Yeah, thanks, that seems good! The first post I saw has a towbar.

Yeah seems the right way of thinking. The kWh is your Diesel. For 10L of Diesel or for 20kWh you can drive 100km. Tiny cars might take a bit less, you will figure it out when you have yours and how it will perform with your driving style. Maybe you drive slowly, then you can do 100km with 12kWh or 7L of Diesel. And solar on your house is just the next logic step. Because you want free Diesel.

Have you played with LiFePo4, especially the bigger cells, and brand new cells? You might be surprised how lightweight and how much less volume they have, compared to the same capacity as lead acid . My guess is that the same weight of LiFePo4 would give you maybe 4times the range of lead. The reason is that with LiFePo4 you can really use 80% of the capacity where lead will be destroyed very fast if you do this too often. What you might wish to stay away from is second hand LiFePo4 from Aliexpress or Lazada. These cells are half dead and each cell is different from the others, resulting in need for heavy balancing. But new CATL or similar brand cells directly from China are a good option and the price has dropped significantly. If the vehicle can run on lead acid, it can run on LiFePo4. With double the capacity of the LiFePo4 (because they are smaller and weigh only half) , your current draw would not stress these cells to a level where cooling is required. If this was the case, then your lead acid would already be boiling.

Yeah this is very cruel to take dogs instead of horses 🙂 . You should go electric LOL

Does this have a LiFePo4 battery? What specs do they provide for it? How long does it charge and what type of charger do you have?

No subsidy, but they can provide a pickup for under 1M. I expected people to jump on any electric pickup, but this seems not the case. Diesel seems still too cheap at 40B and a pickup only takes 10L/100km LOL. I suppose the BYD shark will also not be produced in TH.

Seems ok for short trips. How is this seen legally by the Thai? Is this the same like these motorbike tricycles which are kind of illegal but nobody cares? There however I assume that most of them have an insurance for the motorbike.

Yeah this is what wife says, can just let them deliver the stuff. Therefore the little digger... gives a reason for the Pickup 🙂 By the way, the excavator in the picture is also electric. 60k B , but they want 160kB delivery from China LOL.

Yeah, actually this gives a good reason to buy the Riddara. The aim is to get half a palette of concrete blocks and some cement, 2m solar panels etc. from time to time. A trailer would be nice here. Also I feel the need for one of these little diggers. They weigh from 550kg + . Let's hope 2025 is as bad for EV as the previous year, with another big round of price cuts.

Does anyone have seen or heard about tow bars for trailers on any of the more budget like EVs? I know that the Thai don't use trailers that much, but maybe some rural area guy would have this? Most likely the BYD shark would have this option, but even the Riddara pickup would still be at the very upper end of my budget. Therefore the most reasonable option for me would be some Neta, Dolphin or so with a tow bar and a trailer which I would bring from europe.

If these knife switches are not to your liking, you could use any type of switch, however not directly to switch the motor, because these little ones would just burn away at the first switch off when an arc is created because of the DC. If you want tiny switches like this, you would need some electronics like big 200V mosfet transistors to do the switching. These electronics, would go into a little box and the tiny switch outside is basically giving only a signal to the electronics. With inductive loads like pump motors, the electronics quickly become complicated because they need to be protected against voltage spikes produced at turn off. I'm not sure if anything of this type is available commercially at a reasonable price.

The original switch looks solid for 12A DC at 72V. Maybe you could also say what type of switch you would prefer for your wife. Maybe you like a push button, then you can have it, but need a kind of solid state relay in a little box.

I have the same question as carlyai. But you guys in the EV forum are always so focused on cars rather than electrical questions ... May I ask what is the reason you kept the car charger on single phase? I'm thinking of a car port the style Crossy has built. So seeing these 3 phase inverters now being not much more expensive than single phase, I thought this has advantages if you parallel 2-3 of them. The currents on the AC side would be in a region I'm comfortable with, where with 10+ kW on single phase seems already a bit high for me.

It looks nice, until the point where he shows the voltages of the cells. 500mV difference I would not really want in my battery pack. And yeah, you can balance them, just to see them drift away again at each charge and discharge... On top of this, these cells are LiPo chemistry or similar. For the price you can get new LiFepo4 cells, thermic recycling for these MG cells would probably be the best option. In the worst case, these unmatched cells will initiate their own thermic recycling inside your home.

OMG, these things look like even uglier copies of SSangyong Rhodius. Any european would buy this?
