Why
you need a Battery Balancing System
The individual cells
in a battery pack are rarely an exact duplicate of all the cells in the battery
pack.
In actual practice,
when a pack of batteries reaches a specified charge cutoff voltage then the
charger will shut off. If one cell in a pack reaches that voltage before other
cells reach a full charge it will cause the charger to shut off – prematurely
denying the balance of the pack a full charge.
Conversely when the
weakest cell in a pack reaches its discharge cutoff voltage it will show as the
discharge point and shut down the pack prematurely – thereby denying the user
the balance of energy the other cells have stored.
These battery
equalizers prevent this from happening. This yields up to 30% more power and
will extend the life of the battery pack.
Benefits:
§ Quick and easy
installation
§ Keeps your batteries
voltage difference within 10mV!
§ May increase the
lifespan of your battery pack by 2-3 times by preventing the batteries from
being overcharged or over discharged
Features:
§
High
frequency pulse, dynamic battery voltage-amperage balancer
§
Simple
wiring and high efficiency
§
Works
with all charger amperage and voltage inputs
§
All
1S Single Balancers come with the interconnecting and battery wiring
§
0.5m/1.5ft
maximum suggested wire length for all the multiple series balancers. (35m 4S,
5S, 6S, 8S)
§

Modules
may work with 3, 4, 5, 6, or 8 batteries in series (AKA 3S, 4S, 5S, 6S, or 8S)
·
Does
not come with the wiring to connect to the batteries
Example:
A
144v pack of 48 cells,
20
in the front and 28 in the back
can
use 8S+8S+4S in front
and 8S+8S+8S+4S in the back.

Battery Fundamentals Primer
Note: This
balancer emits a very high-frequency tone that some people can hear if they are
within 10 feet.
Note: Please
check wiring diagram for how to connect these modules or contact us to avoid
making mistakes during installation.
Here are
several ways to make sure they are installed correctly:
1. Measure the
voltage of the batteries with a multi-meter to see if all the batteries voltage
is normal.
2. Listen. If the
balancers are connected correctly, they will produce a high-frequency sound.
Because the sound is quiet, you need to get close to the balancers. The more
balanced the batteries are, the smaller the balance current it will have, and
the softer sound they will make and vice versa. If they are connected the wrong
way, you won’t be able to hear the sound.

Why should I use the balancer?
1. Keeps your batteries voltage difference within 10mV!
2. Keeps your batteries safe all the time. No overcharging or over discharging.
3. Prolongs your battery lifespan 2~3 times
4. Very simple installation
5. Low price. You pay a small amount of money to protect your battery. Compare to the cost of replacing your expensive lithium battery, the balancer is very cheap.
6. Fast delivery. 1~2 business days after payment arrival.
How does the balancer work? How does it protect batteries?
This diagram tells you how the balancer works.
Each battery is compared to a cup.
Each balancer is like a pump. With the pumps, all the cups will have the same level of water.
The balancers are connected in parallel to the batteries.
They won't affect the charging or discharging of batteries.
