Yes yes yes, do part two video install with battery profile reprogramming. Really thinking about doing this swap on both of my i3's but did not know how to go about it. This is such a blessing to learn from others doing the same thing. Thank you so much!!!!
That's great news! Can you share what brand of battery you installed? It may be important as to the differences in the BMS's used and their configurations. Thanks for the comment.
@@bmwi3diy782 $79 back then, was the best price/size I can find. Terminals need to mod or adapter to fit, factory bracket can be used but don't tight all the way as it would crush the bigger battery. My car is charging it at 14.6v, might be a bit high for this battery, but so far seems okay.
The confusion is you can discharge the battery below freezing but, you should not charge the battery below. So, the operating temperature range is what the battery manufacturer is referring to.
Great info! Very timely for me, intending to replace my 12V battery soon as I’ve had a couple problems with the positive safety terminal fuse blowing. Putting it down to an aged battery (about 8 years old)
In my experience, lots of problems with the cold (even just -10C), self-heating batteries don't help as during the heating it cuts off supply to the i3 making the alarm trigger etc
Interesting! I wasn't aware that the self heating batteries cut off the external power. I haven't installed the battery reviewed due to the issues mentioned, yet several viewers have apparently installed other vendor's batteries with at least some success. My i3 was charging the AGM battery today at over 15.2V, which would normally cause a LIFePO4 BMS to disconnect for an overvoltage condition. I'm not sure how the other viewers are addressing this (or they're not?).
LiFePo4 batteries should not be charged below 32 F. You will damage the battery. You can buy LiFePo4 batteries with low temperature charging but, I have not seen one for such a small Ah size.
So, you found a very cheap chinese battery on amazon and you made a video promoting it as an affiliate ? An i3 owner would be better off contacting a battery builder in the USA ; LithiumMoto as an example, to get a lithium replacement.
Thanks for the comment! If you watch the video, I highlight several issues with the battery reviewed and using a lithium starter battery in this car due to the EME charging characteristics (over 15V in cold weather), the issue with the BMS high voltage (14.1V) disconnect of the battery with potential of load related voltage spikes on the EME, and the low temperature charging limitation. Also I highlighted that at least one US manufacturer that makes lithium replacement batteries for Tesla's does not make or support a battery for the I3. Please watch the video and I am interested in any suppliers you know that have solved the issues mentioned (it is not clear that LithiumMoto has a viable solution either from their website -without more info). Meanwhile, I have not installed this battery because of these issues. I did install it into an electric lawnmower in the meantime, working great for that application!
NOCO Lithium NLP20, Group 20 - installed this guy off amazon. Has Battery Management on board and according to the manufacturer..the charge volt range is congruent with I3 converter
Thanks for the information! Update: I inquired with the NOCO customer service, here is the response I got: ====== "Thank you for contacting NOCO support. Unfortunately, the NLP will not be compatible with this vehicle. It is designed for smaller power-sports vehicles such as UTVs and Jetskis. Additionally, a 15V alternator would be incompatible with the NLP line. If you have any other questions, please let me know and I would be happy to assist you. Thank you! ====== Based on this, I would be cautious/ not recommend regarding the installation unless the maximum charging voltage on the i3 can be reduced (can go as high as 15.2+ volts in cold weather). It may be possible to reprogram battery type using bimmercode, but I haven't tried this yet.
I am in Florida so no "cold weather". We did get some 30s for a day or two..no issues. I have both Bummer code and Bimmerlink. I did reset to new. Do you think I should monitor/test direct or indirectly?
hello bmwi3diy..... may i please have a email/contact info to chat with you about a battery that i found. i think it addressmany if not all of the concerns from this video. look forward to your reply. blessing rich
Sure- I'm interested in any new 12V battery information that you have, since the one in the video was not, in my opinion, sufficient to install in the car. I has worked great in my old 1990's vintage battery powered lawn mower. Contact Info: bmwi3diy@gmail.com

I've replaced my 2017 i3 with a 10AH LFP, and used for 2 month now, no issues what's so ever, the best investment for i3!

Is 10 ah enough, I put in an underpowered LIFEPO (MOTORCYCLE?) in my Fiat 500e, it died on the freeway
@@rp9674 Has been used for more than an year now, so far so good
I did the lipo battery install on my 2019 1 month ago, going strong and no errors
Nice. Can you share the particular brand of battery used? Thanks for the feedback!

If you live in a cold area, maybe a styro layer around the battery would help
AGM are unimpressive to me

I agree. This battery's literature on Amazon said it could charge
