Hello, my name Firmino, live in France, 62 years old and I am retired. Recently interested in 18650.
My apologies, i don't speak English and I use Google Translate. Well done for your site for finding 18650 specs and for the very useful "Pack Builder Tool". I will not be active on the forum due to having to dissect the posts, but I would benefit from your experience.
cordially

Be kind

Re: your Lev50Ns

You're too far away otherwise I'd be all over those like a badly fitting shirt (I'm in the UK with a battery pack in a very bad state)

However: can I be cheeky and ask you to snapshot a couple of cell barcodes?

I'm trying to work out what Yuasa blue/yellow/purple LEV50 casings mean in addition to prodding them for tech data they seem reluctant to hand over

Regards
Alan

Hi Hank

This is my unit. Slightly different to yours but I would guess they both operate the same way.

Hi Rush are you still on the forum. I was searching for any other Trinis and only found you.

Hello.
I would also like the software from mppSolar: "communication assistant.exe".
Please, can you send it by email: drobotaromeo@gmail.com ?
thanks

Hi, I hope you are doing great. I am phD scholar from Edinburgh University UK, I need second life lithium ion battery data pack (not cell data), including aging data (capacity. nominal voltage,SOC, number of cycles, internal resistance, ambient temperature etc). I am simulating an energy storage system in Simulink comprising of grid, second life EV battery and PV array. Can you please guide me in this regard. Regards

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

Hello
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

Hi! I think we spoke about these LG batteries a while back. Are you using them in your off-grid storage? JH3

Welcome to my single highest commenter on YouTube!

I work on tons of battery related projects in my free time. This website is awesome for figuring out what cells I have!
