Autosleeper Nuevo Lithium upgrade

I have a 2022 Autsleeper Nuevo EK which came with a 60ah lithium battery. I have purchased a Fogstar 105ah lithium battery and on Monday am going to swap the 60ah out. The precautions I have taken are: 

1. Marquis (MQ) have advised that it is ok 
   
2. You can get an upgrade to 100ah AS lithium at purchase, so assume it is ok
   
3. Charge profile should be good as I am swapping Lithium for Lithium 
   
4. Fogstar have advised it is OK, lift and drop new one in 
   
5. I have been advised that I have a MPPT controller installed but not b2b 
   
6. I believe I am with Amp tolerance on cable 
   
7. Sargent say speak to MQ!
   
8. The Fogstar has BMS for protection including heat pad 
   
9. I will isolate Sargent ECU and take out fuse b before swap out 
   
10. I am changing the terminal connectors from m6 to M8 
    

Is there any other precaution or something that I have missed before going ahead?

Regards,

If you are using the tracker before you disconnect the battery you will need to go into AS Monitor and put it in service mode otherwise you will get a call from Sargent. As yours is the same year as mine you should have a smart alternator, if so best to fit a B to B, not sure you will have a mppt controller mine came with a pwm which was rubbish. Also you might need a software update to the Sargent system to switch off the split charge if you fit the B to B.

Any idea where I can see if I have a B2B installed?

I work in an electric bike shop and we have to do a whole article about the misinformation that is going around about batteries largely stirred up by the Daily Mail. I can tell the battery that you are referring to is an unregulated Chinese nock off, unlike the Bosch system which has no recorded fire incidents.

Isolate solar panels before disconnecting the battery and connect the battery before reconnecting the solar panel

Am I not doing that by pulling the fuse next to the battery?

A lot of electric cars don't have Chinese knock off batteries but still catch fire.......

You have to isolate the panels from the regulator first before removing the battery and when ready to reconnect, reconnect the battery first. Then reconnect the regulator

This is so that the regulator doesn’t take the voltage from the panels and try to charge your battery at plus 17 volt plus ( or what ever your panel vmp voltage is ) when you reconnect the battery and boil your batteries

Is the same achieved by covering the solar panel?

Define what you mean by a lot? And compared to what ICE fires? I had a Renault Clio, the fuel tank under the back seat split with strong smell of petrol everywhere (under where the kids sat). Admittedly there was a 0.0001% Tesla battery failure / fire risk at the start, however they seemed to have sorted that out. How many accidents / incidents have happened with lead acid as an example? As they used to say at work, everything needs to be taken in context, something that political parties make bad use of.

Yes

Of course - such is the state of anti-EV press in the UK that "everyone knows" that a "lot" of electric cars catch fire.

But when you take an independent look at it, the actual facts (in terms of real recorded fires) show that petrol and diesel engined vehicles are far more likely to catch fire than EVs. Here's a reference to a report from a Swedish gov't agency that shows they are ~19 times less likely to catch fire than cars that use hydrocarbon for fuel:

https://www.warpnews.org/transportation/electric-cars-catch-fire-less-often-than-fossil-fuel-cars/

Similar studies in the US have shown an even greater ratio - though of course it's complicated by the fact that the average age of an EV (in the US or anywhere else) is likely to be a fair bit younger than the average age of a petrol or diesel-engined car.

Such is the state of the anti-EV press that when the recent fire broke out off the Dutch coast on the Fremantle Highway car carrier, the immediate press reports spoke of electric cars being on board. The subsequent investigation showed that none of the electric cars were involved in any major way (they were apparently further down the ship than the seat of the fire).

As I understand it, companies with a vested interest have large budgets to spend "promoting" the "dangers" of EVs, so don't expect to read a fair analysis of anything about EVs in the main UK press right now.
