Camper Pack 1: DMT1230 + 1 x LiFos is a 68Ah deep cycle Lithium-Iron Phospate (LiFePO4) battery.
Lithium-Ion batteries offer significant advantages for those reliant on mobile power. Good quality, deep cycle lead/acid batteries can be discharged to about 50% of their rated capacity. Lithium batteries allow you to pull around 90% - meaning that they are almost twice as powerful.
Until now, Lithium was reserved only for those with massive budgets! Simply Split Charge’s LiFos battery changes things..
LiFos is a 68Ah deep cycle Lithium-Iron Phospate (LiFePO4) battery. It is equivalent to a 120Ah lead/acid battery. Multiple units can be used in parallel to provide more capacity as required.
Cyclic Life of LiFos is significantly greater with LiFos. A quality lead/acid battery will provide around 1000 cycles (to 50% depth of discharge). LiFos will cycle to over 4000 cycles at 50% depth of discharge and 2750 if taken down regularly to 90%.
Unlike many Lithium batteries, no external BMS (Battery Management System) is required as each battery has this already built in. What’s more, a Bluetooth connection and App (Apple/Android) provides a useful battery monitoring feature. Due to the onboard BMS, LiFos in many circumstances can be used as a ‘drop in replacement’ for an existing leisure battery.
Lithium technology is slightly different to Lead/Acid. Any installation must be modified if required to suit the limitations noted below:
LiFos will operate between 0 and 60°C. While the battery will provide power below 0°C, it won’t charge. In most applications in the UK this shouldn’t present a problem – If you try to charge or discharge outside the temperature limits, the BMS will shut the battery down.
A single LiFos battery will accept up to 40A charging current. Any battery charger used must have a lithium ion setting and should be fitted with a temperature sensor. If 2, 3 or 4 LiFos batteries are fitted in parallel, the max charging current can increase to 80, 120 and 160A respectively.
A single LiFos battery will provide up to 60A discharge continuously (equivalent to a 750 watt inverter). Again, if 2, 3 or 4 batteries are run in parallel, this limit increases to 120A (1500 watts), 180A (2250 watts) and 240A (3000 watts) respectively.
LiFos is not designed for engine starting or running very high current loads like bow thrusters.
Charging must be via a device that provides a temperature compensated 3 stage smart battery charging device with a Lithium Ion battery programme.
The Abso 20/40A charger with temperature sensor is ideal.
For charging from a vehicle battery, a quality DC-DC Battery Charger must be used, again with Temperature Compensation and Lithium-Ion charging programme.
For a single LiFos the 30A Abso DC-DC Charger is ideal – for 2, 3 or 4 LiFos, we suggest using the 50A unit.
Need More Power?
Up to 4x LiFos can be connected in Parallel to provide a 12V 272Ah battery bank.
The batteries must be connected using identical length battery parallel cables as shown below.
2x LiFos can be connected in series to provide a 24V 68Ah battery bank.
4x LiFos can be connected in series/parallel to provide a 24V 136Ah battery.
In 24V format the current limits for a 68Ah block are 40A/60A and 80A/120A for a 136Ah set-up.
LiFos is supplied with a 5 year warranty.
