Re: Need help balancing battery

How many hours will it take to balance? 45 mA difference with 40mA balance current. Info about this is confusing..

Re: Need help balancing battery

That's my question, best method to get all 13 series back to same voltage :D

Charge lowest to 4.1 and then charge the battery through the BMS?

A link to my BMS:

Need help balancing battery

Have a 48v 13s4p Sanyo GA battery and 12 of the series are 3.62v and the 13th is 3.58v, the 13th was much lower but used a tp4056 module to get it closer. Question is should I continue to use the module to get the voltages to match or use the new BMS I fitted to balance the battery? My bms has a bal...

Re: Bafang BBSxx - fault finding and fixes

The freewheel in the nylon gear seems to operate normally, only turns one direction.

Only option is to buy new one and see if that works with less resistance?

Re: Bafang BBSxx - fault finding and fixes

Can anyone tell me if the Nylon gear should spin when pedalling? Have quite a bit of resistance when pedalling and wonder if this is the problem? *edit* If i remove the nylon gear/pinion, there's no resistance when i turn cranks, resistance must be from either the bearing/freewheel inside the gear o...

Re: N.E.S.E. the no solder module

Can you tell me the distance between the left & right side of the inside? Printed a few and they're around 67mm. Which leaves only 2mm for the bars which seems far too tight.

Thanks.

7 days for delivery to UK, great service. Just to confirm, the 4p module download is the "v2"?

Re: N.E.S.E. the no solder module

Looking for help with some of the 3d printer settings as I'm a noobie. Using Cura with a CR-10.

Seems these settings are for a different slicer, and just named differently in Cura.

Perimeters - 4

Bottom solid layers - 5

Top solid layers - 6

Thanks for any help.

Re: DIY assembly kit for 18650 without spot welding/Solderin

I first contacted Vruzend on the 18th showing the damage around the bolt and was offered no refund or replacement. Told to build a pack to test and they'll be okay. On 19th I sent another message about being sceptical of building a pack as I was wary the cracks may get worse. "Make a pack. You would...

Re: DIY assembly kit for 18650 without spot welding/Solderin

The solution to the problems both of us experienced is simple - to slow down production. I would've happily waited an extra week if it meant all caps were assembled correctly. Also I'd not looked at the rest of the kit until now and I see that all bus bars are bent on one end :roll: :lol: I wonder i...

Re: DIY assembly kit for 18650 without spot welding/Solderin

Thanks for your reply but I really think I'll try open a case with paypal and see what they think, as they don't seem fit for purpose. The clear ones looked much better quality in your videos.. *edit* added another photo. I actually saw similar damage in one your videos. Just concerns me that it's g...

Re: DIY assembly kit for 18650 without spot welding/Solderin

Just checking the caps that arrived today and seems too much force has been used when inserting the bolts through the holes and the plastic has cracked. edit. Roughly 50% of red caps are damaged in the same way. If you look at the one on the right in the image you can see the bolt isn't central whic...

Anyone in UK have a spare vruzend 18650 kit for sale? Want to avoid the possibility of getting stung with extra fees when buying from India.

Re: DIY assembly kit for 18650 without spot welding/Solderin

Just wondering if someone can confirm if the kit comes with 100 or 104 caps? Conflicting info on the website. Need 104 to make 13s4p battery.

Thanks
