    30W Solar panel mount with MakerbeamXL (small T-slot aluminum extrusion beams)

    Hello all, I bought a small 30W solar panel that I plan on hooking up to a 38 Ah battery and Victron 250 VA inverter. I planned on using my dusty set of MakerbeamXL to mount it but it didn't seem to work at first because the mounting holes are too big for these tiny screws. Anyway after a bit...

    Drill holes in busbar / flexibar: equipment needed?

    In order to make holes through a Flexibar (to be used as busbars between battery cells), the manufacturer recommends using a hole puncher such as their MFPT. The problem is that their least expensive piece of equipment, the MFPT, costs € 1260.73 and that is a lot for something I will seldom...

    Source for EVE 280 custom busbars?

    Do you ship to Europe? I would very much like to buy 12 more busbars for my 304 Ah cells.

    Shorter (7cm) busbars: what are they for?

    Yes, I got them from Shenzhen Luyuan Technology Co., Ltd. Besides forgetting to respond to my messages when I initially asked about more busbars they've been lovely and very helpful. It will still be a little while before I have everything setup and tested; FreeCAD plans are slowly being...

    Shorter (7cm) busbars: what are they for?

    Got home and measured them, I think it's the eve datasheet / product specs that are wrong. I measured approximately 2.5 cm between the terminal and the smaller edge of the cell, which seems to match with the smaller busbars I received. The datasheet shows 9 cm between terminals which would mean...

    Shorter (7cm) busbars: what are they for?

    I guess so, that's all I can make sense of. Amy ended up getting back to me after I told her I received the batteries so I will ask her about it after I double check the size of the cells I got.

    Shorter (7cm) busbars: what are they for?

    Hello all, I just received my 304Ah EVE battery cells ordered on Alibaba and I am very confused about the busbars I got: A box contains two 9 cm long busbars which allow connecting two cells sandwiched together (since I calculated the cell terminals center would be about 7.35 cm apart...

    How to deal with uneven placement of compression springs?

    Neat! Show us your enclosure when it's done please :)

    How to deal with uneven placement of compression springs?

    I think that's what I will do, thank you :) Do you leave your battery exposed like that / not afraid of something falling on it / intruding and shorting it? My plan is to put acrylic on the sides that are not aluminum.

    How to deal with uneven placement of compression springs?

    What is this crossmember you are talking of? Thanks for the feedback :) I guess the distance between each rod would simply be cells_height / #rods, and I should avoid putting any springs on the bottom unless I put the same number and at the same distance as those on top?

    How to deal with uneven placement of compression springs?

    Compression springs do not offer an even 11 psi if they are not distributed evenly, as that is often the case (especially if there are none between battery packs which is often the case). Springs should thus be adjusted to each offer a separate force. I've posted about it on and I don't have...

    3P battery connection with provided 2-holes busbars: use a washer to fill in the gap or make custom busbars?

    Actually it works out perfectly if I use two of the busbars as terminals (I do need to get more busbars though, I got 24 of each in my order.) Still curious about the right ways to go if this issue pops up.

    3P battery connection with provided 2-holes busbars: use a washer to fill in the gap or make custom busbars?

    That's a great idea that didn't cross my mind :) Not sure I would be able to do it well though. Will see once I get them. Thanks! I will order some copper washers. It looks like M6 (I believe that's what the terminals are?) with 2 mm width are hard to find so they'll probably come from China...

    3P battery connection with provided 2-holes busbars: use a washer to fill in the gap or make custom busbars?

    I am in the process of modeling my 3P8S battery out of 304 Ah cells from Amy, and I just realized that using 3 parallel cells with the provided two holes busbars means that the busbar is not making contact with one of the terminals. Would it be appropriate to use 2 mm washers to fill in the...
