FAQ
1. Which current of the PCB should i choose?
Take 13S 48V pack as an example: Which PCB you should choose depends on the power of
your motor or the current limitation of your controller. Below 350W ,you can choose 16A.
Below 500W, you can choose 18A, Below 800W, you can choose 35A,Below 1KW, you can
choose 60A. Above 1200W, the same. If you are not sure, please contact us freely.
2. Can i use bigger size of PCB than it should?
Suppose you need 60A PCB but you chose 80A, that is OK.
80A allows higher current.Nothing bad but a bit higher price.
But if you choose 50A, sorry it is too small. So you can choose higher spec but can't choose
lower one than it should have been.
3. What kind of charger should i choose?
Lithium battery must be charged by lithium battery charger. You can't charge it with a lead
acid battery charger. The lead acid battery charger might damage MOS pipe of the PCB.
4. if i have PCB, do i need any balancers?
Yes if you can add QNBBM balancers, that would be perfect.
The Main function of PCB is to prevent batteries from over charged or over discharged,over heated etc.
All the PCB /BMS in the world balance performance is not satisfactory.
With balancers added, the batteries lifespan will be longer and the capacity will be fully used.
5, How to judge if my PCB is broken or not ?
If you'd like to judge if the PCB is fine or not, please use a multi-meter and see if the voltage
of each cell is close to each other or not.when the volt difference is 1V, the battery will have
such performance:driving distance is short, cut off when started, charging time is very short.
under such situation , some battery is defective. When the PCB is broken, the battery can't be
discharged when you measured the battery volt is normal.

Multiple applications
Our smart BMS is used in many scenarios, such as electric scooter, e-bike, tourist sightseeing vehicle, electric tricycle, low speed EV, emergency UPS, solar street light, RV & home energy storage. 
BMS advantage: 1. We can design it for various lithium batteries like LiFepo4, LiMn2O4, and Li-polymer etc.
2. The main functions are: over charge protection, over discharge protection, over
current protection, short-circuit protection, temperature protection etc.
3. According to the customer request we can develop PCM in different sizes and structures.
4. BMS manufactured by high quality Mos and IC imported . Keep your battery long cycle service life time.

Packing & Delivery
Strong Packing
Our bms uses customized foam, there are grids in the middle of the foam, and each grid can place a bms to make the bms more stable. At the same time, we use waterproof tape to seal 3-layer UN carton, even in a humid environment, to ensure that bms will not enter water, and to ensure the performance of the bms.
