Why a 48V 100Ah LiFePO4 Battery Fits a Telecom Site

A telecom cabinet does not need a bigger battery. It needs a battery that still has capacity after years of short charges, hot afternoons and the occasional deep discharge. That is the job of the SARBS 48V 100Ah LiFePO4 battery.

What SARBS publishes about this battery

On sarbs.net the 48V 100Ah lithium iron phosphate battery is described with a clear comparison to lead-acid. It offers up to ten times the cycle life and five times the float calendar life. It weighs about forty percent of a comparable lead-acid battery, and it is presented as a drop-in replacement. At a high discharge rate it can deliver about twice the power of lead-acid while keeping a high energy capacity.

The chemistry matters on a tower. Lithium iron phosphate is the type SARBS highlights because it reduces the risk of explosion or combustion from high impact, over-charging or a short circuit. The same product note says the battery supports an unstable partial state of charge, the charge-and-discharge pattern many off-grid and hybrid sites actually live with.

Where it sits on the site

• On the 48V DC bus, next to the rectifier and the radio load.
• Inside an outdoor cabinet, where the lower weight makes the lift and the shelf easier.
• As a replacement string when a lead-acid bank is due, without redesigning the whole power train.

What to confirm before ordering

Match the voltage and the capacity to the existing plant, check the charge settings the rectifier will apply, and plan the mechanical fit inside the cabinet or the anti-theft rack. SARBS lists this battery with its power products. For a site survey or a quotation, contact the team in Gulshan.
