Pack Dimensions?

Does anyone know the dimensions of this pack?

67.2v 50ah 3.36kWh Lifepo4 Battery 21s - $44/kWh

At $usd 44/kwh its a great deal, but not knowing the size is limiting for design... My only gripe for battery hookup really. All other things I've sought from them have been phenomenal deals/shipping/etc, just sometimes listings are absent of any effective dimensions.

Based on weight and visual proportions, I'm guessing about 13" square by 4.5" tall. Not a great format for a bike, but doable for good sized cargo bike and pretty good for a trike or 2-track vehicle.

They'll tell you dimensions if you email them about it.

The white connector appears to be the Molex connector used for ATX 24pin PSU connections in computers. If so, then this is the relevant section of the Molex drawing, with dimensions. You could use that to estimate the rest of the dimensions.

I bought two of these. I can get you numbers tomorrow if you still need them. I can get you the BMS connector part number I ordered off digikey as well. In the meantime I’m trying to source a charger.

Sure, the diem would help. I noticed Bh cleared out their current inventory, but there might be more coming in. Thanks.

The packs are about 5” high, 16 wide, and 14.5 deep. However, on the depth there are some external wires and mounting brackets. If you keep the brackets, plan just under 15.75. The wires are zip tied in place and can be moved if needed, but if you want to keep them there and pull the brackets give yourself about 15

Also yeah, they cleared out and then restocked and that’s when I got some. If you get a lead on a good charger let me know. As for the BMS connector I use digikey part number WM3811-ND. It’s 4.2mm spacing on the headers.
