Hi James

Can you give me a call I miss placed your number from when we talked in October. I would like to get a few of these batteries tested that we have. Just wondering if you know someone who could do a diagnostic test on a few. 4039885188 Charles
I know I'm annoying, but you still did not answer my question, Im looking at shematic of 2018 leaf ptc system, and I cannot see any wires that could tell ptc heater how much heat we need so the level of power must be controlled by a power transistor inside battery??
But that is strange?
Please help

Best regards

My question is , is the ptc output on the battery, connected to the same contactor as main power output?
Yes the wires are connected to the same contactor as the main battery. But the wires are extremely thin compared to the main battery wires. It is here on this picture on the bottom right. Small fuse and red wires.
thank you

who can help me , how I repair this situation ?

thank you 🙏

Obrigada pela ajuda, os cabos das baterias são de 10 mm , os terminais , são soldados .
Tudo muito estranho , as baterias são novas e as duas com a mesma voltagem 12,4 v …
10mm diameter cables should be OK.
10mm squared cables (cross section area) might be under sized.
The inverter may be faulty?
