I will upload some pics
Done around 7 local batteries now
Will find some nice pics and upload
Builders discretion⌠I have some Iâm not proud ofâŚ
Just a few things. Use fishpaper every time a balance cable crosses another one. You did this a few times, but itâs missing on some. Same with charge cable, of course. Also, some balance leads are directly on top of the nickel or even solder joint of another cell. Thatâs not good. I canât see any tape that holds the p-groups together? Are you just going to heat shrink it all at the end? There should be some sort of tape, that holds the groups together, so that the stress isnât on the wires. I canât tell, if the solder joints are flown on the nickel nicely or just sit on top. Iâd probably add some solder and reflow some of them. Other than that, I can just recommend fixing the cables and tidying everything up a bit more. Then Itâll be a good pack (:
Itâs not unsuitable, itâs just amateurish. I wouldnât feel comfortable taking money for it unless itâs closer in polish to Sky, Duck, and the other pros.
Well but polish is just that, polish. Still looks like a rock solid pack. If Iâd to pay extra for polish, I wouldnât.
This is the stuff that I shouldâve prevented originally, and I can go back and add small pieces of fishpaper before I heatshrink it.
the underside is covered with 3 layers of FG tape. I can hold it from the middle and it stays together and flexes a little.
The solder joints are sticking to the nickel nicely, theyâre just ugly. I tried reflowing some of them but something with my technique is off and it doesnât come out too great.
why did it take so long to ask this question, who tf used a blowtorch to strip wire
WTF how is this a failure mode?? When my probes stick, nothing happens until I take them off and weld again.
Or maybe something else
Youâre misunderstanding. The welder stuck, the probes were stuck to the nickel dumping current as a result. Not the normal sticky probes you wiggle free after a weld.
oh, the welder failed completely. I thought this was normal behavior for your welder whenever it sticks. Scary as fuckâŚ
sounds like it would be a control glitch he said he was using it wrong whatever that means. Do not use it wrong I suppose.
Anyone have links for good quality in-line mini blade fuse holders? Iâm looking for something thatâs at least 15A rated (16AWG wires) and preferably with silicone wires.
Iâm pretty sure I have seen links like this on here in the past, but I cant find them now
Any help would be appreciated!
I have never seen those things with silicon wire. But there are dozens of the cheaper kind on ebay, although thats probably not the kind youâre looking for.
Second one looks identical to what I use which is not silicone wire. (First link appears to be broken)
To be honest I think they were both plastic insulated after reading some reviews. Grrrr.
I havenât been able to find anything silicone insulated. Most of those are being used in cars and such where they donât care
For my custom batteries, I use a 15A axial fuse soldered in line with the charge port, which is extremely low profile (see the fused charge ports on my site if you want pics of this method).
I need these fuse holders for production batteries where user serviceability is a must.
Sounds like Iâm going to have to go with a PVC coated cable fuse holder oh well! Thanks for helping out yâall
slide silicone tubing over the PVC wires. I was thinking you could 3d print a fuse holder because they are just blade connectors in plastic.
