You can buy tinned lugs from a good electrical factors supplying commercial kit to the electrical industry. Every power distribution...

They look like cheap, thin walled, non tin plated terminals. They will only accept small wire gauges despite the pictures. The low...

You need hydraulic crimping, especially with lithium. The high current potential of lithium will not tolerate high resistance...

I really don't know why @footsoldier made an issue out of this. I doubt any of us care how people refer to our country as long as...

Yes. They needed doing with a csrtain time frame but the trip by boat doesn't count so you do it before you leave. We had to have the...

I was surprised that the grade B Envision 280A cells balanced up so easily. I was expected to have to rig up my balance leads to put...

I swapped 700ah for over 900 ah and saved 50% space and 10 kg even though my previous batteries were lightweight anyway. I think they...

I assume that as the BMS asks for a reference voltage etc that should be set with the entire pack the same though as you say the JK BMS...

I just built a 280A at 24v battery (equivalent to a 560Ah at 12v) overall size is 400mmx 350mm x300mm high. Weight is 45kg. It's a big...

If you're going to install 'drop in' batteries, you'll need to upgrade to a class T fuse. And that means you'll need to make up suitable...

Yes time is an issue if you're doing a lot of packs. For someone building a single pack over winter whist the boat isn't in use, less of...

From a technical perspective, I wonder what that might be? The JK bms had the cells balanced to 2 mV deviation. The cells don't know...

I made my own busbars. You don't need class T fuses. Use NH series. Far more cost effective and probably better than class T. I bought a...

I haven't needed to balance the Grade B Envision cells, even though I have a bench top supply. I let the JK do the balancing and it...

The peelings out of the cured mixing pot are way more flexible than polyester. I work using both ( for different applications)...
