Feature Highlights
FEATURE HIGHLIGHT: Adaptive Loading
The Adaptive Loading feature adjusts the charger’s output level automatically and dynamically
on each output bank. This function allows more charging power goes to the more depleted bat-
tery, and less power goes to the battery that is closer to full charge.
In Scenario 1 (left chart), the two batteries have a similar state of charge. The Turbo ME2
charger allocates approximately even 50% of its total output to each battery. In Scenario 2 (right
chart), the first battery is close to full charge, but the second battery is deeply depleted. In this
case, Adaptive Loading allocates 10% of its charging amperage to the first battery and the rest
90%* to the discharged one.
In both scenarios, the charger uses its full output - maximum amperage, unlike chargers with
fixed output-per-bank, the Turbo ME2 charges all connected batteries in the shortest time pos-
sible.

Feature Highlights
battery’s from self-discharge.
At the first stage (Bulk), the charger provides its maximum constant current for fast charging.
The battery’s voltage increases as it absorbs the charge. When the battery voltage reaches
14.5V (Lead Acid /AGM mode), it’s approximately 85% recharged. The charger then moves to
the second stage.
At the second stage (Absorption), the charger continues to charge the battery at 14.5V (Lead
Acid / AGM mode). The charging current drops as the battery charged up to 100%. When the
batteries reach full charge, the charger then moves to the third stage.
At the third stage (Monitor / Float), the charger first goes to idle (no Float charge) while monitors
the batteries’ state of charge. If the voltage of battery #1 (battery connected by output #1) falls
below 12.5V, the charger restarts a new charge cycle. After a set idle period, the charger be-
gins to apply float voltage at 13.4V (Lead Acid / AGM mode) and continues to monitor. It is safe
to keep the charger connected to the battery indefinitely to maintain the battery’s full charge.
Turbo ME2 charges a battery in three sequential stages: Bulk, Absorption, and Monitor / Float.
This method is proven to bring a battery to its fullest charge, as well as maintain a fully charged

Installation
The Powermania Turbo ME2 series charger is designed to be mounted onboard a vehicle or
watercraft. Please refer to the illustration on the next page for the optimal mounting orientation.
The top row LED lights should line up horizontally at the top and the output cables at the bottom
of the charger. This orientation optimizes air ventilation during operation. Follow these instruc-
tions for a proper charger installation:
1. Select a well-ventilated area where there are at least 8 inches of clearance around the
charger. Make sure the mounting surface can firmly support the charger with the provided
screws. Do NOT install the charger near any combustible or flammable materials such
as a fuel tank or a compartment filled with gasoline vapors.
2. Make sure the charger’s DC output cables can reach all batteries from the mounting loca-
tion. Do NOT lay cable or any wire in direct contact or adjacent to the charger’s case
as the charger could reach a high temperature and possibly cause a fire hazard to the
cable.
3. If the DC cables are not long enough, they may be extended by adding Powermania tool-
free DC extension kit (available in 5’, 10’, or 15’ length) - Accessory P/N 10521 (5’), 10522
(10’), and 10523 (15’). If it is necessary to cut and splice the wires, use only UL certified
marine grade 14 AWG for 6 Amp and 8 Amp models, and 12 AWG for 15 Amp and 20 Amp
models. Each splice should be covered by adhesive lined / dual wall heat shrink tube to
prevent corrosion at the joints. The splicing should be made between the fork of the cable
and the fuse holder so that the fuse stays within 6” of the battery terminals. Do not add
more than 15’ of DC cable extension. Do NOT lay cable or any wire in Making any modifi-
cation to the factory-equipped cables will void the warranty.
4. Support the charger and position it on the tentative mounting area. Use a pencil to mark
the position of each mounting hole.
5. Use 1/8” drill bit to drill on the marked position.
6. Align the charger to the drilled holes, and then secure the charger with the provided
screws.

Select Battery Type
SELECT BATTERY TYPE
The Battery Selector has three settings. From left to right, the first position (factory setting) is for
charging most of Flooded Lead-Acid and AGM batteries. Set the selector to the middle position
(14.6CV) for charging Lithium Iron Phosphate (LiFePO4) batteries*. The right position (AGM+) is
for charging Thin Plate Pure Lead (TPPL) AGM battery (Odyssey and Northstar AGM’s). If there
is more than one battery type, choose a profile with charging and maintaining voltages fall in
ranges of all the connected batteries. Refer to page 9 for voltages in different settings.
* Please consult Lithium battery manufacturer for charging compatibility. When setting up a
charging system for LiFePO4 batteries, it is recommended using a dedicated Turbo ME2 charger
for a single application. For example, use a dual-bank charger dedicated for a 24V (two 12V in
series) Lithium battery set up. Do NOT use the same charger for multiple lithium battery applica-
tions such as mixing trolling motor batteries and starting batteries - even if they are all LiFePO4
batteries.
To change Charging Profile Setting:
1. Make sure the charger’s power cord is
unplugged from the power outlet.
2. Loosen the screws from the battery
type selector.
3. Carefully pull the battery selector
straight out from the charger.
4. Place the battery selector back to the
charger with the desired battery type
position.
5. Secure the screws back to the battery
selector.
Do NOT use any other screws that are not provided by Powermania to tighten the selector cap.
Using unauthorized screws could damage the charger and result in serious personal injury.

DC Wiring Connection
CONNECT THE DC CABLES
The following pages demonstrate proper DC wiring configurations for Powermania Turbo ME2
series chargers. When making DC connections, make sure connecting the same set of positive
and negative connectors to the same 12V battery. The red wires are positive (shown as grey
color on the diagrams), and the black ones are negative. It is critical not to mix up polarity when
making a connection.
ALL of the charger’s output cables must be connected to batteries. Never leave any output
unconnected. If there is a spare output left unused, double up the spare output to a 12V battery
that’s already been connected by another one.
Connect the charger’s first output (output #1) to the main house battery, or the (deep cycle)
battery that’s typically got most depleted. Output #1 is located next to the AC cord.
Please refer to the following legend used in the connection diagrams.

Troubleshooting
BATTERY ISOLATION TEST
The Battery Isolation Test could help identify whether an error is caused by the charger or by
one of its connected batteries, which could be defective.
1. Check all inline fuses on all outputs.
2. Combine all of the charger’s outputs to just one 12V battery - choose a battery that is NOT
previously connected by output #1.
3. Plug in the AC power cord and observe if the charger runs a normal charging cycle and
brought the connected battery to full charge.
4. Repeat the same test to another 12V battery.
5. If the charger completes a full, normal charging cycle in only one of the two tests, it may be
a battery’s defect. Bring that battery to a battery shop for a further load test.
6. If the charger performs full, completed charging cycles in both tests, it may be a connec-
tion error from the previous set up.
7. If the charger returns error LED in both tests, contact Powermania to check for warranty
coverage.
The Powermania Turbo ME2 charger requires no specific maintenance. However, it is
recommended to do the following to ensure reliable and optimal performance from your battery:
• Regularly clean battery terminals and charger’s output ring terminals with baking soda and
tighten all DC wiring connections.
• Regularly check and maintain proper battery electrolyte level following battery manufac-
turer’s instructions.
It is recommended that you keep the charger plugged in to maintain a proper charge level of the
