SHIMANO BATTERY BT-E8010, REPAIR - CELLS REPLACE PROCESS

[@davidsoares2676]

I had a very unpleasant experience. A client of mine, brought the functional battery and I in my tests I endeavored the battery! My tests consisted of checking the full capacity of the pack before balanced, which in the case measured 10.6Ah and how much capacity would have after the active balance. In the case measured 12.5Ah after the test. The stress range, from 2.5 to 4.2V by cell. Never do this with BMS on, to do this test I should have removed BMS like Mcellbatteris said! Anyway ... living and learning. Congratulations on your video, very good!

Doesn't it lock when you disconnect the BMS? Is the disconnection order first flex control series and then download or is it indifferent?

Hi. Is there a way to "unblock" a blocked BMS on Shimano Steps, or will replacing the dead cells with new ones reactivate the BMS? I'm interested in repairing the battery for a Shimano Steps BT-E6010. Thanks!

As you see in the video the bms is still working

You need security Torx heads to remove the screws. To release the two little covers for the screws, a good idea to lift up with a chisel from below. I cant see any way to remove these without some damage.

Hi, you can use scalpel or some blade. It can make some little damage but it doesn't matter.

Is it possible to buy the laser cut nickel sheets somewhere? Or are you planning to sell it?

[@mcells_batteries]

Yes, we will sell them. But for now, if you are interested please contact us on email : [e-mail]

The standard capacity fo this bt8010 is 504wh, is it possible to replace battery cell with higher capacity lets say to get 630wh? I have 2 of those bt8010 one is the new one just bought it, the old one its battery capacity already drop maybe just 50-60% in full charge. I plan to send to battery repair shop and upgrade capacity if possible. Thanks

[@mcells_batteries]

Hi, there is no chance to upgrade capacity. Cells has 3500mAh so final kapacity is 14Ah (504Wh).

hello, I knew that these bms block if you take off the cells! how to do it right ? Thanks

[@mcells_batteries]

Hi, we repaired several of these batteries and there wasn't any problem. BMS can be blocked when some of cells has lower voltage for longer time.

@@mcells_batteries Hi. Is there a way to "unblock" blocked MBS or will unhooking it and installing new batteries do this?
