Hi,
Not an expert at any of this, but I found a lot of great information in the resources section about BMS and batteries. One that may apply to your questions is https://diysolarforum.com/resources/lifepo4-voltage-settings-guide-for-bms-chargers-and-loads.121/
There may be more :). I've just...
Could one just tin them yourself using some flux, a torch and the pewter from a recycled beer mug? Pewter is 90 mumble % tin and a bit of a few other mostly conductive metals, including copper. I reload and cast (edited) and use a bit of pewter to get a little better fill out as needed...
Nice link Zil. I read the whole thing and I think the last sentence answers Russell's question doesn't it?
"The chargers should always be connected to the same points as the loads."
Hey Russell, hope that wind we had didn't cause you too much trouble. Here at 7000 ft., it was no issue at all in Bijou Basin (Elbert County. CO). Other folks that don't live in giant hole like we do had some damage. Hope all is well with you folks.
