Go to the original thread and read. Plenty of info
I have linked up an quick instruction at the batch 2 thread (first post). Please go take a look. Most important thing is to config your pack. Other than that just wire it up.
Be careful on polarity, and always use a current control charger to charge.
Have fun.

Quality looks good. A couple of solder joint are sketch. For example the pressed in screw stands have no solder so I might flood those if they donāt survive my testing. Itāll have to wait until tomorrow night though as Iāve been busy all weekend
Hi we asked the press joint supplier, these are meant to be non soldered. They call it cold welding.
Sam
Nice to have you on Board for quality check! I cant wait to hear your results.
The cold Welder joint Sounds like more top quality
Is there more left in second batch?
Should be a few left, but I think should be closed soon. Some users wanted to change to getting extra units.
(If thatās you, please let me know to update the count.)
Sam
Are you interested, not many left. Should be closing soon.
Iāll take 4 total
Iāll entertain the idea. You got pm
Them germans always ahead of the game
I still donāt know if I like them or not. Lol They are very bulky. Iāll need to make a new enclosure for this board.
The large terminals and balance connector. Theyre pretty massive. They end up making the board really tall.
I was thinking I could mount the BMS on top of my battery where the old one was but the height makes it too tall and uncomfortably low to the ground. I may get away with making a longer enclosure but if that doesnāt work Iāll have to get taller risers
Here are some pics.
Thanks for the pics and dimensions. I am used to the Supower 10s 60A BMS which is about 53mmx115mm. I am putting it at the end of the pack so should be fine but can see how it would be difficult on 12S or shorter boards. I hope you can get it to fit!
We should not forget that this bms is for high load up to 140a. Currently it only has a 80a fuse, i just ordered some 100a too, but it can do a massive load. So it cant be too small.
Weāll see how long it can hold 100A once I bypass the fuse. If you thought Sams resistor was big wait until you see mine lol.
10 kW Resistor arrayā¦
WTF is that for??? I wanna see!!!
