PROS
High capacity
Build quality

CONS
Special 4.35V charger is required
|
Although they can be charged by ordinary Li-Ion charger (in this case capacity is around 2650-2700 mah) full capacity
reached when charged up to 4.35V. It measured as follows (cut off 2,9V):
1st - 2895 mAH
2nd - 2901 mAH
3rd - 2914 mAH

PROS
High (proven) capacity

CONS
Needs special 4,3V charger
|
Capacity measured as follows (charged up to 4.21V, 2A discharge current):
3.0V cut off - 2450 mAh
2,9V cut off - 2550 mAh
2,75V cut off - 2630 mAh
Seems capacity to be close to 2800 mAh when charged up to 4,3V as per datasheet.

Supports 0,9-0,95 A charging current when powered form PC USB.
Strictly follows CC/CV algorithm, terminates charge at ~0,1A.
Amazing module for such tiny price.

None

I've tested 4 pcs (discharge to 3V, full charge 0.4C, discharge 0.4C to 2.9V) and all
of them shown capacity exceeding nominal: 2602, 2605, 2587, 2598.
The only question is how many cycles they'll work.

None significant

Pleasant "pure white" tint, subjectively around 5500K.
Wide spot. There is sligtly greenish area around spot but
visible in short range on white surface only.
90 lm seems to be true but visually look around 70. .
