Picture of 4p2s (20s) Edit: 3p2s connected with this harness to a single jk bms.

Yes, uses common plug. Comes with pigtails and acquisition pcb.

Should be a near direct swap to semi clone an 80v gen 4. You need the offroad polaris dld to start. Why would you consider this? A Ranger doesn't really need hotrodding. 35mph is easy enough at 48v, and oem controller can handle 60v.

$1200 for 4 delivered.

Usa stock ships for $50 conus Balance lead pigtail and acquisition board included molex mx-150L 360a cont 600a pulse Totally potted, rugged design https://altairnano.com/products/battery-module/ Random samples test over 60ah @100a rate Singles $350. 8 pcs in ss shell 750lb on your freight $2,000

Trade for new S4 80v Gen4

Think I got it now. These are cca buttons that I can solder to easily. Tig spot welded to cells. Testing on a beer can 60 amp 100ms pulse.

Solid nickel better, easier? Not sure I have nickel. Any other material, cu etc.? Also trying cca button. Weld al to al and solder to cu side. Some success but not ready to do batteries yet.

Practicing spot welding tig on a beer can. This 100ms and 60 amps. Nickel plated strip. Small 18awg aluminum wire is tough to do. Also able to weld copper plated aluminum for soldering.

Tnx, good info. Worth any amount of work for me. Saving a 12 brick battery by repairing one or two cells is a win. Is there anything to coat tops with to prevent oxidation before welding? I tried split plated strip at full power with Sunoco welder. Not enough power? It melts the strip. More...

I'm not building a pack. Just need to repair a few fused wires on the pack. The K-weld site says no, just as every other post I can find. I have not yet bought a new welder. Price is trivial if it works. Do you have cells to try? Glad to send some out for test welds. (usa)

Can't find a place to order k weld in USA. Anyone have one for sale? Although, I haven't found an aluminum success story yet.

What makes this welder suitable for aluminum? Over, say this one.

Wire fusing amps is about 5. I often blow them when building reconfigured packs. If you can teach me how to spot weld anything to positive terminal, it will save me a lot of time and money. I need a way to repair my mistakes. I've tried aluminum, copper, and nickel ribbon. Enough power to...

I too am looking for answers. I have been splitting tesla3 modules into useable lengths. So far I have not been able to repair fused links. Today I tried various methods and materials using an 800w 40khz welder. Zero success so far. Ordered a smaller horn/tip today, but I have little confidence...
