I don't have a spot welder myself but a friend of mine has built his own so I plan to use that. I will also peddle all of the time. I live in a hilly area so it would be nice to have some electric help :) It will be a 17-22 Amp controller depending on the kit I buy and the motor will be a 350w...

Thanks :)

Self welding yes. You mean these https://eu.nkon.nl/accessories/welding-material/isolatie-papier-18650.html?

Thanks! Do you know where I can get them for 2.6Euro each? A lot of cheaper sources I checked didn't ship to Europe/Sweden.

Thanks for making this clearer for me Dan. Would it be prudent to always assume that the rated Amp capacity of the battery pack should be around twice the Amps of the controller (for builds in general)? Do you mean 'cheap build' for the battery pack I currently will have or the one I will have...

Thanks :)

Joakim do you have tips on how this build could be improved?

No doubt there is a lot of information and a lot I've learned already considering I knew pretty much nothing about batteries and such. Especially when it comes to avoid fake crap batteries, the right cells for my usage, etc. However it can get confusing and overwhelming for a newbie when...

I don't mean to 'cheap out', rather I'm looking for an optimal combination of controller, motor, BMS and battery. I had narrowed down the battery to the Panasonic NCR18650PF 2900mAh 10A but if the Controller/Motor won't be close to utilizing its potential then I didn't see a point in having an...

Hello, I'm still trying to understand battery packs and I was wondering what is the Amp for a 10S4P battery pack built with Panasonic NCR18650PF 2900mAh - 10A batteries? 40A since there are 4 in parallel? Thanks :)

Instead of a separate post I ended up posting this as a comment :D Please ignore this

Thanks for the reply, the controller will likely be a 36v 17A and the motor a 36V350W geared front hub motor. From what I understand from your post, the BMS I have should be ok since the controller will never attempt to draw more than 17A anyway? And am I putting too much money in the cells with...

Hi Salfter, Where are you planning to purchase your cells from?

Hello, I've purchased a BMS rated at 35A 10S from ebay but the pack I am building is with Panasonic NCR18650PF 2900mAh - 10A batteries, 10S and 4P. Since the discharge of each battery is rated at 10A, I'm assuming that it will total 40A since there will be 4 in parallel? Do I have the math...
