CBT

The CBT VB001 is a state-of-the-art lithium iron phosphate (LiFePO4) storage unit, specially developed for the requirements of campers, motorhomes and boats. With a huge storage capacity of 2200 watt hours (Wh) – which equates to around 172 Ah at 12.8V – it offers maximum self-sufficiency away from shore power connections.The highlight of this battery is the integrated Bluetooth interface. Using an app on your smartphone, you always have a complete overview of the state of charge (SoC), the voltage, the current flow and the temperature. The built-in Battery Management System (BMS) protects the valuable cells fully automatically and ensures a service life that exceeds that of conventional lead-acid batteries many times over.Highlights at a glanceEnormous capacity (2200Wh): With a calculated 172 Ah this battery provides enough energy to operate lights, water pump, fridge and inverter (for coffee machine/laptop) self-sufficiently for several days.Smart monitoring (Bluetooth): No more flying blind! Connect your mobile phone to the battery and see in real time how much energy is still available and how much is currently being used or charged.Integrated BMS (protection system): The BMS monitors every single cell. It protects against overcharging, deep discharge, overcurrent (short circuit) and overheating. At critical values, the battery switches off automatically to prevent damage.LiFePO4 technology (safest chemistry): Unlike lithium-ion batteries (NMC), LiFePO4 cells do not burn or explode if damaged. They are thermally stable and considered the safest lithium technology for mobile use.Weight advantage: Weighs only a fraction of a comparable lead-gel or AGM battery (approx. 50-60% weight saving). This increases the payload capacity of your motorhome.Cycle stability: Designed for >3000 cycles (at 80% discharge). With normal use, this corresponds to a service life of over 10 years, whereas lead batteries often have to be replaced after 2-3 years.Fields of applicationThe CBT VB001 is the ideal companion for:Motorhomes & camper vans: As a supply battery under the seat (under-seat installation often possible, check dimensions!) or in the double floor.Marine & Boats: As a consumer battery for on-board electronics (not as a starter battery for the engine!).Solar island systems: Efficiently stores the electricity harvested via solar panel during the day for the night.Mobile workshops: Power supply for tools and chargers in service vehicles.Assembly & safety instructionsCharging technology: Use a charger with a lithium curve (LiFePO4). Make sure your solar controller and charging booster are also set to lithium. Be sure to deactivate any "Recondition" or "Desulphation" programmes on old chargers, as the high voltage spikes can destroy the BMS.Temperature: Lithium batteries must not be charged below 0°C (the BMS usually blocks this). Discharging is possible down to approx. -20°C. Plan the installation location in the heated interior if you do winter camping.Installation position: LiFePO4 batteries can be installed upright or lying down (on the side) as they contain no liquid that could leak out.Wiring: Protect the battery directly at the positive terminal with a suitable fuse (e.g. MIDI or MEGA-fuse) suitable for your maximum consumption.Features ModelCBT VB001 Caravaning (LiFePO4) Technology**LiFePO4** (lithium iron phosphate) – safest type of lithium Nominal voltage**12.8 V** Nominal capacity**172 Ah** Energy contentapprox. **2200 Wh** (2.2 kWh) Max. discharge current**150 A** (continuous) / **200 A** (peak 3s) *(Sufficient for inverters up to approx. 1500W-2000W)* Cycle stability**> 3000 cycles** (at 80% discharge) Dimensions (L x W x H)approx. **357 x 338 x 152 mm** (special size for seat console) *(Please measure your console before purchase!)* Weightapprox. **19.0 - 21.0 kg** (extremely light for 172Ah) Connectivity**Bluetooth 4.0** (app for iOS/Android) FAQs about the CBT VB001Which app do I need for Bluetooth?These batteries usually use apps such as "Xiaoxiang BMS", "Overkill Solar" or a specific "CBT App". A QR code for download is usually found on the case cover or in the instructions.Can I operate my inverter (1500W) on it?Yes, to a certain extent. 1500 watts at 12V means approx. 125 amps of current flow. Check the VB001 data sheet to see if the BMS allows a continuous discharge current of at least 150A. Many 172Ah batteries can handle this without any problems, but some are limited to 100A (which equates to only around 1200W).Can I mix this battery with an AGM?No. Never directly connect lithium batteries with lead/GEL/AGM batteries. The voltages and internal resistances are too different. Use the CBT VB001 as the sole supply battery.

The CBT VB007 is a powerful 120Ah lithium iron phosphate (LiFePO4) battery specially designed for mobile use in motorhomes, vans and marine applications. With an energy capacity of 1536 watt hours (Wh) it offers the ideal balance of compact design and high endurance.This model is the perfect replacement for conventional 95Ah or 100Ah lead-acid/AGM batteries. You not only get more usable capacity (as lithium can be discharged to almost 100%, lead only to 50%), but also save a massive amount of weight. Thanks to the integrated Bluetooth monitoring you have full control over the charge status and health of your battery at all times via smartphone app.Highlights at a glance1536Wh (120 Ah) capacity: Provides sufficient reserves for lights, TV, water pump and charging small appliances over a long weekend without shore power.Smart Bluetooth control: The integrated Bluetooth module sends data such as voltage, current, state of charge (SoC) and temperature directly to your smartphone. No separate battery computer (shunt) required!Integrated BMS (Battery Management System): The electronic protection circuit monitors each cell individually and protects against:Over-charging (over-voltage)Deep discharge (under-voltage)Overcurrent / short circuitOvertemperatureLiFePO4 technology: Safest lithium technology on the market. No risk of fire in the event of mechanical damage, thermally stable and extremely durable.High cycle stability: While a lead-acid battery degrades massively after approx. 500 cycles, the CBT VB007 over 3000 cycles (at 80% depth of discharge). This corresponds to a service life of often over 10 years.Weight saving: Weighs only approx. 12-14 kg compared to the approx. 28-30 kg of a comparable AGM battery.Fields of applicationMotorhomes (under-seat mounting): Due to the 120Ah size, this battery often fits perfectly under the passenger seat of common base vehicles (e.g. Fiat Ducato, VW Crafter) where space is at a premium.Boats & Marine: Power supply for navigation, lights and refrigerator (trolling motors only after checking the max. discharge current).Camping & Solar: Ideal storage for mobile solar systems.Assembly & safety instructionsCharge setting: Set your charger (EBL, solar regulator, charge booster) to "LiFePO4" or "Lithium". The final charging voltage should be 14.4V to 14.6V. The float voltage should be 13.5V - 13.8V.Winter operation: The BMS protects the battery from charging in freezing temperatures (< 0°C). Discharging is possible, but charging is not in order not to destroy the cells.Fuse: Install a suitable main fuse (e.g. 125A or 150A) as close as possible to the positive terminal of the battery. Features ModelCBT VB007 Caravaning (DIN standard) Technology**LiFePO4** (lithium iron phosphate) Nominal voltage**12.8 V** Nominal capacity**120 Ah** Energy content**1536 Wh** (approx. 1.5 kWh) Max. continuous discharge current**100 A - 150 A** (depending on model, BMS limited) *(Sufficient for coffee machine/hair dryer up to approx. 1500W)* Cycle stability**≥ 3000 cycles** (at 80% DOD) Dimensions (L x W x H)approx. **353 x 175 x 190 mm** (DIN H8 / L5 standard size) Weightapprox. **12.0 - 14.0 kg** (comparison lead: approx. 26 kg) Connectivity**Bluetooth 4.0** integrated (app monitoring) FAQs about the CBT VB007Does this battery fit under the seat of a Fiat Ducato?Very likely yes. The 120Ah (1536Wh) class is often dimensioned (approx. 353 x 175 x 190 mm, similar to H7/L5 standard), so that it fits horizontally or vertically under the swivel consoles. Please measure your available space before purchase, as seat consoles may vary.Do I need a charging booster?Recommended. If you want to charge the battery while driving using the alternator, a charging booster (B2B charger) is essential for modern Euro 6 vehicles. But even in older vehicles, the booster protects the alternator from overheating, as lithium batteries can draw very high currents.Does the app show how long the battery will last?Yes. The BMS calculates the remaining runtime in hours and minutes based on current power consumption. This makes energy management on holiday very easy.
