The TSBAT12-10L-WT LFP (LiFePO4) battery is a wide temperature, 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. Typically LiFePO4 batteries should not be charged below 0C and require DC heaters to be able to charge at low temperatures but with our wide temp Aluminum anode, the battery is able to charge down to -30C without adversely affecting cycle life. 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 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.
