Feature Highlights
FEATURE HIGHLIGHT: Adaptive Loading
The Adaptive Loading feature adjusts the charger’s output level automatically and dynamically
on each output bank. This allows more charging power goes to the more depleted battery and
less power goes to the battery that is closer to full charge.
In Scenario 1 (left chart), the two batteries have similar state of charge. The Turbo MV2 allocates
approximately even 50% of it total output to each battery. In Scenario 2 (right chart), the first
battery’s is close to full charge, but the second battery is deeply depleted. In this case, Adap-
tive Loading allocates 10% of it charging amperage to the first battery and the rest 90%* to the
discharged one.
Note that in both scenarios the charger uses its full output - maximum amperage, unlike char-
gers with fixed output-per-bank, the Turbo MV2 charges all connected batteries in the shortest
time possible.
* Due to safety precautions, the maximum current is limited to 25 Amp per output.

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
battery is fully charged, 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 MV2 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 MV2 series charger is designed to be mounted onboard a vehicle or
watercraft. The chart below shows the proper orientation of the mounting position. The top
row LED lights line up horizontally at the top and the output cables at the bottom of the charger.
This orientation optimises air ventilation during operation. Follow these instructions for a proper
charger installation:
1. Select a well-ventilated area where there are at least 8 inches of clear air space around the
charger.
2. Make sure the charger’s DC output cables can reach all batteries from the mounting loca-
tion.
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 the wires are to be cut and connected to a third party extension
cable, use marine grade 12 AWG for 12 Amp and 20 Amp models, and 10 AWG for 30 Amp
and 40 Amp wires. 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. Making any modification to the factory-
equipped cables will void the warranty.
4. Do not mount the charger directly on carpeted, upholstered, or varnished surfaces. If the
charger is to be mounted on these surfaces, it is mandatory to use the included Raiser
Footing (or the optional Flange Footing) to raise the charger bottom from direct contact of
the mounting surface.
5. Make sure the mounting surface can firmly support the charger with the provided screws.
If through bolt mounting is desired, use optional Flange Footing accessory and mount the
charger using #10 bolts and nuts.
6. Support the charger and position it on the tentative mounting area. Use a pencil to mark
position of each mounting hole.
7. Use 1/8” drill bit to drill on the marked position.
8. Align the charger to the drilled holes, and then secure the charger with the four provided
screws.

DC Wiring Connection
CONNECT THE DC CABLES
The following pages demonstrate proper DC wiring configurations for Powermania Turbo MV2
series chargers. When making DC connections, make sure each set of positive and negative
connectors are connected to the same 12V battery. The red wires are positive (shown as grey
color on the diagrams) and the black ones are negative. Never connect a black wire (negative)
to a terminal that is connected with a red wire (positive).
ALL charger’s output cables must be connected to battery. Never leave any output uncon-
nected. If there is a spare output left unused, double up the spare output to a 12V battery that’s
already been connected by another output.
It is recommend to connect the charger’s first output (output 1) to main house battery, or
the battery that’s typically got most depleted. The first output set is located next to the AC
cord.
Please refer to the connector legend reference diagram which is used for all of the connection
diagrams:
EACH AND EVERY DC OUTPUT CABLE MUST BE CONNECTED TO A 12V

Troubleshooting
BATTERY ISOLATION TEST
The Battery Isolation Test could help identify whether an error is caused by the charger itself 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 AC power cord and observe if the charger runs a normal charging cycle and
brought the connected battery to full charge.
4. Move 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 to conduct battery test.
6. If the charger performs full, completed charging cycles in both tests, it may be connection
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 MV2 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.
