10$ ea. Tested, IR, clean, capacity, photo. Very low IR. Best price you will find. Guaranteed free replacement if customer is not satisfied. I can do that, I have the buying power, suppliers, and stand by my work. 100% Feedback.
Many available. 100+
Inquire within. Full built batteries, lipo packs.... also available. Time and material is typically how I estimate the cost of a build. I have references ( peers here, and other places) that would vouch for my integrity as a builder/seller. I also have an eBay store for feedback inquiry.
I will update this thread with more specifics. Be free to leave comment or inquiry. I will also be posting true torture tests, of these cells.
Note : This cell is VERY powerful, and you ( buyer ) must USE AT YOUR OWN risk. Made to be a safer cell in production, the current availability of this cell is int he THOUSANDS of amps. Very safe, but not for beginning builder or those not well versed in Lipo care and handling. I will NOT cater to a novice, or awnser a million questions such as " How do I charge them?" or " Do I need a BMS?". If you wish to buy these cells, you already know what they are, and know how to use them with respect. I cannot cater to everyone's questions, the answers can be found here on the forum. These cells laugh at the 10Kw + of a powerful ebike... and last for years.
Chevrolet Volt Lipo cell.
The Volt cell (LGX P1 and other revisions) is a 383g high power ( not high energy density ) PHEV cell of 150Wh/Kg and 300 Wh/L. They were ( are ) rated at over 10C continuous duty, with temperature increase beginning at 4C.
Cathode.... is mixed spinel LiMn2O4 (LMO) and layered LiNi1/3Mn1/3Co1/3O2 (NMC). They have a mixed graphite and amorphous carbon Anode...They are very advanced, mature, and well known cell design and form factor. Internal resistance of 1.75mOh in the first revisions to 1mOh in the later revisions.
NASA was studding them 10+ years ago. They were more expensive than the others at the time and throughout production. They were safer. they were extensively tested by the NHTSA, pre-production of the Volt. EV West has offered this very cell for the buyers of their high power EV packages.. for 3x the price.
PHEV cells, which these are, are power cells. Which means their engineering emphasis lies on delivering high power instead of having a big wh per kg/energy ratio. This is because in PHEV the batterypack is relatively small compared to full electric vehicles but it still needs high power delivery capability to propel the mass of the car. These LG Chem cells are about 150 Wh/Kg. In contrast modern Tesla Model S cells (NCA) are energy cells with 250 Wh / Kg. This doesn't mean they are better, but they are different. Those Tesla cells don't offer very high C rating for example but rely on the packs cell masses for the super high ludicrous 1500 A current delivery.
In the Volt cells, is the separator material, and a less volatile and more tolerant electrolyte solution that doesn't settle or migrate with temp swings (part of why they are more expensive). The maximum temperature before venting is 160*C. They also were pushing self-healing ... so the electrolyte will recombine under some conditions minimizing swelling. The goal was 5000+ cycles for production, and the cells were warranted for 8 years or 80K mile.
The MSDS is available ( for shipping)... but the full datasheet is hard to find. NDA must be signed and you must be a representative for LG. You have to be an authorized integrator for them to share with you, paired with a stack of NDAs. Similar, but not the exact. The MSDS states the cell is not combustible. The same cells are also used for example in Opel Ampera/Xolvo/Renault Zoe packs of the era.
