230Ah BullTron Polar 25.6V incl. Smart BMS with 250A continuous current, heating & Bluetooth App

Lithium battery for 24V battery systems, the battery can be used individually or in parallel. Ideal replacement for the 110Ah / 24V lead/AGM/GEL battery (identical dimensions in the original housing with 4 times the usable capacity) and suitable for use at temperatures from -30°C to 60°C. This 230Ah / 24V lithium battery replaces a GEL or AGM battery with a capacity of up to 460Ah / 24V and is significantly lighter than conventional lead-acid batteries.

Installation

Installation is incredibly simple: old battery out, new battery in, done. BMS, Bluetooth, active balancer, and heater – everything necessary is included in this lithium battery. Typically, existing chargers can be retained, but of course, we also offer chargers specifically designed for lithium batteries.

A prerequisite is that a battery-to-battery charging booster is installed in your vehicle. This limits charging currents to a safe value, thus preventing an overload of the existing wiring and fuse in the cable harness between the starter and leisure battery. You can find charging boosters in the following category: Charging Boosters

If needed, additional batteries of this model can be added and connected in parallel to increase capacity.

8 Reasons to Choose a BullTron Lithium Battery

• Developed and assembled in Germany. BullTron is a German manufacturer, so service and repairs also take place in Germany.
• Durability. With over 7,000 cycles (at 80% DOD), you will enjoy this lithium battery for a very long time.
• Super compact. Like all LiFePO4 batteries from BullTron, the 230Ah / 24V version is extremely compact and fits easily into the mounting space of previous batteries.
• Integrated powerful heating with the highest possible effectiveness and efficiency (extremely fast and completely even heating of all cells). The integrated heater starts at temperatures below 0°C when a charging current is applied. No battery discharge by the integrated heater.
• Extremely lightweight. At only 39.5kg, this battery is up to 85% lighter than a 460Ah / 24V lead-acid battery (same usable capacity). Weight savings = 224kg
• Excellent same-day service (battery problems are resolved within 1 day at Bulltron)
• 5-year German manufacturer's warranty.
• New, lighter, maintenance-friendly technology. Components are neither glued nor welded; the bolted housing can be opened – this promises easy and cost-effective repair, even far beyond the warranty period.

Optimal Lead-Acid Battery Replacement with up to 10 Times the Lifespan

BullTron LiFePO4 batteries are an optimal lead-acid battery replacement with all the advantages of lithium iron phosphate batteries. They offer a weight reduction of up to 85%, high energy reserves, and stable voltage even under extreme loads.
The batteries were specially developed to achieve an optimal balance of size, weight, performance, and lifespan. An extremely long lifespan is guaranteed even with regular deep discharge (4000 cycles at 100% DOD/depth of discharge or 7000 cycles at 80% DOD/depth of discharge) thanks to the latest lithium technology, making BullTron® batteries the optimal leisure battery.

System Voltage

The battery is suitable for 24V-48V systems.

• Parallel connection for 24V is possible (capacity increase)
• Series connection to 48V is not possible

Bluetooth / Smart

Battery data is fully transmitted to the Bulltron app (available for Android and iOS). If multiple Bulltron batteries are used, they can be grouped into one in the multi-app. The total state of charge of the battery bank is then displayed, and the data of each individual battery can still be viewed at any time.
If Bluetooth functionality is not desired, the Bluetooth module can be deactivated by unplugging the connector (accessible from the outside of the battery).

The new Bulltron app (free download from the App Store or Play Store)

The following information is transmitted from the battery to your smartphone/tablet via Bluetooth:

• State of charge in % / Remaining capacity in Ah *
• Total battery voltage
• Cell voltage
• Battery temperature
• Charge / Discharge in A and W
• Time until full / empty
• Heater status (on or off)
• Charge cycles
  * The values for state of charge in % and remaining capacity in Ah are calculated by the BMS and represent only a trend. If an exact capacity/state of charge display is required, an external SmartShunt or battery monitor must be integrated directly after the battery in the negative line.

Safest Lithium Technology (LiFePO4)

BullTron batteries use Lithium Iron Phosphate (LiFePO4) technology, currently the safest lithium technology on the market. All batteries consist of powerful and very durable (LiFePo4) cells and an integrated Battery Management System (BMS). The BMS permanently protects individual cells and the entire battery from over/under voltage, over/under temperature, overload, and short circuits (automatic shutdown without damage).
Premature battery failure due to external influences or incorrect use is effectively prevented by the BMS.
