Joining two PIE power cables to one battery connector

Ohhh poor Monkey nobody reads his posts lol

60W is enough. I use a 'automotive' one that's 80W with a big splade tip. It was about $20AUD (so around £20 hehe)

If you already have a 60W use that, as if you ever have to solder onto a PCB (the BMS or controller for example) then you don't want something TOO hot.

Really you are just doing the wires, so even a blowtorch will suffice champ

Thanks for taking pictures, I need visuals

makes complete sense.  I will try soldering on a new connector first, as it is cheaper to buy one of these than to buy a pack of marrette connectors.   When/if it all goes wrong I will use the marrette as plan B 


I will get there, never mind how slowly!

The pictures are no problem. I just wanted to show you how simple the wiring can be and that you may be overthinking it.

Ive used a 48V before, just takes longer

Monkey, how far down the line did you go with the thicker wiring, all the way into the pie or just to the connector ?

i did read,,   I was just checking I had read it correctly!

Ginge,

got the Anderson,   I think that 'RS Components' is going to come in handy. just ten minutes from my work place.

do I need any special kind of solder or will any cheap solder do.  I've heard about rosin being used as an ingrediant in solder, do I really need this in the alloy mix?

[DirtyGinge]

To be honest I havent used it....not to any detrimental effect...have pulled 38 amps through these connections with both pies and no problems so far......im sure there is a reason, but don't know it yet 

RS components are pretty handy I must admit, just getting ready for my 5v relay install, to turn off one pie and enable disable the cycle analyst limiting.....might use another relay for throttle / PAS control on or off...........too much time, too many children, ....shed beer time

Andrew, I always use "flux-core" solder for electrical work and non fluxed solder for plumbing joints.

Flux-core solder already has the flux (which is needed to reduce oxidisation and help produce a much better joint) contained within the solder itself.
Most flux-core solders contain a rosin based flux, making them much more suitable for electrical work than the acid based fluxes which can cause big problems if the surplus flux is not removed thoroughly.

The alternative is to use a separate flux paste which is applied to the area to be joined prior to using non fluxed solder.

If you buy your solder from an electrical supplier, the chances are it will be flux core solder, but if you buy it from a plumbing supplier, it's more likely to be non fluxed solder.

Hope this helps.

thanks Alan, yep, makes sense
