yes, an R80. trying to confirm years for the 3.0 and 3.1 packs and mAh rating on the cells. based on the 214 Ah cited above, that’s 3100 mAh per cell. To be honest, anything less than the 3300 mAh cells being used in the 75/90/100 kWh packs in the Model S definitely feels like a lunch bag...

some quick notes here: some components may be as much as 10 years old, many are not. More importantly, all pack components are vefieid to factory spec and every pack is rated and certified for range and capacity.

Do Your Homework With These 3 Simple Questions In the event that you are shopping around for a reputable service pro to fix or replace an ailing battery pack, be sure to ask these 3 simple questions: 1) Can you provide me with full brick level capacity diagnostics? And if not, how do you...

sorry we missed this earlier we absolutely do 60 packs - in fact, we’re one of the few that can actually specialize in them. 8f send us a request, we’ll pull together an estimate in no time www.recell-ev.com/contact-us we’ll also take a closer look at that web link error. we’ve just done...

So the original R80s were delivered with 3100 mAh cells?? and with Vnom of 358V that’s only 76.6 kWh… or were they simply marketed as 3.0 and not actually as R80s? whereas the second generation 3.0 (ahem 3.1) we’re marketed at R80s with 3200+ mAh cells??

@WillNTO, while we’ll never turn owners away, we expect to produce these packs, DC fast charging, etc. on a very limited basis, with a view to producing a bespoke performance restomod probably north of $185k, plus the donor car. That may not be much comfort for most owners. @WillNTO, you and...

@ViperDoc, as you know, the technical implementation for DC charging is solvable. We are watching closely as the NCAS standardization rolls out and Tesla’s next steps on the Supercharging front play out. As folks know, there’s been a lot of change going on in the fast charging world in the 9-12...

full details on pricing, specs, etc. are on our website www.recell-ev.com/roadster

and to be clear, we’re not here spiking the ball regarding any demise of the R80. Despite the bloat of the R80s, Tesla is far better situated to produce these packs. Barring some unexpected development, we expect to produce only a handful of Roadster packs, at best.

And as for our technical view of the R80, we’ve had this to offer. In short, a Lightweight Performance Pack, DC Fast Charging and possibly Water Cooling are the winning trifecta for Roadster longevity. Regardless of whether the R80’s days are numbered, Roadster owners are betting on the wrong...

We posted this last week ——— With even further headcount cuts in store, not hard to connect the dots on the future of the R80 packs when Tesla’a flagship Superchargers are being spun off. Even less comforting considering people on this forum and their families may be affected ——- quite...

We’re always happy to help owners get to the bottom of things.

given the deltas involved you're unlikely to be able to reset it - or rather, it’s sufficiently out of balance that that the imbalance threshold (vs. a weak short alert) is capping your charge (or soon will). As a technical note, the imbalance alert can't be reset, it's based on the balance...

Folks should also know that the few repairs we have provided to date have ranged from $4,995-$7,495 - parts, labor, shipping and taxes included - depending on the size of the pack. Some owners of course choose to drive their cars home, others choose the convenience of having it shipped back...

Please note that we respect the privacy of all our customers and have a long standing policy on not sharing details on any services or communications that we may have provide to them. That policy remains in effect. We can however share our policy that any/all repairs on 3rd party battery packs...

this pack has been sitting a VERY long time, so needn't be a weak short u029 bleed out. However barring some rapid turnaround and some serious, serious balance charging - possibly weeks or months worth - we suspect it's in, or soon will, be in the u018 territory. @glhs272, we definitely want...

@Erik we can absolutely help you out and run the remote diagnostics for you, free of charge, no obligation. simply go to our website to submit a request www.recell-ev.com/contact-us

important clarification. we’ve said module matching can work, but it’s not especially sustainable. 18-24 months is the max we’ve seen it last, and you’ve absolutely got to nail the module match. the far more durable approach is to reconfigure the pack into a 70/350 or 75/350 it’s one thing to...

also, it will not report on whether any alerts have been triggered and reset

Toolbox accesses Tesla’s server-side logs for any historical data.

While a device may still be present - hopefully not, if it's continuously resetting an alert - it's probably not likely to be if there's some kind of scam afoot. And if it's not, what then? Still doesn't mean that an alert hasn't been reset previously. The real key is the ability to view the...

absolutely. and better yet get a PPI done by a qualified service tech. 👍

yes. we’ve come across these devices several times now… this one came from a car that left the owner stranded in the middle of nowhere West Texas. no buttons for user intervention, so when left plugged in, the device will continue to auto-reset the u029, based on some undisclosed criteria. 😮...

There was a lot going on during that period - Brick 6 failures on the BMBs, weak short issues starting to emerge (beyond simply pack imbalances), sudden rash of fires, etc. whether it’s THE factor behind the reduced supercharging rates, unclear. but surely reduced supercharging rates would...

we obviously can't speak to any of that - we're simply showing the diagnostics and how this is all available in Toolbox 3. Beyond even the weak short alerts being thrown by the BMS -- 33 in total! 😮, the real tell for any prospective buyer is the charge limiting behavior in the Max Voltage...

So... We recently had a very interesting situation arise with an out of balance pack that came in with a BMS_u018 imbalance alert and a voltage delta of 120 mV. Pretty standard stuff and we go to work. Problem was that when we ran the full diagnostics, the CAC was pretty much even across the...

unfortunately, a u029 won’t run indefinitely. it may run for some time - weeks/months - but the reason the alert has been trigger is that the pack is self-discharging. either rapidly in the case of one rogue cell, or more slowly in the case of a collection of several aging and defective cells...

we intentionally avoid any supercharging mods. full stop. for exactly the same reason(s) cited by @wk057 - the risk-reward/ROI just isn’t there. and, we understand if your a road warrior and power user. power users buy power tools. 😉

we always recommend taking a snapshot at the 80% level. you can get some fairly large divergence out at the ends of the curve. (not to suggest that 100 mV just disappears, but 80% gives you a much more reliable view of the actual delta)

@wk057 worth a read/watch. while technically 'feasible', we have probably the same questions you might... not the least of which is why?? and to what end?? while admittedly the economics in some markets may support this, but all this - along with the inherent risks - to maybe recapture 1%-3%...

We suggest grabbing some paper with the pack layout, and maybe some cut outs for the modules. It's a bit like a game of musical chairs with the #8 and #9 chairs now removed. We're not trying be obtuse (honest), it's a worthwhile exercise. 👍

the vNext network jumpers for our RC 210+ packs have arrived! Super clean, plug’n play! Some background: this connector allows the BMS to bypass Module 8 and 9 in the network string of a Model S battery pack. A simple, but critical piece in converting a 400V / 16-module pack to a 350V...

We'll need to do a bit more digging there, but yes 👍

They are as follows: 60 kWh - 204.3 Ah 70 kWh - 232.4 Ah 85 kWh - 232.4 Ah And nominal voltage for State of Energy for these packs (note this is different from State of Charge) are 304V and 347.4V respectively We will pull the others for 75/90/100 kWh packs

the BMS restore functions in Toolbox require like board for like board. it appears the donor board is a 79 and the backup is an 89? if so, the donor board needs to be an 89 board to write the 89 backup to it - the best way to achieve this is probably to match part numbers and revisions, since...

yes, several, and tested extensively in our Mobile Lab - a 2014 Model S, more affectionally known to the team as 'The Ocho'. We now have several 'skateboards' (i.e test chassis) with packs in regular rotation.

To date, we haven't had any of our RC series packs fail from capacity issues. isolation faults (2) are for sure the trickiest to guard against and we've had one unexplained failure related to a phantom misread from the current shunt (super rare and nothing you can guard against there. pack...

what's surprising to us is how few shops understand the actual fundamentals behind pack balance and module capacity. sometimes you'll see posts from otherwise reliable sources suggesting that all you need to do to swap and balance a module is a digital voltmeter - just match the voltages and...

here’s another textbook example of a CAC imbalance that we had in just the other day. As you can see, the pack is 8.2 Ah out of balance and the voltage delta of 100 mV is floating in and out of the ‘red zone’ - throwing a BMS_u018 as the pack is discharged and then clearing as the pack is...

and just for some additional background on what we do at Recell: all our packs are balanced and certified to within 2%, and often within 1%. That’s our standard for pack certification. Case in point, by removing the failed module in the pack shown above and converting it to a 350V 14-module...

Invariably when discussion turns to a failing battery pack, the topic of module swapping comes up, so we thought it would be a good time to talk about CAC - Calculated Average Capacity - and why it's important. In fact, if your talking to a shop about pack replacement/repair and they’re unable...

we never swap modules in any of our certified packs. it's not a judgement on swapping methodology per se (see note below), and certainly not a scare or sales tactic, we just don't have to with our remanufactured packs. all our certified packs contain factory-original modules, sitting...

the same level of information currently available to Service Center technicians. ie, more than most publicly available tools, but not everything.

No special equipment. All that's needed is the vehicle's VIN and the email linked to your VIN/Tesla account so that Tesla can send you an approval request to allow remote access. Be sure to double check you have the right email that's linked to your Tesla account. Note, for obvious privacy...

Free Diagnostics - time is of the essence when it comes to a ‘Maximum Charge Level Reduced’ alert. Knowing how severe the issue is and how much it will impact your driving range is a BIG deal. Recell will now provide FREE no obligation remote diagnostics if you have a ‘Max Charge Level...

Hi @karkrazy, with regards to drive units we currently don’t do many of these, maybe 1-2 per year. When we do, it's usually the result of some issue that has come up while trying to resolve some kind of isolation issue with the High Voltage Bus. It's not really our mainstay. know that's...

Community members, we can't express enough how important it is to avoid the number of oh-so-tantalizing, yet risky BMS_u029 reset options that are out there. We had a BMS_u018 pack in this week that was significantly, but not wildly out of balance - 200 mV. Pretty standard fare for a BMS_u018 -...

indeed, we were simply outlining our criteria for certifying a refurbished pack. 👍👍

8Ah is a 3.5% capacity delta. would like to see better of course, but hardly fatal and will provide reliable operation, provided it remains stable.

An important bit of background on our extended warranty program Our extended warranty has always been contingent on the condition and capacity of your existing pack. However, despite our goal of offering an all-inclusive warranty with additional core credit for owners with low mileage packs, we...
