12V and 24V Lifepo4 lithium phosphate batteries

Treeline Power Systems only sells LiFePO4 batteries
Our LiFePO4 battery systems all come with an integrated BMS
The batteries are extremely easy to install, needing no additional components, unless installed in a vehicle system with alternator and engine starting battery.
The internal BMS will disconnect the battery in case of over discharge, over charge or high temperature.
Resilient:
A lead-acid battery will fail prematurely due to sulfation:
• If it operates in deficit mode during long periods of time (i.e. if the battery is rarely, or never at all, fully charged).
• If it is left partially charged or worse, fully discharged.
LiFePO4 batteries do not need to be fully charged. Service life even slightly improves in case of partial charge (we recommend 90%) instead of a full charge. This is a major advantage of LiFePO4 compared to lead-acid.
The resting discharge rate for a LiFePO4 battery under no-load conditions is about 3% per month, generally removing the requirement to use a battery tender during storage.
The BMS will cut-off the charge or discharge current when the maximum ratings are exceeded.
Efficiency:
• In real world applications (especially off-grid and hybrid grid solar), energy efficiency is of crucial importance.
• The round-trip energy efficiency (discharge from 100% to 0% and back to 100% charged) of the average lead-acid battery is 80%.
• The round-trip energy efficiency of a LiFePO4 battery is over 95%.
• The charge process of lead-acid batteries becomes particularly inefficient when the 80% state of charge has been reached, resulting in efficiencies of 50% or even less in systems where several days of reserve energy are required (battery operating in 70% to 100% charged state).
• In contrast, a LiFePO4 battery will still achieve 95% efficiency even under shallow discharge conditions.
The batteries can be connected in parallel. Series connection is not allowed (except Victron Smart batteries with a VIctron external BMS).

LiFePO4 (also called Lithium Iron or LIPO) batteries have a high storage capacity (both for their size and weight), are non-volatile, produce little heat in use and have a very long life.  They are ideal for residential, mobile and small commercial energy storage systems and their life cycle costs are less than half of lead acid batteries.  Lead is dead
