dont get warm! but then the controller do get little warm

[Trackman417]

Haha well that's good! And yeah that's true about some people having so much more stuff on the bike than you do.
That's really awesome the motor doesn't get hot WOT riding at that power. I was hearing so many stories about the HX motors over heating that I was getting concerned and I'm going to run 40 amps do that should make a big difference in heating as well

[rui_fujino]

Well, recently (last week) I had a problem with connectors getting wet by the snow and my mud guard being useless...so I bought these from eBay and hoping to prevent my connectors getting wet.
Does anyone know better ways of waterproofing connectors while still being able to connect and disconnect the wires?

[rui_fujino]

My multi Switch arrived today! so this is my plan, I'm going to swap green horn push switch to normal switch so that push and it will stay on.
I didnt realise horn switch is smaller than red switch,,,but little sanding and all perfect! now my switch can turn on off my lights and controller!
(haven't thought about what R/L switch should do yet...)

also my BMS charger that are broken; Im trying to fix it so I'll upload few pictures when I know the problem...
but mean while here is what they look like inside:

[rui_fujino]

I've been away over the weekend and didn't get to ride it due to something went wrong with my motor and it started to make vibrating sound and no power...I suspected water got into halls connectors while its been snowing.
I've checked all and finally when I was about to give up I saw this...

IMG-20120220-00585.jpg

Rusting 5pin connector

(202.95 KiB) Downloaded 5 times

they are suppose to be waterproof as well as that, I put so many layers of heat shrink and all....I've cleaned them up and now its back and running

On other news, I couldn't figure out what went wrong with my BMS Charger 2 so I've decided to transplant broken parts from charger 2 to 1 and see if I can get one of them working...

[rui_fujino]

Its been quite a while since my last post but yet again, I made silly mistake...I accidentally shorted my battery for the second time. (Never charge when ur tired). I've checked the cells and they look fine (thank god!)
I haven't had time to make any upgrade or add switches but I'll do them soon.

Interesting news: my from speedometer has gone crazy when I hit 58mph going down the hill and it think it did 90mph!!

90mph?!?!

[rui_fujino]

Last night I took my shorted connectors and replaced with new sets and here is what I saw...

After KFF

I never thought those massive connectors could melt...

[BATFINK]

Nightmare Rio, electricity can melt a lot of things, I remember taking a factory apart and as I was disconnecting a wire from a live socket (some idiot was supposed to have shut it down) there was a big blue flash and the electricity melted the screwdriver, it actually cut the end clean off!!!

How did that happen to your connectors? Did positive touch negative?

[rui_fujino]

I was balance charging four sets of 5s2p and I've accidentally plunged battery and battery together instead of battery to the charger.

[rui_fujino]

Its been a LOOONG time since I updated! so here is whats going on!
My laptop died(7years old) so I decided to clean it up and upgrade to new HDD plus installed ubuntu(no virus) ...then I've got my self chain cleaning tool from ebay>>>
http://www.finishlineusa.com/products/chain-cleaner.htm
It is super effective! I really do recommend you guys to get this

Here is state on my ebike>

Clean bike!

Currently no change other than cleaner chain, disk brakes and a new side mirror
I do recommend using "white lightning Clean Streak" it removes all the dirt/oil/lube with strong degreaser spray and at the same time the liquid evapurates so no need to wipe them after! disk is now soo much stronger without squeaking! i've used it for chain cleaning as well!

Almost forgot, BMSBattery are doing sale at moment any all the charger has reduced price! since I am still struggling to fix mine I've got myself 400w charger for only $40!!

[Trackman417]

Looks good! However one thing that is concerning me ought now is where u placed ur lock. I mean sure it's a good place to put it, but if it some how gets caught in the spokes and you are at speed, you could get thrown off the handlebars.
I hope this helps!

Hahahaha funny how ur the first person to mention that , I've actually already had this problem but what happened was my lock just got ripped off the mount and nothing was seriously damaged but If you can think of better placement I would love to hear about it!
