High-Capacity 36V Rechargeable Battery
The HL3633B stores
1044Wh of energy,
providing a high-capacity
power source for compatible
DC-powered equipment.
The battery uses
rechargeable lithium-ion
cells, offering high
energy density and
lower weight compared

lead-acid battery systems.
BiXPower HL3633B 36V high-power rechargeable battery.
The battery is designed
for applications requiring
substantial DC power
without the size and
weight of multiple
traditional lead-acid batteries.
36V Nominal Output – Actual Voltage Range 30V to 42V
The HL3633B is classified
as a 36V battery,
but its output voltage
changes as the battery
charges and discharges.
When fully charged,
the battery output
is approximately
42V DC.
During discharge,
the output voltage
gradually decreases
until reaching the
battery's lower
operating limit
of approximately
30V DC.
Typical 36V battery voltage
change during discharge.
Important Voltage Information:
The HL3633B does not provide
a constant regulated 36V output.
Only connect equipment designed
to accept the complete
30–42V DC
operating range.
High-Power DC Output
The HL3633B is designed
for high-current DC
power applications.
Its maximum continuous
discharge current is
40A.
The battery also supports
a maximum burst discharge
current of 60A
for up to 10 minutes,
subject to battery
condition and temperature.
Maximum usable power
depends on battery voltage,
current draw, wiring,
connectors, and the
connected equipment.

The values above are
voltage-times-current
calculations, not separate
guaranteed equipment ratings.
The original product guidance
recommends connected equipment
requiring 1200W or less.
Application Recommendation:
For direct-use applications,
choose equipment with a
power requirement of
1200W or less
and compatible with
the full 30–42V range.
Also consider motor startup
surges, wiring and connector
current ratings.
Battery Terminals and Connections
The HL3633B features
heavy-duty DC output
terminals and a separate,
specially designed
battery charging port.
The output terminals
provide direct access
to the battery's
30–42V DC output.
Always verify positive
and negative terminal
polarity before
connecting equipment.
Use appropriately rated
cables, connectors,
overcurrent protection,
and secure terminal
connections for the
intended application.
Important:
The battery output
terminals are for
discharging only.
Do not attempt to
charge the battery
through the output
terminals.
Always use the
designated charging port.
200W AC Battery Charger
The HL3633B uses a
specially designed
charging port.
The charger
regulates charging
voltage and current
for the battery.
The battery's internal
protection circuitry
is not a substitute
for a properly regulated
external charger.
Typical charging time:
Approximately 5–6 hours
with the compatible
200W AC charger,
depending on battery
condition and
charging circumstances.
Charger dimensions:
Approximately 8 x 5.5 x 3 inches.
Charger weight:
Approximately 2.5 lb.
Battery Connected to Optional AC Charger
Charger Sold Separately:
When ordering, select
the battery with
the optional AC charger
if you do not already
have a compatible
BiXPower charger.
Battery Package and Charger
The standard battery
purchase includes
the HL3633B rechargeable
battery.
Always confirm the
selected package
configuration before
placing your order.
Application 1 – Direct 36V DC Power
The HL3633B can directly
power compatible
36V DC equipment
that accepts the
battery's actual
30–42V output range.
Potential applications include:
- Compatible 36V DC motors
- Electric scooters with suitable electrical specifications
- Portable DC-powered equipment
- Compatible industrial devices
- 36V electronic power systems
- Custom DC power applications
Before connecting a device,
confirm its voltage range,
continuous power requirements,
startup current, and
connector compatibility.
Application 2 – Power Other Voltages with a DC-DC Converter
The battery's 30–42V
output can be converted
to other DC voltages
using a suitable
DC-to-DC power converter.
This makes the HL3633B
a flexible power source
for systems that need
a different regulated
DC voltage.
For example, a properly
selected converter may
provide regulated 12V,
24V, or other DC outputs.
Converter Compatibility:
Select a DC-DC converter
that accepts the full
30–42V battery input
range and is rated
for the required
output power.
Allow for conversion
losses and startup
current requirements.
Application 3 – AC Power with an Optional Inverter
The HL3633B can also
be used with a compatible
36V DC-to-AC
power inverter
to supply AC power
for suitable equipment.
A compatible inverter
converts the battery's
DC output into
AC electricity.
Example battery and AC inverter setup.
Inverter and battery carry handle
are not included.
Choose an inverter
that accepts the
complete 30–42V
battery voltage range.
The inverter's output
power must also be
compatible with
the battery's discharge
capability and
recommended application
power limits.
Inverters and their
connecting cables
are sold separately.
Application 4 – Alternative to Three 12V Lead-Acid Batteries
The HL3633B may be
considered as a
lighter-weight
alternative to
three 12V lead-acid
batteries connected
in series in a
compatible 36V system.
Its high energy density
allows a substantial
amount of energy
to be stored in
a smaller package.
The HL3633B weighs
approximately 13 lb,
compared with substantially
heavier lead-acid
battery arrangements.
It also eliminates
the need for
three separate
12V batteries and
their series
interconnection cables.
Replacement Compatibility:
Do not assume every
36V lead-acid system
can accept a lithium-ion
replacement directly.
Check the motor controller,
voltage limits,
charging system,
current demand,
mounting arrangement,
and wiring.
Use the lithium-ion
battery's approved charger.
