Always use a charger that matches your battery’s voltage and chemistry.
This is the most important rule.

For BOOANT batteries, common charger voltages include:
24V LiFePO4 → 29.2V charger
36V lithium → 42V charger
48V lithium → 54.6V charger
52V lithium → 58.8V charger
60V lithium → 67.2V charger
72V lithium → 84V charger

Using the correct charger helps ensure:
Safe charging
Full capacity
Better battery lifespan
Proper BMS operation

If you’re unsure which charger your battery needs, stop and check before charging.
Using the wrong charger can cause serious problems.

Why does my charger turn green too fast?

This is one of the most common questions we get.
A charger turning green usually means charging current has dropped very low or stopped.

That can happen for several reasons:
Battery is already nearly full
Charger isn’t connected properly
Battery BMS is in protection mode
Charger is faulty
Charging port connection is loose

A green light does not always mean the battery is fully charged.
If your charger turns green within seconds or minutes, something may need checking.

Start with the simple stuff first:
Check connectors
Check output voltage
Check battery voltage with a multimeter

My battery won’t charge,what should I check first?

Don’t panic,most charging issues are easier to diagnose than people think.
Check these first:

Is the charger output correct?
Use a multimeter to measure charger voltage.

Are all connectors fully inserted?
Loose plugs are very common.

Is the battery voltage extremely low?
A deeply discharged battery may trigger BMS protection.

Is the charging port damaged?
Bent pins or loose connectors can prevent charging.

In many cases, the battery itself is fine.
The issue is often the charger or connection.

Can I charge the battery while it’s installed in my bike or device?

Yes, in most cases, absolutely.
Most lithium batteries can be charged while installed.
That’s completely normal for:
eBikes
Scooters
Electric motorcycles
Energy storage systems

Just make sure:
The charger is correct
Charging port is secure
Charging area is dry
There is good ventilation
Avoid charging in extremely hot environments.

Can I leave my battery charging overnight?

Usually yes,if you’re using a proper smart charger.
BOOANT chargers use automatic CC/CV charging with auto shutoff.
That means charging current gradually drops as the battery fills, and charging stops when full.
That said, as a general safety habit, we recommend avoiding unnecessary overnight charging whenever possible.

Especially for high-voltage packs like:
60V batteries and 72V batteries
Good charging habits reduce long-term stress on the battery.

What happens if I use the wrong voltage charger?

Best case: the battery simply won’t charge.
Worst case: you may damage the battery, BMS, or charger.

Examples:
Charger voltage too low
Battery may never reach full charge.
Charger voltage too high
This is much more dangerous.

Overvoltage can cause:
BMS shutdown
Component damage
Excess heat
Permanent battery damage

Never guess charger voltage.Always confirm first.

Can I use a higher-amp charger to charge faster?

Sometimes, yes,but bigger isn’t always better.
Higher-amp chargers reduce charging time by delivering more current.

Example:
5A charger = slower charging
10A charger = faster charging

But charging too aggressively can increase:
Heat
Cell stress
Long-term wear

Fast charging is convenient, but slower charging is usually gentler on the battery.
For daily use, many riders prefer balanced charging speed rather than maximum speed.

Why is my 48V battery charger output actually 54.6V?

Because “48V battery” is nominal voltage, not full-charge voltage.
This confuses a lot of buyers.
A typical 48V lithium battery is a 13S battery pack.
That means:
Nominal voltage ≈ 48V
Full charge voltage = 54.6V
So seeing 54.6V on your charger is completely normal.
The same logic applies to other voltages:
36V battery → 42V charger
52V battery → 58.8V charger
60V battery → 67.2V charger
72V battery → 84V charger
Nothing is wrong.That’s just how lithium battery voltage works.

How should I store my battery if I won’t use it for months?

For long-term storage, don’t store the battery fully charged or fully empty.
The ideal storage level is usually around:
40–80% charge

Store the battery in a place that is:
Cool
Dry
Clean
Away from direct sunlight

For long storage:
Check voltage every 2–3 months
Recharge if voltage gets too low
Proper storage helps prevent deep discharge and extends battery life.

Can I use any charger for my lithium battery?

No.not all lithium chargers are interchangeable.
Even if connectors look identical, charger specifications may be completely different.
Before using any charger, always confirm:
Battery voltage
Battery chemistry
Charger output voltage
Connector polarity

A charger that “fits” physically may still be electrically wrong.Always verify before plugging in.
