Daly Smart BMS 14S 48V 150A 200A 250A Li-ion Common Port with Balance BT/RS485
14S 48V 150A-250A Li-ION BMS Specification: 485
communication : 485 communication is Universal Asynchronous
Receiver/Transmitter, It transforms the data to be transmitted between
serial communication and parallel communication. As a chip to convert
parallel input signals into serial output signals, 485 communication is
usually integrated into other communication interfaces.485 communication
cable can support connection bms between PC and you can set up the
parameter by PC screen. Bluetooth module : available connect with Android and IOS App and can review the battery status in real time by mobile phone. FAQ Q: Is this BMS suit for my battery?

Q: How do I know what material OR type my battery is ?
A:
Please look the battery body,if the normal voltage of your battery
shows 3.2V,the battery is LiFePo4.If the normal voltage of your battery
shows 3.6V or 3.7V, the battery is Li-ion or Li-polymer battery, You can
also ask battery manufacturer for the material of battery.
A: This BMS suit your battery or not depends on below 2 points:
How many series you cell is in your battery pack? The BMS you buy must be same series as your battery pack.
What
material your battery is? Only the LiFePo4 battery has different
electric parameter from other battery, so if you need buy the BMS for
LiFePo4, Please let us know firstly.
A: We take 13S 48V16A BMS as example:
Common
port 16A means your charge cathode and discharge cathode are connected
in the same point end (our P-), charge cathode and discharge cathode
are used in the common connection port, so the charge current and
discharge current are same as 16A.
Separate port is separately
connected by charge cathode (our C-) and discharge cathode (our P-), so
the charge current and discharge current are different, discharge
current is 16A, charge current is 8A.
A: The working principle and function are as followings:
When
your one cell voltage was reached balance voltage(Li-ion 4.18V, LifePo4
3.6V), that cell balance start work, balance resistance starts
discharge with 35mA, that cell was in both charging and discharging
status, and other cells were not reached balance voltage(Li-ion 4.18V,
Life Po43.6V), so they are only in charging status, when the fast cell
voltage was reached overcharge voltage (Li-ion 4.25V, Life Po4
3.75V),BMS starts off power protection, all the cells are stop charging,
this process will enable your battery charging in balance current, and
your battery voltage are in balance status.
However, if your cell
voltage difference are in a big range, The equilibrium effect is almost
zero,The solution is to replace cells with large voltage gaps.
A:There
is no direct relationship between battery capacity and BMS current, big
capacity doesn't mean big current, but rely on continue current, that
is to say if your engine is powerful, you should choose high current of
BMS, it is not relied on battery capacity.
Q: What type of charger should i choose?
A:
Lithium battery must choose specific charger, don't use charger for
leadacid battery, for leadacid charger may have MOS with high pressure
breakdown protection, which will not protect of BMS over charge. LiFePo4
battery charger voltage = number of battery strings X 3.6V, while
Li-ion battery charger voltage = number of battery strings X 4.2V.
Q: What current BMS should I choose ?
A: Take 10S 36V as example:
What
current BMS you choose is depend on your E-bicycle motor power and
current limitation of controller,eg.16A for 350W and below, 25A for 500W
and below, 35A for 800W and below, 60A for 1000W and below, over 1200W
are contact with our service specialist for suggestion, continue
current shall be higher than current limitation in controller.
A:
No, we don't have MOQ. different customer have different requirement
,we can provide various capacity and size as per your requirements, also
ODM / OEM is welcome.
A: PayPal, T/T, L/C,Western Union and so on, everything can be talk.
