Understanding Used Tesla Model S Batteries 

Tesla Model S Batteries are Used Lithium-Ion batteries that are based around 444 Panasonic NCR18650B cells running in a configuration of 6s74p. These batteries have been pulled from wrecked Tesla Vehicles. 

Do you provide a warranty on Used Tesla Batteries? 

We don't provide a warranty on Used Batteries due to the uncertainty of how these batteries were maintained and what their current SOH (State of Health) is. We verify a healthy resting voltage is present on each of the series connections. If you would like a more comprehensive overview we do offer capacity testing for $225/ module which will let you know what the SOH of the batteries are and their capacity at C/3.  This is more valuable information than the year and miles of the vehicle that the batteries were removed from since it represents the true usable capacity of the battery devoid of any assumptions. 

How much battery life do these modules have left?

We cannot provide any estimations on the remaining life of these batteries. The only information we are given when purchasing Used Tesla Model S batteries is the mileage, normally these batteries have around 50,000 miles. 

Total cycles measured in miles is only one variable needed to determine the battery SOH.  One should also consider how the batteries were charged. Trickle Charging refers to charging a fully charged battery at a rate equal to its self-discharge rate, thus enabling the battery to remain at its fully charged level. Fast Charging refers to using a rapid charger that is much faster than your average electric vehicle charger. When charging and discharging your batteries the internal resistance in each cell creates heat. Fast charging creates a lot of heat that has the potential to shorten the life of your battery, slow charging/ trickle charging means less heat and potentially a healthier battery long term. 

The key takeaway is that mileage alone provides very little information about the actual battery state of health. The only way to understand the actual SOC of a battery is to load test it at an appropriate C-rate (rate of time in which it takes to charge or discharge) and to measure the current over time. 

We have seen modules with 50,000 miles perform worse than modules with 80,000 miles likely because of some of the variables listed above.   

Do you provide load testing/ capacity testing?

Yes, we provide load testing/ capacity testing at a rate of $225.00 per Tesla Model S Battery.

Can I connect my Tesla Model S Batteries in parallel?

Yes, however, you should consider that in doing so your system will consist of parallel strings. Please read the attached documentation that explains parallel strings in more detail. If parallel strings are present it is absolutely necessary to use a battery management system per parallel string in a master/slave configuration to ensure that each parallel string is being properly protected.

Can I use Used Tesla Model S Batteries in my electric vehicle conversion? 

This comes down to the actual application but in short, the answer is typically yes.  The only variable that will affect its applicability is the measured SOH.  Any battery with a SOH below 70% is considered unsafe for high C-rate automotive applications and should be used exclusively for stationary storage applications.  

Do I need a Battery Management System if I keep the Original Tesla BMS Boards?

The Original Tesla BMS Boards require the Master Tesla BMS board to protect the batteries. The original BMS boards alone can only monitor and balance the cells. Communication with the original BMS boards is mostly experimental and not fully tested. These units are not readily available or properly understood. We recommend using the Tesla BMS Boards from our EVolve Electrics store. These units can be easily installed and are compatible with the Orion BMS to ensure that your batteries are properly protected. Click here to learn more about the Orion BMS. 

Can I discharge my batteries down to 0%?

It’s not recommended to discharge your Tesla Model S Batteries to 0%, this would negatively impact your battery SOH. Tesla Model S Batteries should not be discharged below 20% SOC (State of Charge).
