70Ah-M8 LifePo4 13.2V Extralight battery 6.4kg - Gs Audio - CCA:2500A

70Ah LifePo4 13.2V Extralight Battery 6.4kg - Gs Audio - CCA:2500A

High-performance ultralight battery for sports car audio systems and starters.

GS Audio's new generation of ultralight LiFePO4 batteries is designed to offer maximum performance while taking up the minimum possible space.

The main distinguishing features compared to other LiFePO4 lithium batteries are:

1) very high current output, thanks to multiple internal BMSs;

2) special ultralight cells with high current delivery capacity.

These batteries can also be used on RVs and in situations requiring energy storage, but they best express their potential on everyday cars with sound systems, winches, or other high instantaneous electrical loads, or for those who simply want to reduce weight.

By adding ISO M8 POLES to the purchase, the battery can be installed perfectly using the car's original clamps. Remember to allow for an extra 20 mm in the height of the battery.

Currently available sizes are:

20Ah-M5 (weight 2.6 kg) - box with screw attachment poles

30Ah-MINI ISO (weight 3.5 kg) - rectangular with small poles

35Ah-ISO (weight 4.3 kg) - ISO box with regular poles

35Ah-M6 (weight 4.0 kg) - box with screw connection poles

70Ah-ISO (weight 6.4 kg) - ISO box with regular poles

70Ah-M8 (weight 6.4 kg) - box with poles screw connection

100Ah-ISO (weight 9.1 kg) - ISO box with regular poles

GS Audio LiFepo4 batteries should not be mounted in systems that have other types of batteries mounted (AGM, lead acid, LTO, ECC....).

If you decide to mount Lifepo4 batteries you must change all the batteries in your car.

GS Audio LiFepo4 batteries are made with huge quality cells, to have a high inrush current required in the car audio world, without having overheating or fire problems. 

These batteries have a very low self-discharge; however, in the winter months or for non-use longer than 30 days, charging with our LIFEPO4 chargers is recommended to stabilize the cells.

The cells are immersed in fireproof foam to preserve their qualities even after shocks, without causing fire or damage to them.

With an average specific gravity of 153Wh/kg, they are among the lightest on the market compared to other technologies!

 - LTO (titanate) ~ 70 Wh/kg

 - Lead AGM ~ 38 Wh/kg

Batteries with lifepo4 technology have a life of about 2,000 charge and discharge cycles, about 6 times that of lead-acid batteries, which is about 300 cycles.

In addition, respite conventional lead-acid batteries, LiFepo4 batteries do not contain heavy metals or acids that are harmful to the environment.
