Description of High Performance 14.8V 4S 30A 18650 Lithium Battery BMS PCB: Advanced Integrated Circuits Protection Board

Over charge detection voltage: 4.28+ 0.05 V,Over charging voltage: 4.08 ± 0.1,Over discharge voltage: 2.55±0.08,Working current: 30A. Balanced current: 60mA,Working current: 30A, Over current: 60A. Main function: Over charge protection, over discharge protection function, short circuit protection function, over current protection function, balance. Short circuit protection function: there is, disconnect the load can be self recovery. In order to achieve a better balance of the balance effect, please use a 17V power supply and a current capacity of 0.2 times (self-stop current is less than 30mA). Because the equalization current of the equalization IC is about 65mA, and most of the 16.8 lithium battery chargers on the market, the chaCannot be used for xenon lamp, hand drill battery pack, power tool type battery pack, vacuum cleaner, sweeper battery pack, electric bicycle battery pack, baby car battery pack, 550 or more power.

10 amp maximum

Works for both triggering and equalizing, but not for sinking amps. The first time I tried to draw over 10 amps it died and now won't let anything through.

Pros
  • Equalize current: 60mA, Operating current: 30A, Maximum current: 60A
Cons
  • Good, but not great

Why bad reviews?

This scale - checked with a witness counter, verifies that charging is completely off. Now let's test the low voltage shutdown. The main reason I bought off-road bike lights without DC charging.

Pros
  • Overcharge detection voltage: 4.28+0.05V Overcharge voltage: 4.08±0.1 Overdischarge voltage: 2.55±0.08 Operating current: 30A
Cons
  • There are other interesting options.

Product performance is best in power converters

This product appears to be a solid solution for lithium battery applications, but has hidden flaws. It does not work reliably with an inductive load like a motor. Also, an undocumented reset is required to allow the battery to charge. The distributor/manufacturer of the product is aware of both issues but cannot resolve either of them.

Pros
  • short-circuit protection function: yes, load disconnection can be self-recovery.
Cons
  • Mostly OK, but...

Faulty BMS: power converter

Avoid this BMS! The PCBA was used for a 4S 2P block with a maximum voltage of 16.8V. The PCBA only output about 2.78V when connected to a Li-Ion block. I then applied a charge to the block and the PCBA then came out of this state and put out 16.8V. After a few minutes, the board went back to sleep, outputting only 2.78V. The only way I found to get it out of a 2.78v state is supposed to be 16.8v. This does not allow me to use my package. I have contacted the seller but have not received a…

Pros
  • Main function: overcharge protection, overdischarge protection function, short circuit protection function, overcurrent protection function, balance.
Cons
  • Long delivery time

Terrible quality, the board in the photo didn't fit.

Wow where to start with this BMS. First of all it doesn't work. The fee sent is not the one shown in the ad. If you're looking for a quick synopsis, please read on (you've been warned lol). I've been using 4S BMS boards for quite some time because of their protection features for my portable bluetooth speakers. I design and fabricate my own charging board PCBs and rely solely on these BMS boards for output protection and undervoltage lockout. I have found over the years that the board for sale…

Pros
  • To achieve a better balance of the balancing effect, use a 17V power supply and 0.2 times the current (self-stop current less than 30mA). Because the leveling IC leveling current is about 65mA, most of the 16.8 lithium battery chargers on the market can not be used for xenon lamps, hand drill batteries, power tool batteries, vacuum cleaners, sweeper batteries, electric bicycles, children's car batteries, power 550 and more
Cons
  • Frequency
