I am embarking on building my first battery. It will be used as a replacement for the battery in an ICE motorcycle. I am fairly comfortable with basic battery setup - a123s in a 4s1p configuration - it's a dirtbike so has very little electrical accessories - headlight, rear / brake light, electronic speedo / odometer (even the headlight is only 35w). The OEM LA battery is rated to 130 cca, so the 120 amps 10 second burst rating of the a123 26650s should be fine.
3 questions;
1) I have 0.15 nickel strips for battery connections. I have read around and noted that these are rated to around 5 amps each. This I assume is continuous - how should I scale for burst applications? Should I scale for 120 amps (i.e. 24 strips / 8 per connection) or something else?
2) For the main battery connections I will be using 6awg extra flexible welding cable - would I be better to use this as connectors between cells also?
3) I will be soldering all together (have a 100w iron) - the soldering of a single tab to the cell terminals I am fine with. However are there any good resources showing how to solder stacks of nickel strips - do I solder just the ends? The whole length of each tab? What's best practice for soldering stacks of nickel tabs?
