But bummer , Car stopped 10km from home , One dell drained out real fast whilst all the others are still healthy.
$160 tow truck ride thank you very much.

Ive charged it back overnight & Ive been hammering the car this morning, It really flies when your "trying" to drain the battery , I usually drive for economy !! The cell is looking good , maybe it drops off fast one below a trigger voltage. Anyway I do have a spare cell as I was originally going to use 46 but could only get 45 to fit. But I have to pull the seat box to change it.

I'll just monitor it for now & see if it really is a bad cell or just a random event.

Here is the BMS window, you can see the bad cell represented by the short stick !! Flat is 2.4 which it got to, bat had recovered some by the time I took the photo. I charge them to 3.45 so most of the other cells look pretty good.

(I really want to avoid having to buy a 5Kva generator ??)

Why not take a petrol generator with you?
Or its a stupid idea....

Cheers

Brilliant job! Now add a solar array & hit the Simpson Desert like the zook did.

Do these batteries need to be 'equalised' on install ?

yes, they were all balanced at 3.30V but I find now that they needed to be balanced at the bottom of their charge cycle at around 2.7 - 2.8V I can take them all out & do it but Ive come rot terms with how the batteries act, The Zeva BMS balances them as they charge, until about 3.45V when one battery starts going high the BMS shunt resistor cant cope with that.

If I had one, I would bring it , But I need a bigun The Onboard charger is 3.3kw so I need at least a 4KVa , or 2 x 2KVa might work .

WOO HOO, E-Series Passes VASS inspection , the Inspector said it was better than some commercial conversions he has seen.

I just need to install an Inertia switch as found on a Td5 Defender Firewall (anybody got a spare) and get my charge lead test and tagged .

I had to put radials on it too (for the brake testing) , so got some Kumho 225/75R16 & wow , what difference , It will almost roll an extra 15-20km per tank. Looks don't suit but hey , I can still put the cross plies on any time.

Great news!

I can't help but giggle a bit at the test and tagged lead though - not sure how that makes the vehicle unsafe to be on the road. 😉

I don’t believe there is any legislation or regulation requiring it for domestic use.

There's actually very little around test and tag for anything. Most buisnesses do it because it's best practice and anyone involved on the construction or mining industy do it because it's a site requirement. There are some requirements depeding on industy and equipment type but not nearly as much as you'd imagine given that everyone seems to insist on it.

I carry a set of tags everywhere I go with an old Meggar. Happy to relieve people of their money to do it if they want it done, even when not nessesary... 😉👍

Agreed, but for something so simple I did not want to argue if it means having the conversion signed off. I think its more an expectation if I use my charge cord plugged into some OHS savvy workplace power point.

There is nothing even mentioned in the relevant VSB / NCOP 14 about having the 240v circuit certified, only that whilst the vehicle is on charge its traction circuit is disabled.
