Baintech 12V 75Ah Compact Lithium Battery is constructed using the latest lithium iron phosphate cells. These prismatic cells are the highest quality in a metal hard case. The battery has an inbuilt Battery Management System (BMS).

At just 9kg, this rugged light weight battery has around double the usable capacity at up to a quarter of the weight of the comparable lead acid or AGM equivalent.

The 1275-SP provides up to 100A of continuous discharge current and 70A charge current and can be placed in parallel to increase storage capacity. The battery has a grey Anderson plug for easy and convenient connection.

The strong aluminum outer enclosure delivers a safe, lightweight and powerful unit which is the perfect building block for next generation battery systems.

Why Lithium?

Lithium batteries provide more usable capacity than lead acid batteries. Deep discharging does not affect the life of a lithium battery the way it does with lead acid batteries. You can use the battery longer before needing to recharge, without damage to the battery.

Cost Effective Over Life Cycle

When considering the usable capacity and lifespan of lithium batteries, they work out cheaper than lead acid. When you add the cost and inconvenience of refitting new lead-based batteries every few years the total cost of ownership over the long term is far better with lithium batteries.

Longer life

Lithium batteries are rated for 2,000 – 5,000 cycles and much more if used carefully, giving you several times the life expectancy of standard lead acid batteries.


Lithium batteries allow you to pull far more amps out of the same size battery systems.


Lithium batteries are less than half the weight of the equivalent lead acid battery. Lithium batteries can be up to a third of the weight of the equivalent lead acid AGM battery. This is an important consideration for anybody who is mobile.

A 100Ah AGM deep cycle battery can be up to 38kg in weight, whereas the same size lithium battery can be less than 12kg in weight!

That means you can at least double or even triple the stored battery capacity on a RV, or alternatively use the reduction in battery weight to bring more water, or food or luggage on your trip.

Reducing weight in a RV helps to keep you under the tare weight, reduces aerodynamic drag which improves fuel efficiency while on the road.

Fast recharge

Lithium batteries charge more efficiently, and don’t require as many stages during charging. Therefore, they will charge faster, and hold more of the energy from solar panels and other charging device.



Quick Start Guide:

The Grey Anderson Plug can be used as input and outputs for charging and running loads. By using a parallel split lead you are able to run loads and charge your battery simultaneously.

NOTE – There are no internal fuses inside the battery so an external fuse must be used for each Anderson connector, 100A maximum. The internal BMS is designed for up to 100A continuous charge and 100A continuous discharge. Please consider this when connecting charging devices and loads

How to charge your 75Ah Battery

Charge sources could include: – External AC charger with grey Anderson connector; – External (regulated) solar charger with grey Anderson connector; or – External DC-DC charger with grey Anderson connector.

For connected chargers and devices, a grey Anderson plug must be used. Check to ensure the Anderson is correctly wired (positive and negative) and do not attempt to use any coloured Anderson other than grey.
