Amps Battery Deep Cycle Lithium Ion 12V 60 Amp W/Bluetooth

Built-in Battery Management System, safety shut-down and their own bluetooth battery monitoring.

The AMPS LiFePO4 Lithium Batteries offer twice the run-time and are nearly half the weight of similar-sized lead acid batteries whilst retaining the same form factor due to an IP rated flame retardant plastic case making them a direct replacement for many AGM, Lead Acid and Gel batteries.

With a built-in Battery Management System, safety shut-down and their own bluetooth battery monitoring app the AMPS LiFePO4 batteries are a sophisticated and durable Lithium Battery that can safely be linked together in groups of up to 4 in series to produce a 48v bank or, unlimited numbers in parallel to increase amp/hour capacity and to increase charge and discharge rates. With a recommended connection of up to 4 series and 4 parallel, the AMPS battery offers the same run time as a 48V 960Ah AGM or Lead Acid battery!

Lithium Benefits
The advantages of lithium batteries are well known over conventional batteries.
Greater energy density, providing more usable power in the same space
Superior charge and discharge capabilities
Improved unit safety
Capacity and performance - Lithium batteries allow, when the BMS allows it, full use of the battery capacity,
as opposed to the 50% recommended depth of discharge of a lead acid battery. Their low internal resistance
allows much faster charge than many other battery types and very impressive rates of discharge.
Often significantly lighter and significantly smaller than their lead acid competition.
Even when being discharged to significantly greater degrees than a lead acid battery, we will still expect to
see between 10-20 times the service life of a lithium battery against a lead acid battery

They are superior on every level - everyone wants them. However installing them on vehicles etc. was not simpleand required a lot of knowledge because they have a very specific envelope for their charging and discharging curves. Failure to operate within these parameters will reduce the performance ability and life of the battery. Lithium batteries require additional care over lead acid batteries. In AMPS batteries, much of this care is solved and monitored by the BMS onboard. The BMS tries to protect the cells from allow over-voltage, over-current, short circuit damage and over/under temperature situations.
