complete batteries are widely available on aliexpress with 10s5p or 13s4p configuration and even 14s4p would if the cells assembled side by side without the plastic holder (for instance Luna Cylce offers this configuration), but i would like to purchase the case only and use cells for my specific needs together with a high-current smart BMS.

nice find, thanks^^ will contact the supplier.
 
One place they say minimum 10 another minimum 5. I'd take two on a group buy.
 
I'd guess because they ship by volume as well as weight they will be $45 distributed. Adding maybe $10 in shipping if there was a group buy distribution. I wrote Eric at Luna and suggested this item be stocked, but that will take weeks if not months to come to fruition. Hopefully he has already ordered some!!

I've searched nearly an hour every other day for the case. After a couple if weeks this is the best lead for a "Hailong-1".

I also suggested in several contact that the vendor would do well selling individual packs. I'm hitting up my battery supplier as well but noticed they no longer list this case. Grrrrrrr.
 
HA! They pulled their store for the holiday!
 
http://en.kssssj.cn/ is the manufacture, but please don't try contact them....

Sates side sellers are going all out packing this case with 29E/29PD and then trying to draw 40A out of it......

The things really designed for the 250W/350W eBike market.

Take a look at the discharge pin female mount

I guess if you parallel them in groups of two you would stand a better chance :oops:

Do I read that description correct...?
.... We like this battery because it has a cool cell holding block that bolts together holding the cells in the needed configuration. The cell holding block eliminates time consuming spot welding and makes swapping out a defective cell a breeze compared to the spot welded packs. -
So you can assemble a 13S, 4P, pack using loose 18650's, without any spot welding ! :shock:
 
NAH! Chinglish.

EVA will sell them one at a time after the 17th.

Sorry I thought you grabbed it from the site with the case.YES! I remember Biktrix posting a compression pack using that case.
 
I think...
 
Roshan at biktrix indicated there was a compression pack and showed this same kit with batteries. I tried unsuccessfully to get a case then.

Ordered!
 
Hi guys

I sell these cases (eMax eBikes Aus) and there is no special trick to get away from spot welding. The cell holding design is quite sturdy but you still need to weld together the cells in your desired combination.

The pack sits well on the bike but we always end up adding extra holes in the metal baseplate for a strong zip=tie or similar.

THe pack does have its shortcomings but probably the best frame-mount style currently available.
 
EMax, thanks for the input, but now you have really confused me !
...but I guess you are in the best position to comment as you use the cases.
Maybe there is more than one internal cell holder available ?
How much do you sell the case for ?
 
No there is only one design.
There is no way you would get the compression you need from the plastic shell. Also the cells are horizontally aligned and the case screws together vertically.

I don't have any spare cases without cells in them at the moment. I can order some if you are willing to wait. We can make custom spec batteries for this case but all involve spot welding.
 
I suspect there is some missing info here somewhere.
The EMPowerdcycles site clearly states there are two internal configurations for these packs, a 52 cell, "compression" only version using a special internal clamping cell holder rack, and a 56 cell spot well only version .
Personally , I suspect there are possibly other versions also for different voltages and cell counts ( I have seen 36 v, 40 cell versions offered.
Some of the images on line also show both welded pack assemblies and non welded packs , clearly showing the horozontal clamping arrangement....like this...
 
Mine came today. $53
I'm not impressed. The Dolphin is a superior case, questions and pictures to follow. I wish I'd have ordered a dolphin...guess I will do that next. Came 13s4p 52 cells. Have to decide, do i build or sell off and wait for dolphin. Dolphin us definitely more robust.
