Tycon 12V 50AH Non-Spillable LiFePO4 Sealed Lithium Battery



The TPBAT12-50-L LiFePO4 battery is a high reliability drop-in replacement for comparable Lead Acid batteries. It provides >4000 discharge cycles @ 80% discharge, about 20x what a Sealed Lead Acid battery typically provides. It also provides almost 2x usable energy storage over lead acid batteries with the same Ah rating.

The integrated battery management system (BMS) handles all charging and discharging regulation so that the battery can be charged using the same solar or grid connect chargers used for Lead Acid batteries. Along with its standard mechanical size, the integrated BMS allows the battery to be a true drop-in replacement for a similar sized Lead Acid battery.

The LiFePO4 chemistry is very stable and minimizes the risk of explosion or combustion due to impact, overcharging or short circuit. The 40% less weight and the integrated carrying handles make the battery easier to transport and install at remote sites. Up to 4 batteries can be connected in series or parallel to achieve a higher battery bank voltage (series) or more energy storage (parallel).

There are two F2 spade terminals for connecting battery cables. For long term storage it is recommended to charge to 60% charge every 6 months.
