3S/4S/5S Bms 12V 16.8V 21V 3.7V 100A Li-Ion Lmo Ternary Lithium Battery Protection Board Li-Polymer Balance Charging

I ordered two boards. One came correct, the second with a burst case of a transistor (factory marriage). On call and work it was correct (I did not try to charge completely yet, but the indication works properly =)) Before opening dispute decided to contact seller. He answered quickly and politely agreed to refund the money completely for the fee. As the fee proved to be working, agreed on 50%. The dispute seems to have been approved, but the money has not yet received. Otherwise, everything still works. Banks I have Bu from the laptop battery, so I do not have illusions about the perfect balancing. Is there protection, Shurik twists, what else is needed for happiness? There will be jambs -- I'll add a tip.

Purchased for 4S Li-ion battery block. It almost took $ days. Easy to use, work as expect, but the soldering pads are a bit small for a high current discharge. Conclusion: good product for a price. ;) maybe the best budget BMS on market. Write no gimmicks. Moderately low to high performance also fit and not just for clothing bags for the sake of some soldering pads small think. Ali Sky otherwise seemed fit performance of cheap micro bms. recommend.

Thank you for receiving the item. Delivery, 12 days. Package bag, inside bubble film. The item has no damage. The quality of manufacture is good. The size corresponds to. I will check in the work, supplement the feedback.

Delivered to Samara for more than two weeks, and the main time spent on the eastern new year, the seller first rested, and then unraveled a bunch of arrived orders. I will try to unsubscribe after installing the board in the battery screwdriver and check performance. Then I will give or will not give recommendations

Good time of day. Thank you very much. I order from you a second time BMS 3s 100a boards. From the previous application applied for a lithium ion battery on a scooter, everything works. I recommend the seller and the store. Keep going like this. Good luck and prosperity. Thanks again!!!

Board BMS. Received in Brazil with 20 days. Still not auditioned charge and discharge to give my opinion. Just thought too small to make the welding wire monitoring and charge and discharge. But the board is very tough and rigid.

Received a week and a half, as part of the national team parcels. Good-looking. Ordered 4S, all resistors are in place. With such BMS and work recently. Packed in antistatic, traces of flux is not visible, soldered exactly.

The parcel came all the way! In Ufa in almost 14 days. Check in the work is not yet possible. I put in absentia 5 to the seller I hope the fee is working!

Came fast together with another orders. Looks same as on the pictures. Hope will works perfectly! More information after test results. Thank you

100a old BMS is first used to living in a little bear the four. Manual for Chan Chan read while watching when installed and will four key.

Works perfectly, charges, balances. I recommend, a very flexible board, by adding a zero resistor, you can at least get 1s a fee.

I got it in a month, I came looking whole, it looks good, only I can not check while the batteries are still on the way.

Delivery to Soligorsk 22 days, I take not the first time, there were no problems, I recommend the goods and the seller.

A good working fee, the elements are a little screaming, but it does not affect the work, it was delivered quickly

Shipping fast. It's like the description. I order not the first time. They work fine. Thank you seller!

Excellent module, reliably balances banks, suitable for power tool conversion from nickel to lithium

Goods arrived in good working condition. Package 5S 100A for cordless screwdriver ideal. Recommend

In the drill Sent 7.03.22 received 19.03.22G. Visually everything is whole, until I put it.

I have not checked the goods yet. Delivery as if not long and as if not fast.

Good product. fast shipping. But the package was opened before reaching me

Came in 21 days, all the reception, to the robot until he translated.

It's been a long time, but it's got it. Looks good, I'll add to it.

Shipping fast. Corresponds to the description. I recommend to buy)

the one and only bms for power drill battery conversion Ni->Li

Take the first time in this store, so can't say anything

Not checked, if there are problems, then unsubscribe ..

Fee BMS received, taking 5 cans, see how it will work.

The board had no damage, is not checked.

Norms. Works. The third time I buy

All norms. I'll try on shurika.
