I agree with using thicker foam around cells, I found using the Cheap 10mm Thick Camping style mattress (usually blue in colour) works great for large battery builds. Obviously your battery box needs to be large enough to allow for the extra thick foam I recommend. (20mm extra across the entire battery box) A Very nice build so far, Great Work 👍 👌 👏
Yeah, me too. The plan is to have the whole project finished, with a running ATV, by the end of July. I’m at the final year of my master studies. Hopefully there will be enough hours to to in the project 😊
looks great haha that thing with the angle grinder happened to me the other day when I was working with the skis but I drop the angle grinder so it went into the leg luck it was a grinding wheel on and not a cutting disc
Yes, I can’t wait for that myself. I’m travelling to Norway 🇳🇴 for 13 months this summer, so the plan is that the ATV needs to be running by end August so I can bring it to some real mountains and not just the flat fields of Denmark. I’m currently finishing my master thesis, so this is why things are not progressing so quickly at the moment, however I plan to accelerate more through the process. 😊
@@goelectric8269 Yes I have heard that it is difficult to find sufficiently effective BMSs.

Thanks. It is still up for consideration. But it will be a slide in and out solution, so that the battery can also be used to power other things than the ATV. I’m thinking that just a couple of bolts will clamp the battery box to the frame and the sliding rails 😊
Yep, I agree. The only slight thing there is with these LiFePO4 batteries, is that they have a longer lifetime if they are under compression in the battery pack. As they are charged and discharged they grow and shrink slightly, causing the electrodes and electrolyte to get disordered. Therefore in my case there will not be an air gap between them, but maybe I’ll make a cooling grill in the top of the battery box, if it becomes an issue. I plan to have a temperature gauge with the BMS, so I can monitor them 😊 However the avg. temperature in DK is around 8-9 deg C, so I plenty cold outside as well.
Good question. -I have calculated with a consumption of 0.15 kWh/km, which was determined by converting actual gas power 4x4 ATV consumption measurements to energy consumption in joules and then to kWh. With my 9 kWh battery pack I will be able to go (9 [kWh]/0.15 [kWh/km]) = 60 [km] in unfavorable conditions and rough terrain (cold and muddy). Leisurely driving would probably give me around 100 km range :)
ITSMART Yes, U definately should. It’s a fun and educating/interesting process. The only thing that surprised me bit with such an electric vehicle conversion is the cost of components, where motor, batteries and controller are the most expensive. - But Luckily there are some cheaper components out there if one is not into a to expensive project. Check out Goldenmotors webpage, they make nice products also at a fair price. Also if one can live with lesser range and more frequent charging, this is also a good alternative, to reduce excessive costs.
Love your videos but get some heavy duty gloves when you are using the grinder. I nearly lost a finger from a bounce like the one that happened to you. Stay safe :)
