the math is 24×14.8×180 = 63936 i.e. 63.9kWH, IF using the No.HY-4S1P180 "63.9Kwh CATL 14.8V 180ah 4S1P NMC Rechargeable Lithium Ion Battery Module Electric Car Battery Pack For Nissan leaf car EV Power Batteries ", you would need 24 blocks and figure out how to fit them all into the old battery shell/case.

OK, let us calculate a little bit: Let us start with 8s1p battery: It has - according to the description on it - 29,6 V x 90 Ah x 12 pcs = 32 kWh (approx.) - it may be seen as quite good as the replacement for 2016 30kWh Nissan Leaf original battery. BUT: 12 modules x 29,6V = 355 Volts. This is to low voltage for Nissan Leaf! Nissan Leaf battery has about 395 V when fully charged to 100% capacity; about 380 V when charged to most often used 80% capacity and about 365 when discharged to about 50%. How will battery management of Nissan Leaf deal with the 355 V voltage?? Let us go on with 6s1p battery: 21,9v x 92Ah x 16 pcs = 32 kWh (a little bit more) - it may be seen as quite good as the replacement for 2016 30kWh Nissan Leaf original battery too. BUT: 16 modules x 21,9 V = 350 Volts only! Again: this voltage is much lower than the typical voltage of the standard industrial Nissan Leaf battery. The same question as by 8s1p? How will battery management of Nissan Leaf deal with the 355 V voltage?? I ask you kindly for PRECISE TECHNICAL answer, not marketing related statements. Thank you.
The voltages being used in this video are nominal voltages, not "fully charged" voltages, which are totally different metrics. Using nominal voltage (and not "fully charged" voltage) is considered the industry standard way to rate battery cells. These are NMC cells, very similar in chemistry to those used in the LEAF, and have a nominal voltage of 3.7v, and a fully charged voltage of 4.2v (the same voltage as those used in the LEAF). The LEAF in factory configuration uses a 96s battery pack, with a *nominal* voltage of 355v. When fully charged to ~4.12v/cell, you get nearly 400v. This same measurement methodology applies to all lithium ion cells, and would be essentially the same voltage as any other 96s setup using traditional NMC or NCA li-ion cells (obviously LFP or LTO would be quite different).
@@Alex_Bessinger Thank you very much for you kind reply. There are the NMC cells used in both the battery packs? Or is the 8s1p pack with some other chemistry? Where can be your batteries bought in Europe? Are there some distributors with technical knowledge and replacement praxis in some EU country? Thank you.
@mirektrmac2773 I'm not the poster of the video... Just wanted to point out that the voltages they are quoting are nominal, and not "max". Based on looking at their website, it looks like all of the modules in this video are NMC, but they do have other chemistries available. It would be quite difficult to use anything other than NMC or NCA for a LEAF battery, as the Battery Management System would not be compatible with anything that uses a different voltage range (such as LFP).
It's all nice and good, but I don't care about size and the S/P arrangement of an individual battery. Tell me precisely what to buy, everything, all support hardware, all bits and pieces to build a working pack. It is _not_ useful to an individual, not expert customer this way. Tell me what to buy to build a full pack, and make it _easy_ for me.

Do you have plan to make modules for tesla s battery,......
Do you know of any online reviews of your LEAF battery packs yet?
Can you provide detailed instructions on how to make this work with the leaf’s BMS?
the math is 24×14.8×180 = 63936 i.e. 63.9kWH, IF using the No.HY-4S1P180 "63.9Kwh CATL 14.8V 180ah 4S1P NMC Rechargeable Lithium Ion Battery Module Electric Car Battery Pack For Nissan leaf car EV Power Batteries ", you would need 24 blocks and figure out how to fit them all into the old battery shell/case.
would u offer custom voltages/kwh packs in future using sodium instead of lithium?

Very soon everyone wants to swap the old aging hybrid battery cells to LFP cells..

Cost Battery for Nissan leaf 2013?
yes, now best price can make less USD2000 per set
How much is the shipping cost to say New Zealand, Auckland?
@@ffyy88 we can do CFR to your sea port, about $400
Cost please
That's great! When and where can I order?
