@3DDave: "A/C impedence is an indicator of the battery overall health regardless of charge state."
Would the tested impedance be different at different SOC?
Thx
I'm trying to understand the load-resistance of an A123 Nanophosphate High Power Lithium Ion cell.

My understanding is that resistance increases as the cell charges.
The datasheet says "Internal Impedance...
Hello
I want to cast a polymer, epoxy, or resin. It must be crack-resistant when compressed. Prefer a clay or putty.
I tried JB SteelStik, and it cracked under compression.
Don't need bonding.
Fancy expensive products are not an option.
Fyi, this is related to a youth engineering...
I need a low-toxicity, low-melting point metal (before casting), to cast hardware parts.
After casting, the parts must not crack under torque or impact, and should remain hard up to at least 100 deg C.
My plan is to make a Tin/Bismuth alloy, since low-toxicity, low-melting point.
I've heard...
