3. This is a 48 Volt class battery which may be used with 48V class Inverters, Chargers, and
Solar Charge Controller.
The nominal voltage of this battery is 51.2 Volts.
The Recommend Charge Voltage is 56.8 Volts, with a Float of 54.0 Volts, and a Battery
Cutoff Voltage of 48 Volts or higher.
Certain inverters such as some EG4, MPP Solar, Sun Gold Power, Rich Solar, and others will
require a Battery Float Voltage of 56.0 Volts.
If your inverter or Solar Charge Controllers seems to stop charging the battery at 54 Volts,
set the Float Voltage to 56.0 Volts.
Only 48 Volt Inverters, 48 Volt Solar Charge Controllers, or 48V LiFePO4 chargers may be
used to charge this battery.
Do not reverse the polarity when connecting to the battery terminals, positive (+) must be
connected to positive and negative (-) to negative.

Never connect AC, of any voltage, such as from a wall outlet to the battery terminals.
An appropriate 48V inverter, charger, or solar charge controller must be used.
Do not expose the battery to water, excessive humidity, excessive temperatures in excess of
105F, to oils or acids, or to direct sunlight.
Do not drill into the battery case, or weld to the battery case.
4. The battery may be oriented vertically, horizontally, or on its side.
We do not recommend setting the battery upside down.
The battery comes with a nice 4-wheel dolly with locking wheels.
Please consider using this dolly. If desired, remove the sides of the wooden battery case,
ensure that the dolly wheels are locked in place, leave the dolly on the bottom of the
battery, then, with help, then lift one end of the battery so that the battery rests on the
dolly.
5. The two short DC Power Cables included with the battery should only be used if you will be
drawing no more than 50 amps from the battery.
If will be using a 3,000 watt or higher inverter, these cables must not be used.
Use 2/0 AWG Pure Copper battery cables, with very high strand count.
You may also use 4/0 AWG Pure Copper battery cables.
To make this easy, we recommend using www.batterycablesusa.com
Use the Marine Grade, UL Listed battery cables, with 5/16” copper lugs for the battery ends.
If you are using a Victron Lynx Power End or Distributor busbars, also use 5/16” copper lugs.
00 Gauge (2/0 AWG) Marine Grade Tinned Copper Battery Cable UL 1426 Flexible with ends
(batterycablesusa.com)
0000 Gauge (4/0 AWG) Marine Grade Tinned Copper Battery Cable UL 1426 Flexible with ends
(batterycablesusa.com)
We highly recommend using the above cables to prevent problems, either immediately, or
in the future. You may call us for advice.
The recommended DC Power Cables for most installations are 2/0 AWG
(Pronounced Two-Aught), using 5/16” Copper Cable Lugs.
Cable Lugs are Cable Terminators (ends) that allow the battery cable to be bolted to the
battery terminal.

TROPHY BATTERY, LLC
Page 3 of 14
There are two positive battery terminals, and two negative battery terminals.
For the connection to the battery terminals, 5/16” cable lugs are best, but 3/8” may be
used.
6. Never connect our batteries in series.
Never connect + to –as this is a series connection.
If connecting multiple batteries, the batteries must be connected in parallel.
Parallel connections are + to + and –to –. (Positive to Positive, Negative to Negative)
7. The best way to connect multiple batteries, if you are using more than one battery,
is to use professional copper busbars.
When using busbars, you use equal length battery cables from each battery to the busbar.
Then you connect your inverter(s) to the busbars. If you have multiple inverters, then each
of the cables to the busbars must be the same length.
Victron makes high quality 1000 amp busbars, called Lynx Power In and Lynx Distributor.
The Lynx devices are expandable, as each unit can bolt to the next.
One Power In has connections to enable four batteries to be connected.
One Distributor also has four connections.
Trophy Battery sells Victron gear, so you may purchase the Lynx busbars from us or other
sources. The Lynx busbars are two busbars in one, one for positive and one for negative.
The Lynx Distributor is a fused busbar, thus you can economically add Mega-Fuses to
protect your inverters or solar charge controllers.
Please feel free to call us for guidance.
The Lynx busbars use M8 –5/16” terminals.
Blue Sea Systems also makes quality busbars.
Avoid at all costs, a cheap, undersized busbars or a busbar that contains brass instead of
copper. These will not work and are a waste of money.

8. When using Multiple Inverters, it is necessary to combine all batteries together, using
busbars, to make one large battery bank, and then connect all inverters to the busbars.
9. Certain Inverters, such as Sol Ark 12K and Sol Ark 15K use 3/8” terminals, so your busbar to
inverter cables must have 3/8” terminals for the inverter ends.
The Sol Ark 15K has dual DC input terminals, two + and two –and you should use two
battery cables to power each Sol Ark 15K inverter.
You may call us for guidance.
10. When you have multiple batteries, you need to have a communication cable from each
battery to the next. You should connect one each of the cable to either of the 485-1 or
485-2 ports of one battery to either 485-1 or 485-2 port of the next battery.
We provide these communication cables with the batteries. But, if you need a longer cable,
please use a straight-thru cable, not a cross-over cable. Use an Ethernet cable, with RJ45
connectors, preferably CAT5e.
When connecting multiple batteries together, it is best to use the same brand and model of
batteries together.
There are cases where it is ok to connect a different brand or model of batteries together.
Please call us so we can advise you in advance.
If you have more than 16 batteries, you can set up one bank of 16 and then have another
bank of up to 16 batteries. Other arrangements are possible, such as 20 batteries in two
banks of 10 each.
If you have a different brand of battery, or a different model of battery, you will need to
break the battery to battery communication cabling. Please call us for advice.
Different types of batteries generally cannot communicate with each other, thus omit the
communications cable between them.
11. The battery has a push-button On-Off Switch to turn the battery on or off.
This turns on the battery’s electronics, the battery’s Battery Management System.
The large circuit breaker is labeled Breaker, and this is to connect or disconnect this one
battery from the load or from charging.

12. If the battery is in storage, or not being used, it is necessary to charge it a little, 5 to 10%
every three months. This is necessary to keep the electrolyte in the battery liquid. Do not
go by battery voltage or state-of-charge to determine if the battery needs to be recharged
after 3 months.
13. This battery is compatible with Victron 48V Inverter/Chargers and 48V Solar Charge
Controllers.
If you have a Cerbo GX as part of your Victron System, please order a Victron Type A cable
to go from the CAN/485 Port on the battery to the BMS CAN port on the Cerbo GX.
If you have a Cerbo S GX, it is possible to use it instead of a Cerbo GX under certain
conditions. Please call us for advice. If you have any VE.CAN devices that you need to
connect and you need to also connect to the battery, then you must have the Cerbo GX and
not the Cerbo S GX.
The Type A cable is labeled “BMS- Battery”on one end, plug this end into the CAN/485 port
on the battery.
Plug the end labeled VE.CAN to either BMS-CAN Port on the Cerbo GX, and not a VE.CAN
Port! Plug a Victron Blue Terminator into the other BMS-CAN port.
If you need assistance, please call us. Trophy Battery is an authorized Victron Dealer and
can provide most any Victron device.
14. This battery has Bluetooth communications so you can easily see the status of your battery.
The iOS/Android app is named yBMS and can be downloaded to you iPhone/iPad or
Android device.
15. This battery is designed to communicate with Sol Ark Inverters. Connect Straight-Thru
Ethernet Cable from the battery’s CAN/RS-485 port to the CAN port on your inverter.
If you have any questions, please call use.
For Sol Ark, please set the option to use Battery Cutoff by Voltage and not State-of-Charge.
