Battery Questions: pros and cons

2256 Views 26 Replies 6 Participants Last post by  237
Okay, I have been looking for an EV that is a full size SUV. We have 5 kids still at home and this is the first one that checks all the boxes. (Besides Rivian R1S that may be 2 or more years and 2x the price) I just can’t believe I haven’t come across Vinfast until now.

The battery lease is not a bad thing but raises 2 thoughts:

1. With them replacing the battery at 70% degradation then do we not have to worry about charging closer to 100% every night if we want? I mean if they will replace it why not push the battery more each charge?

2. The federal tax credit is based on how big the battery is that you purchase on the EV. But if you are not purchasing a battery are you not eligible for a tax credit?

sorry if these have been discussed, I am new here and don’t see a huge amount of people in this forum.

First, you are not paying for the initial battery which make the vehicle cheaper.
Thats valid.

But I’m still not impressed with how they act right now.
Nevertheless I’m mad that there is only one plan at the moment
certainly a plan with higher limited mileage would have been a better choice. MY take away is the first one was far too limited. Even for a 24 mile round daily trip it wasn't enough. Also a bit irked that they don't tell us. One of the 'benefits' of being a vinfirst/vinpioneer was supposedly we were supposed to get news 'first hand'. So far, haven't seen any of that yet. One has to visit the web site daily and really pay attention for any changes.

You are aware the mileage estimates aren't the US based ones; so count on the range being lower in reality.

Yeah, rivians are nice if you like spending that much $$$$. Not me, that's what drove my decision for a vinfast; much cheaper.

yes Im totally aware that they’re working with WLTP standard and Im also aware that for the majority of cars this range number is larger for the US than if tested with EPA standard.

What Im talking about is: I‘m curious if they will lower their official WLTP numbers … Let’s say that the VF8 eco suddenly is WLTP 270 mi instead of right now 292 mi or the VF9 is suddenly WLTP 340 mi instead of 369 mi.

I've already prepared myself the range will be 15% lower than stated. All good if we stay over 200, I'm not worried. We take a rare longer drive will take the ugly Prius. 🤮

I've also already decided on the VF8 plus and bigger battery.

I agree, luckily for me I am not in California so I am not going to get a VF9 right away, I love following the company to see how they play in the California market first. Then in 1-3 years when we are may be eligible to purchase here I can see how they are doing. But I agree, they are a little too quite and unorganized for how far along they are.

CATL and VinFast reach Global Strategic Cooperation to promote global e-mobility


On the strategic side regarding cooperations VF seems to do some really smart decisions. Especially the skateboard thing sounds to me like it could be a huge thing for future models and model years. For my VF9 reservation to late but nevertheless: kudos!
