Batterybro.com good source?

Hello all. I found a post from a few years ago stating that https://batterybro.com was a good source for 18650 batteries. I just wondered if anyone has conducted business with them recently and if they’re willing to share their experience about how it went. Thanks. :?:

Re: Spot welding fuses to individual 18650 cells?

One other question regarding the type of individual fuse to use: Given the motor and charge controller specifications listed above, I thought the following fuse wire would work well: 36 SWG Tinned Copper Wire 500g FUSE WIRE 5 AMP 0.20MM Any thoughts or opinions? Thanks in advance for any ideas. Gary

Re: Spot welding fuses to individual 18650 cells?

Thanks for the response. I may use the method demonstrated here:

Do you foresee any problems regarding too much resistance within the circuit if I use individual fuses on the battery pack with the 72v motor/charge controller? Thanks again for all of the information.

Re: Bus Bar Question for Electric Go Kart Battery Pack

marks, Thanks for the response. I do have a spot welder so I appreciate your idea. One follow up question: Would the nickel strips increase the resistance since it is not as conducive as copper? Another idea I was considering was to spot weld small fuse wire onto a copper bus bar like this..... http...

How much did you pay for the racing go-kart frame? That looks great. I am searching for something similar myself. Any suggestions for a newbie?
