Since 1926 Crown Battery has responded to the 'power' challenges and individual needs of industry leaders with the best available products and services in the field of heavy-duty commercial deep cycle batteries.
A company-wide dedication to quality control and continual improvement has earned Crown Battery the highest quality and service rating in the industry. We put more into our deep cycle batteries so you can get more out of them...
More performance, More Productivity with Less Maintenance. Nobody builds them like Crown, because no one else invests in the heaviest, thickest plates in the industry. Ours are over 10% thicker than our competitors.
Combine that with our proprietary PROeye and our low maintenance container - features that make battery maintenance predictable and efficient - and you've got a battery that's going to last longer and perform like no other.
Crown out-performs the competition in head to head tests over and over again.
It must be a matter of perspective. But we aren’t prone to exaggeration, the way some of our competitors are.
If you claim to have batteries that out-perform all others, an independent laboratory should confirm the findings. That’s the way we do it at Crown. Since 1926, that’s all we’ve done. And to us, it really isn’t a matter of claiming to be first in the industrial marketplace. But being the best. Some manufacturers are comfortable making exaggerated claims.
We’re comfortable making battery history… one customer at a time.
The heaviest, thickest plates in the industry. Thicker plates, heavier lead connections, and the most active lead material per ampere hour of rated capacity. And heavy means more lead, more active material. Which means more power. Longer life. Who would you put your money on? A lightweight battery? Or the heavyweight of the world. Crown.

|Storage||Batteries should be stored in a dry and cool area in an upright position.Store batteries on a solid surface that can safely accomodate their weight. Batteries can be safely stocked two or three layers high by using a secure stacking surface placed between each layer. When stacking batteries in layers, take care to secure battery terminals against short-circuit and to block and brace batteries that prevents any movement of the battery group. Please note that batteries need periodic stock rotation and service charging to ensure peak performance.|

New XTRA series - 3rd Generation MPPT - Budget Model
For 12V Solar System: 260W solar panel (60V for max input voltage)
For 24V Solar System: 520W solar panel (60V for max input voltage)
No Fan for silent operation, great for vans, boats or any live in spaces
Budget Model with no display. Can connect MT50 for remote display.
New XTRA series has Lithium battery support (set via PC cable only)
The XTRA tracer models have a current limiting function, you can connect twice the rated power to the controller so if your on a budget you can use a smaller controller with more panels so that you get more power in winter or low light but don't risk overloading the controller in the summer. The output will be limited to the max listed above.
New EPEver (Tracer) series is EPsolar’s third generation of MPPT controller.
XTRA series are advanced maximum power point tracking (MPPT) charge controllers, for off grid photovoltaic systems, with display unit.
In order to maximise the energy harvest from PV arrays and simultaneously minimise the power loss within a wide range of operating conditions, XTRA series apply an advanced smart algorithm which results in up to 30% higher efficient charging, compared to a conventional pulse width modulation (PWM) charge controller. Xtra series controller have limit protection function on charging current &charging power, as well as auto derating power operation at high temperature; the above protection ensure the stability of system even at exceeded rated PV power and over temperature conditions.
Protection class IP32 and isolated RS485 communication port further improve the controller’s reliability under different application requirements. XTRA series controllers incorporate a self-adaptive three-stage charging algorithm based on a digital control circuit, which eeffectively prolongs the lifespan of battery and significantly improve the system performance. It also has extensive electronic protection for overcharge, over discharge, PV&battery reverse polarity and etc. to ensure the sustainability and durability of the o-grid solar system.
¹ If using Lithium battery, customer should use “PCsoftware” to set the lithium battery parameters
² Ingress of solid objects:Protected against solid objects over 2.5mm
² Ingress of liquids: Protected against falling drops of water, if the case is disposed up to 15 from vertical
The BatteryProtect disconnects the battery from non essential loads before it is completely discharged (which would damage the battery) or before it has insufficient power left to crank the engine.
12/24V auto ranging
The BatteryProtect automatically detects system voltage
Programming made easy
The BatteryProtect can be set to engage / disengage at several different voltages. The seven segment display will indicate which setting has been chosen.
A special setting for Li-ion batteries
In this mode the Battery Protect can be controlled by the VE.Bus BMS.
Note: the Battery Protect can also be used as a charge interrupter in between a battery charger and a Li-ion battery. See connection diagram in the manual.
Ultra low current consumption
This is important in case of Li-ion batteries, especially after low voltage shutdown. Please see our Li-ion battery datasheet and the VE.Bus BMS manual for more information.
Over voltage protection
To prevent damage to sensitive loads due to over voltage, the load is disconnected whenever the DC voltage exceeds 16V respectively 32V.
No relays but MOSFET switches, and therefore no sparks.
Delayed alarm output
The alarm output is activated if the battery voltage drops below the preset disconnect level during more than 12 seconds. Starting the engine will therefore not activate the alarm. The alarm output is a short circuit proof open collector output to the negative (minus) rail, max. current 50 mA. The alarm output is typically used to activate a buzzer, LED or relay.
Delayed load disconnect and delayed reconnect
The load will be disconnected 90 seconds after the alarm has been activated. If the battery voltage increases again to the connect threshold within this time period (after the engine has been started for example), the load will not be disconnected.
The load will be reconnected 30 seconds after the battery voltage has increased to more than the preset reconnect voltage.
