PowerTex Batteries 36V 50Ah LiFePO4 Lithium Iron Phosphate Battery - PTL3650
Safety is a primary feature of PowerTex LiFePO4 Lithium Iron Phosphate Batteries, as they come equipped with a built-in BMS (Battery Management System). This system safeguards the battery against common causes of failure, such as overcharge, deep discharge, overloading, and overheating. By regulating the power output, it protects the lithium cells, the equipment, and the user.
Cost-effectiveness is another advantage of our Drop-In LFP Lithium Iron Phosphate Batteries. They boast a lifespan 10 times longer than average sealed lead acid batteries and can undergo repeated charging and discharging. With exceptional longevity and a low cost per cycle, our LFP batteries end up being more economical for users compared to SLA batteries over time.
In terms of weight, our LiFePO4 battery is significantly lighter, weighing only a third of traditional Lead Acid batteries. This characteristic makes it the ideal choice for various applications, such as RVs, marine use, trolling motors, backup and off-grid systems, solar and wind power setups, golf carts, and more.
Efficiency is a strong suit of the Lithium Iron Phosphate battery, with its flat discharge curve maintaining above 12V for up to 90% of its capacity usage. This results in significantly extended run-time compared to Lead Acid batteries, which typically only utilize around 50% of their capacity.
We have full confidence in the quality of our products and, to demonstrate that, we perform a 100% pre-delivery inspection and offer a 3-year warranty. This ensures peace of mind for our customers.
For optimal charging, we highly recommend using a LiFePO4 charger, as SLA chargers may not reach the optimal charging voltage of 43.2V-43.8V for LiFePO4 batteries. Insufficient charging can lead to decreased performance and prevent the LFP battery from reaching its full capacity.
