- We have made a little mistake... and we fixed it!
Also we did a test how the Twizy performed with the new battery cells.

Excellent work. That's a great improvement in range since upgrading it's battery.
do you have any website to share your research please. it can be help full. superjob I plan to do the same with my twizy too
Can't wait for the next video!
Well done. Like it. She's the Twizy have a balancer and did you top balance the cells before assembling them?
Hi, I'm surprised by the Twizy's short range with this new battery. The original battery has a capacity of 6kWh and yours almost twice that, but you still only manage 80km.
That is what I thought. A friend of mine did the Finland battery and he is doeing in Winter 130km range and almost 180ikm in winter. Look like your China batteries are not really 11kWh
I think that's mostly the spirited driving. Twist isn't the most aerodynamic.
Mine with an upgraded batter does 110 Km regardless if it is summer or winter, I have it tuned using a Powerbox in full “sport mode” and definitely I do not drive it economically/conservatively
@@dmorenojwhich battery?
Good job!
been looking at the cells you replaced the old batterypack with , was about 1200euro excluding the shipping from china , taxen and fees , a 2012 twizzy can be found for about 3000 euro with a batterypack or 2000 without (you need the batterypack for the electronics inside it ) could probably get a little better price if you wait on a good deal and jump on it fast
all in all i think you would have a good running electric car for about 4500 to 5000 euro wish to me seems to be a good investment considering wat they ask for a original batterypack to own or rent
guess it does charge the pack from the original charger
I bought a 2020 Twizy last August (so 4 years old) for a little over € 5000, so I had a good Twizy with a good battery (100% SOH) without having to do a lot of work. That's also an option, if you can find a good deal.
@SolarWebsite yeah problem over here in the netherlands is that the batteries in the originally dutch licenced twizzy are.all leased from.renault , the ones with bought batteries are only available in germany and you need to reregister the car to get dutch papers , you pay import taxes and some.taxes.over the blue book value of the car (any car inported from within europe up to a certain age)
@@watahyahknow I also live in the Netherlands 😁 And yes, when I bought my Twizy (from a Renault/Dacia dealer who had used it as a loan vehicle) it had a rental battery. After some difficult and frankly nasty negotiations with Mobilize, the financial arm of Renault that rents out the batteries, I bought it.
@@SolarWebsite its wat innitially stopped me from buying an electric car , the cheaper versions all have rented bateries and the savings you make with the road tax excemption you make up paying the rental fees , and when you do break the pack its verry hard to get them to get you a replacement , usually they take the battery pack as they own that and let you keep the twizzy as thats yours , and basicly you end up with a verry large paperweight
nice to see that the battery replacement works , now i like to see someone recreate all the auzillery stuff like the charger and bms systems to communicate with the rest of a stock twizzy so you dont need an old battery pack to get an old twizzy without a batterypack working again
@@watahyahknow Yeah. I fully agree, the battery rental system sucks in many ways. That's why before buying the Twizy, I made damn sure I could buy the battery on day 1, which is exactly what I did.
I'll save you the details, but the process of buying the battery wasn't pretty, this Mobilize company (same company behind the Duo/Bento) lied to me about the VAT and were nasty about it too. So, I'll look at the Duo, but will probably not buy one because if I can avoid it I don't want to do business with Mobilize ever again.
Looks like you can get the 90 kms you were hopeful of.
Prachtige serie mannen, respect. Niet dat ik een Twizy heb of plannen daartoe, maar jullie enthousiasme is bewonderenswaardig.
PS klapperen die kunststof inzetraampjes altijd zo?
Thanks! Nee, in de zomer klapperen ze niet.
@ 🤣🤣🤣
Could you share your monitoring app and hardware??
What year twizy do you have? Mine doesn’t give you those extra 6km after turning the ignition off and on.
As a comparison my twizy with a powerbox achieves 70km in the summer here in Italy, travelling at maximum 50-55km/h. It’s a 2012 twizy with 42.000km and 74% battery health according to the powerbox. To achieve the 70km range really do drive in a conservative manner. Otherwise my range is about 50km. Currently at a temperature of 10-15 degrees I would expect to get 40-50km range if driving in economy.
I’m also looking in to doing a cell swap as I purchased an entire renault zoe 2021 52kw/h battery pack. It uses a 2P 8S module configuration, comprising of a total of 12modules. I have used them for my home solar victron setup, and left 4 modules for the twizy experiment.
I’m prepared to have to reconfigure the individual pouches that comprise the modules as to achieve the twizy’s 14S configuration and using all of the available space in the battery compartment. For this I might have to buy a Cold welder to weld the contact tabs.
I must say I do a lot of drifting with the twizy so my battery is quite depleted as it gets abused when in max power mode leading to a high current going through the cells.
What motor temperatures do you see when driving in a .... spirited... manner? I have a standard 2020 Twizy, not tuned in any way, and when driving maximum speed for some time the motor temps can get quite high. I don't know yet if that's normal?
how much did it cost you to make this upgrade and what cost it when u do it for me?
did you ave recharge this new batterie pack with the twizy charger ? and how many time it will take ? you make a very good work on that batterie updade !! congratulation
Mooi werk! Kun je ons ook helpen met het upgraden van onze Twizy?
Hi, very good job, thank you very much. Looking at your beautiful work gave me an idea for my Twizy. Rather than replacing the 14 cells of the Twizy and using the control wires of the original BMS, it would probably be more efficient to place these wires across 14 resistors connected in series as a voltage divider between the 2 terminals of a 16 or 17-cell 3.2v LFP battery equipped with its own BMS. In this way, the Twizy's BMS continues to read the correct voltages, while the battery's BMS with active balancer manages the new battery. What are the dimensions of the useful internal volume of the battery envelope? This is to find, for example, prismatic LFP cells and why not double the Twizy's capacity.
👍👍👍👍
Get rid of the annoying & unnecessary background music.
Say 'please'?
Ik zie dat jullie OVMS gebruiken op de Twizy. Wat is jullie ervaring met dit systeem? Ik zelf bezit een kleine Smart fortwo EQ en Mercedes Benz beeindigt in december dit jaar de Smart app ondersteuning omdat er gebruik wordt gemaakt van het 3G netwerk en dat bestaat straks in 2025 niet meer. Vandaar mijn overweging dit systeem aan te schaffen.
OVMS is een prima tool, wel echt voor de techneuten. De app is alleen niet zo mooi.
Check wel de documentatie of je auto goede ondersteuning heeft.
Ik heb overigens geen 4G module.
Is Twizy can more than 50 km/h? I was in Italy and rent Twizy. But it was unable ran more than 50 km/h.
you have 2 models one is limited to 50 a there is a version that is 80, more power and more speed. it depends on local regulations
Was oryginal battery also lifepo4? If not you will overcharge your cells, because lifepo4 operates on lower voltages than traditional cells. Can even start a fire.
As I understand it, LiFePO4 batteries are very hard to set on fire, even when mistreated. But still, for good longevity, a matching charger is a must.
I think (but am not 100% sure) the original Twizy battery has NMC cells.
Hi, The Twizy has NMC cells. The replacement cells are NOT LiFePO4 but NMC.
@@DIYDiscoveryDuo ah okay, i though those big blue cells are made only in lifepo4 version.
What is the reason you get such a low range. Some much heavier EV makes 12 kWh/100km.
Btw. Re-upload without this very annoying foreground music.
Music is too high volume. I can't understand what you are saying. Please remove the background music!
Guys, your content is amazing, but for one thing...the horrendous music, seriously it ruins your videos. It makes the videos hard to watch..
Great work, but I can't watch any more because of this horrible music. 😢😢😢
Thanks for the feedback, we do it better next time.
the orginal battery, are they to lifepo4?
on other comments I read, that the replacements were not lifepo4 despite looking so.
I wouldn't feel comfortable charging any ev in my garage especially if its anywhere near the house. I park my skoda at the end of the drive away from the house. And skoda have one of the best safety records.
It's rsky to charge any lipo battery's in the house
I think the risk is still very low. Look up the numbers (actual numbers, not click-baity "news" articles) on how many cars catch fire and how that's divided between EV's/fossil-fuelled cars.
The Twizy (with original battery) does have NMC cells, which do need to be charged carefully, but they're charged at a low rate (2 kW which equates to 1/3 C) so there's not much energy going into them anyway. In my Twizy, I have a Twiz'O'Meter connected to the OBD2 port, which allows me to lower the charging power all the way down to 0,7 kW, which should lower the already small risk even more.
But hey, nothing wrong with being careful.
@SolarWebsite compared with petrol cars it's actually rather high, in the uk the cases have been played down, Luton Airport car park being distroyed was a hybrid even though the media tried to say it was a diesel range rover. Batteries produce very distinctive fire. One thatcisnt easily put out.
Also several houses have court fire due to ev's. Not click bate
To be fair if you look on the London fire service website the vast majority of house fires are coursed by people charging Chinese scooters. Around 70% ..
Fly rc helicopters and racing rc cars, the risks posed by lipo battery's is something that is always present. Its not so easy to put an ev battery pack is a fire safety bag lol
