Description
SKANBATT V2 Lithium HEAT Battery 12V 480Ah 150A BMS - 8 year warranty!
NEW! 12V 480Ah (!) in a special box designed to be mounted under the seat of Fiat Ducato-based motorhomes etc.. This battery provides the most capacity in relation to weight and volume - great if you want the most capacity, for example, in your motorhome where the battery must be mounted under the seat.
High energy density / low weight - Skanbatt High Density (HD)
HEAT-480150BS is a brand new battery where the highest possible energy density/lowest possible weight is the main focus (Skanbatt HighDensity), in addition to well-known Skanbatt quality, functionality, long warranty period and top performance. The battery is ideal for use in motorhomes, boats, camping, industry and other power-hungry applications where space and weight are important. For cabins, where energy density is less important, we recommend our Ultra series (12V) or the Skanbatt Powerwall - which has functionality especially suited to cabins.
Designed for motorhomes
This battery has special dimensions to fit under the seat of Fiat Ducato-based motorhomes (where there is already room for two 95Ah lead-acid batteries), but with the highest possible capacity in the smallest possible volume and weight. If you install one of these under the seat, you'll get 480Ah of usable capacity - about the same usable capacity as you'd get if you installed 50% with about 11 95Ah lead-acid batteries. 95Ah lead batteries - but only approx. 42 kg lithium batteries against approx. 290 kg lead batteries. Note that on some motorhomes you have to make some adjustments to make room.
External on/off switch
A short cable is included with an on/off switch at the end, which can be used to turn off the battery when the device is to be stored over time.
Built-in automatic security system
The battery has an advanced built-in battery management system (BMS) that can withstand up to 200A continuous load (very briefly up to 450A for up to 5 seconds). We normally recommend a lower continuous current draw due to potential hot spots in the polsko - 150A is a reasonable limit. The battery has threaded holes for M8 bolts. The battery computer is fully automatic, and protects the battery from:
- Discharge/overcharge
- Too high a temperature
- Charging in the cold (has a built-in, automatically controlled heating element)
- Short circuit
- Overloading
- Skewed internal cells (automatic, active balancing of the cells)
Bluetooth module with battery monitor and APP support
The battery computer has a built-in Bluetooth module as well as an internal battery monitor (shunt-based) that displays:
- Remaining time and capacity in %SOC (State of Charge) and ampere hours.
- Consumption/charging in amps and watts (and status) (The resolution of the measurements is 2A to 220A, consumption beyond this is not registered)
- Internal temperature in the battery
- The voltage on each cell module
- Number of cycles the battery has been used ("battery mileage") - 1 cycle = one full discharge and recharge
You can find the app here: (NB! This battery uses a different app than our other lithium batteries: "V2 Battery")
Iphone: https://apps.apple.com/no/app/skanbatt-v2/id1620104098
Android: https://play.google.com/store/apps/details?id=no.skanbatt.battery.app
A new feature of this app is that you can collect battery information in both series and parallel, so that the app shows total information on the entire battery pack. The app also has autoconnect so that it can always connect automatically to your battery or battery bank.
Battery charger requirements
The battery can be charged with most electronic chargers, but it is important that the final voltage reaches 14.4-14.6V to achieve the highest capacity. LiFePO4 batteries do not normally require trickle charging, but most devices have current draw - so it's best to use a charging program where the charger regulates down to 13.5-13.8V when the lithium battery is fully charged. Which charging program is best will vary from charger to charger - contact us for assistance on what works best with your particular charger. For this battery, we recommend that it is charged with a total charging current of at least 30A in order to operate the heating system in freezing temperatures.
Parallel and series connection
This battery can be connected in parallel for increased capacity. For parallel connection, we recommend balanced connection and individual fuses per battery. For larger solutions, please contact us for design assistance. The battery should not be connected in series.
Starting engines and other large consumers
The battery is manufactured as a deep cycle battery and should not be used as a starter battery. In some cases, thrusters, winches and other equipment with high consumption can be used if the total capacity in the bank is large enough, and the solution is designed / mounted correctly for this. Please contact us for assistance if you have any questions about this.
Automatic, built-in heating system for charging lithium in the cold
The battery has a built-in heating system that allows it to be charged even in sub-zero temperatures in winter. The 100% is self-controlled and you don't need to think about it. The heater is activated when you try to charge the battery in sub-zero temperatures. The battery will then close for charging, activating the heating foil. When the battery has reached an internal temperature of approx. +5 degrees Celsius, the heater is deactivated and the battery reopens for charging. At approx. -20 degrees Celsius ambient temperature (and battery temperature), it will take just over an hour to warm up the battery until it accepts charging - the temperature rises approx. 0.25 degrees Celsius per minute when the ambient temperature is so cold.
Technical data:
- Nominal voltage: 12,8V
- Normal quiescent voltage at 100% SOC: approx. 13.2-13.35V
- Rated capacity: 480Ah
- Amount of energy fully charged: 6144Wh
- Self-discharge approx: <5% per month.
- Max number in series: 1 (cannot be connected in series)
- Maximum number in parallel: No limit as long as it is connected balanced and with individual fuse per battery.
- Max discharge current: 150A
- Max peak current: 450A <5sec
- BMS cut off voltage: 10V
- Protected against short circuit
- Max charging current: 150A (recommended <100A)

- Heater consumption (during charging): approx. 240 watts (17.5A) until the battery reaches approx. +5 degrees Celsius internal temperature.
- The heater closes automatically when the battery is heated (+5 degrees Celsius), and the battery then opens for normal charging.
- The battery monitor is shunt-based and measures between 2 and 200A consumption. Consumption below 2A is not shown in the app and does not change the SoC. Possibly. Smartshunt solves this.
- Minimum recommended charger: >=30A to operate the heating system in freezing temperatures.
See the data sheet for more information.
NB: All batteries (including lead-acid batteries) must be charged to 100% with a suitable charger before use. (This can be your built-in charger in your boat or motorhome).
NB: The space under the seat is tight, so small modifications may need to be made to accommodate the battery, and the base may need to be removed.
