Hi all. I have new Coslight Harbin 48V 100Ah batteries. I haven’t connected them yet but I wanted to see if they can switch on. Tried everything but nothing seems to work. Does anyone have experience with these? They are bnew. I’m a noob. 

insert a paperclip or small screwdriver into the hole that displays I/0. That looks like the on / off switch.

I have done so but then its not responding at all. Thanks for your response.

hello,what eventually happened with the batteries

For safety reasons, especially during shipping Coslight employs a different battery switching on mechanism

1) First open the top cover of the battery, you will see the screws around the top cover

2) press the 1/0 hole with a paper clip, or anything that can fit in than hole

3) partially open the cover, take a screw driver and short the neutral terminal? with the positive (I think) (there is a black rubber clip which you have to remove in order to do that. Thats how mine were switched on by the technicians. The batteries will switch on.

I used the method described by Alyusuph

So you managed to start the battery? You will love them, excellent product

And when you connect them make sure the dip switches are correctly set. Btw

Yes I did. I am now looking for more of these. Would you recommend a supplier?

Where are you based? I got mine (Indian made) from AfroCube in Harare, they may direct you to a supplier in South Africa. Let me know if you need their vontacts. By the way, once switched on for the first time, you do not need to open the cover again, you can just use the 1/0 pin hole to switch on and off (a good way to tell you your battery was brand new).

Also when connected Slave and Primary) you just need to switch on one of them.

That’s useful regarding the slave and primary, Alyusuph, thanks, as I noticed they were always “live”. I got mine online and 2nd hand with no paperwork. Can I reset the BMS and is there a default password I can then use for each battery to log into the “Coslink” WiFi?

Unfortunately paperwork is the biggest problem. Great batteries without much documentation. I have tried to write to them in India but do far no response
