13 best batteries with pcbs
Batteries with PCBs (Protection Circuit Boards) are specialized battery packs designed to provide an extra layer of safety and protection for various electronic devices, including power tools.Here's what you need to know about batteries with PCBs:
Protection Circuit Board (PCB): A PCB is a small electronic component integrated into the battery pack. Its primary function is to monitor and protect the battery from various potentially harmful situations, such as overcharging, over-discharging, and short-circuiting.
Overcharge Protection: The PCB prevents overcharging of the battery by monitoring the voltage and current during the charging process. When the battery reaches its maximum safe voltage, the PCB interrupts the charging process to prevent damage or overheating.
Over-Discharge Protection: On the discharge side, the PCB ensures that the battery is not drained beyond a certain voltage threshold. Over-discharging can damage the battery and reduce its overall lifespan. The PCB disconnects the battery when it reaches the minimum safe voltage.
Short-Circuit Protection: In the event of a short circuit, which can lead to dangerous situations and damage the battery, the PCB disconnects the battery pack from the device, preventing further discharge.
Temperature Monitoring: Some PCBs include temperature sensors to monitor the battery's temperature. If the temperature rises to a potentially dangerous level, the PCB can disconnect the battery to prevent thermal runaway.
Cell Balancing: In multi-cell battery packs, the PCB may also perform cell balancing. This ensures that each cell in the pack is charged and discharged evenly, extending the overall life of the battery.
Compatibility: Batteries with PCBs are designed to be compatible with specific electronic devices or power tools. It's crucial to ensure that the battery pack with the PCB is the correct fit for your device to avoid compatibility issues.
Safety: Batteries with PCBs provide an extra layer of safety, reducing the risk of fire, overheating, and damage to the device or tool. This is especially important for high-capacity batteries used in power tools.
Charging: When charging a battery with a PCB, it's essential to use a compatible charger that matches the voltage and current requirements of the battery. Using the wrong charger can bypass the protection features of the PCB.
Replacement Parts: If you need to replace a battery pack for your power tool or electronic device, consider purchasing one with a PCB. This will help ensure the safe and reliable operation of your equipment.
In summary, batteries with PCBs provide an added layer of protection against overcharging, over-discharging, short-circuiting, and other potentially hazardous situations. They are commonly used in power tools and electronic devices to enhance safety and prolong battery life. When replacing battery packs, always ensure compatibility and follow proper charging practices to maintain the effectiveness of the PCB's protective features.

User questions & answers
| Question: | Is the max power handling 25 amps at 12v or 3.7? (300w or 92.5w |
| Answer: | At 12v. I've had no problems pulling 15-20 amps out at 12v. |
| Question: | If a single cell drops below 2.3V will the entire battery pack be disconnected? It appears that all three cells need to drop below 2.3V |
| Answer: | Calling this tiny board "BMS" is overkill, This is more of a simple "Battery Protection board" with little bit of so called "BMS" thingy. This BMS won't cut on discharge until at least one "cell-group" has dropped to a dangerously low voltage.. Since you see the arrangement is 3S and with 5 x 18650 in parallel, one of such cell-group developing an internal fault and dropping to a dangerous low level of 2.3 while the rest of the cells in the 3S configuration having more than 4.0 is very rare and if that ever happens, it better that the BMS disconnects that cell-group to save the other two groups. To answer your question: - Yes! if single cell drops below 2.3v it does have a potential for the entire battery pack to be disconnected from the output terminal by design. |
| Question: | When using a 12v power supply to charge the battery, will the BMS automatically shut off, or can it be overcharged |
| Answer: | For this item the max voltage that should be put into it for standard max voltage 4.2v 18650 batteries is 12.6v (4.2v x 3s). Any more than that and you risk overcharging (damaging) your batteries. For the longest life for the batteries over time 12v should be most optimal (ends up being about 8-10% under max capacity of most batteries). |
| Question: | One you build the battery, i assume you need a 12v dc charger. anyone have any reccomendations for chargers |
| Answer: | find something at 12.6v - there is a company called talentcell on amazon that sells some already put together batteries using 3s 18650 cells at various parallel configs to give different capacity. They do sell their 12.6v chargers separately - but keep in mind they are designed for 3s2p or 3s3p levels of setup - i think 1 or 2 amp - so depending on how big your build is - these may not work for you. I have in the past gone with 12.6 volts and used 1 amp for every parallel set of cells. so for a 3s5p battery i had a 12.6v 5a charger - lots of those on here too. |
