Batteries arrived intact, there are no declared 4000, 1-3800mah 2-3760mah 3-3680mah 4-3400mah. I wrote to the seller for this, he says that the batteries need to go through the 3rd cycle crash as always, I will replenish the feedback after the 3rd cycle, I don’t think something will change significantly, the delivery is 70 days long with one track number, the seller warned about it, I will try.

High quality production. Time will show the work. Delivery took more than two months. The seller warned and apologized.

The battery does not have 4000 ma, but the test results are not bad.
A***e (verified owner) –
Incredible how much capacity they store. Tested with liitokala m4s charger and it’s about 3800-3900 capacity which is pretty good. My 6 year old panasonic 3400s which used to be the best is around 3200s now.

I made myself an excellent battery, but they initially have a protection board that limits it to no more than 4-5 amps. It needs to be removed, then everything will work perfectly.

They will work in a flashlight. It has been 18 days, which is too long at this point; time will tell how long it can withstand the load. They arrived almost charged.

The average capacity tends to decrease by 1 % for the last half-year.

1. Delivery took more than a month
2. The batteries turned out to be larger in size, they don’t fit in the installation space, a waste of money.

A normal product, not of poor quality, and a good price-to-expectation ratio. Time will tell if it can be better.
I***v (verified owner) –
The batteries do not match the labeling.
U***о (verified owner) –
Received the order in 21 days. I ordered it for my wife because I already got one for myself. Large battery capacity, holds charge well. I recommend it.
AliExpress Shopper (verified owner) –
The size of the batteries is quite large if you remove the protection that is there. They don’t fit into the battery compartment. It’s disappointing.
o***v (verified owner) –
I received it, let’s see how it will work. Received it 8 days late while I was writing and making adjustments; they were fiddling around, and I still wouldn’t have received the package. They don’t want to provide a cashback; I have to submit a claim for the lost order to the cashback service. Very dissatisfied with the store’s performance.
