1A Active Equalizer
Feature:
1.The newly designed DALY battery equalizer adopts the latest transformer inversion active energy
transfer technology to balance the voltage difference of large capacity battery pack, recover
battery capacity, refresh your battery pack and extend the battery usage life.

FAQ
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.
Q: Is this BMS suit for my 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.
Q: What is the Common port and Separate port? what is the difference?
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.
Q: What is the balance function?Do we need cell balance or not?
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.
Q: The relationship between battery capacity(AH or mAH) and BMS current(A)?
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.
