HiTech 150Ah LiFePO4 Lithium Battery with Bluetooth

HiTech 150Ah LiFePO4 Lithium Battery with Bluetooth

The HiTech 150Ah Lithium Battery is a mid-capacity LiFePO4 upgrade for caravans and motorhomes replacing traditional AGM or lead-acid setups. Lithium batteries offer significantly more usable capacity (up to 100% depth of discharge vs around 50% for AGM), a much longer service life, and lighter weight for the same footprint. Built-in Bluetooth monitoring lets you check state of charge, voltage and remaining capacity directly from your smartphone, without needing to fit a separate battery monitor.

Key Features

• 150Ah capacity with up to 100% usable depth of discharge — far more effective capacity than a same-rated AGM battery
• LiFePO4 chemistry — stable, non-flammable and long-lasting
• Bluetooth monitoring via mobile app — check state of charge, voltage and capacity from your phone
• Rated for up to 4,000+ cycles at 100% depth of discharge — a very long service life
• IP67-rated sealed ABS enclosure for dust and moisture resistance
• Integrated BMS protecting against overcharge, over-discharge, overheating and short circuits
• Accepts high charge currents for fast recharge from solar or a DC-DC charger

How do I know this will fit / suit my setup?
Check the dimensions, weight and terminal type listed in the Specifications tab against your existing battery box and wiring. If you're unsure whether this battery suits your caravan or motorhome, contact us and our team can help you confirm compatibility.

What's the warranty?
This battery carries HiTech's standard 12-month manufacturer warranty. Contact us for full warranty terms and conditions.

Can I use a standard charger with this lithium battery?
Lithium batteries require a charger with a lithium charging profile. Using a standard lead-acid charger can damage the battery or trigger the battery management system. Ensure your charger, solar controller and DC-DC charger are all set to lithium mode.

Can this replace my existing AGM battery directly?
In most cases yes, provided the physical size fits your battery box and your charging equipment supports a lithium charge profile. Check the dimensions and weight in the Specifications tab before ordering.

Does this battery have a heater for cold-weather charging?
No, this model does not include a self-heating element, so like most LiFePO4 batteries it should not be charged below 0°C. If you regularly camp in freezing conditions, consider a heated lithium battery instead.

How do I know what capacity I need?
Calculate your daily power consumption in watt-hours (Wh) by adding up the wattage of each appliance multiplied by hours of use, then divide by 12V to get Ah. For lithium batteries, size to around 1.25x your daily consumption to allow for a safe 100% depth of discharge. Contact us for help sizing your system.
