Would have made sense to double up on the heaing pads instead of usig a voltage converter/regulator. Then wire heating pads in series in pairs. This would have advantage of spreading the heat more around the pack 😊
This is exactly what I was looking for, thank you for sharing! Is ventilation/cooling a consideration if things get too toasty? 24v heating pads are more common now, and I am considering adding a thin layer of closed-cell insulation to the inner floor and walls. Would you still stick with 3 x 30-watt pads? To the 'never work' comments, we're not trying to roast a chicken, just keep things above freezing.
Think I would of just used the heating function provided by the BMS through a fuse to the series wired heater pads you can just use the app to set the on off temperature. Putting all that electronics in is just more to go wrong. I appreciate what you said about the connecter blocks use waggo ones they are demountable but a lot better quality
Believe the jk bms will only switch on heating if its trying to charge. So the battery temp could fall way below freezing. Your then waiting for relatively small wattage to raise the temperature of a family large thermal mass.
😄 Yes, you can. Do it! 🔥 I guess you are a rookie, like this old man you watched at.. He built a heated box for the cells, but let it open (with holes on the top). So smart.. so efficient... Not to mention that wobbling "heat sink" scratching the plastic cover of the cells when vibration starts.. I gues he charged that (much) rookie customer more bucks for this "special" option 😄 I wonder where he find them..?! But, wait... You might be one of them..? 🤔
@@silviuflorescu6838 I know you can do it (I'm an electronics engineer by trade), my comment was more of a question as to why he didn't use that option. In his defence he did say the customer was making an insulated box for it, and yes I did spot the potential for the aluminium heatsink to move and damage the cell insulation and potentially short two cells .
There is no way that little heating pad hanging loosely inside a wooden box would radiate enough heat to sufficiently warm the battery on a cold winter day. This is completely untested and would never work. That's going to be one unhappy customer...
It was made clear that the box was going to be in an insulated enclosure. By using a temp controller it only needs to maintain temperature as the ambient temperature drops. 30 tob50bwattsis more than enough. 😊

This is great gentlemen thank you for the open source information!! Best!!
For 24v just put 2 12v pads in series 😊

Does the JK BMS allow switching on/off heating elements? I thought it only switched on/off the battery inputs to prevent charing below a set temp.

Could you not use two heating pads wired in series to make a 24v version?
😄 Yes, you can. Do it! 🔥

Link to the heat controller?

He’s been pretty happy so far. 🙂
You're right. Those do next to nothing
