About this product :
Victron lithium-iron-phosphate (LiFePO4 or LFP) batteries offer a high level of safety and excellent performance at a reasonable price.
Efficiency
LFP batteries are particularlyefficient in off-grid systems where you have a large battery and day-to-day only use the top 20% or so. In this situation lead-acid batteries often have an efficiency of ~50% but LFP batteries can achieve ~90%.
In grid connected storage LFP batteries can still be significantly more efficient than the lead-acid equivalent. The round trip energy efficiency (discharge from 100% to 0% and back to 100% charged) of the average lead-acid battery is 80% as opposed to 92% from an LFP battery.
Key specs & features
Light - save up to 70% weight
Energy dense - save up to 70% in space
5000 cycles to 50% DoD (depth of discharge)
3000 cycles to 70% DoD
2500 cycles to 80% DoD
-20øC to +50øC operating temperature (charge current reduced at low temperatures)
IP 54
13,6V float voltage
14V-15V charge voltage (<14,5V recommended)
Victron lithium-iron-phosphate (LiFePO4 or LFP) batteries are the safest type of mainstream li-ion batteries
BMS - With cell balancing and interface to connect to a Victron BMS
For heavy duty applications and parallel/series connection.
These batteries have integrated Cell Balancing, Temperature and Voltage control (BTV). Up to ten batteries can be paralleled and up to four batteries can be series connected (BTV?s are simply daisy-chained) so that a 48V battery bank of up to 2000Ah can be assembled. The daisy-chained BTV?s must be connected to a Victron battery management system (BMS).
