ITEM DESCRIPTION
 
Please Note: This is supplied with m8 bolts that screw into the battery terminals.
 
High performance 24v 100ah LiFePO4 Lithium leisure battery with a BMS that supports series and parallel expansion
 
This battery is also Bluetooth enabled
 
BENEFITS OF LITHIUM OVER TRADITIONAL LEAD-ACID
- This can be charged using most standard lead-acid chargers, MPPT solar chargers and DC to DC chargers
- These provide significant gains in power density, power delivery and lifetime expectancy
- They offer thousands of charge/discharge cycles
- Light weight - These are about 40-50% lighter than a comparable lead acid battery
- Low temperature charge protection is inbuilt
- They provide 100% depth of discharge (DoD)
- The 100% DOD offers you up to double the useable Ah capacity compared with an equivalent lead-acid battery
- Higher charge acceptance rates allow shorter re-charge times
- These will recharge more quickly from a solar panel than a traditional lead-acid battery
- Maintenance free
- Does not contain any liquids
- Will not sulphate if left discharged - no risk of damage
- No power 'tail-off' - voltage remains relatively constant until almost fully discharged
- Wider temperature operating range
- Onboard Battery Management System and Bluetooth facilities that interact with Andriod and iOS apps 
- The LiFePO4 batteries are the safest type of Lithium battery as they will not overheat, and even if punctured they will not catch fire
- The cathode material in LiFePO4 batteries is not hazardous, and so poses no negative health hazards
 
IMPORTANT NOTES: 
- The Bluetooth app is available here - https://overkillsolar.com/support-downloads/
- PWM solar controllers are NOT suitable for use with these BMS equipped LiFePO4 batteries
- Your battery can be charged by 99% of all current Lead Acid battery chargers as the charge is controlled by the batteries internal BMS (Battery Management System), However, we advise to use a charger that has either an ‘AGM’ or ‘GEL’ setting, or preferably use a specific Lithium Battery charger which will use the correct profile and charging voltage
- In any fitment where charging is via a dynamo or alternator, it is strongly advised to fit a DCDC charger to control voltage. In systems that use a ‘Smart Alternator’ or where the voltage is above 15v for a 12v system or multiple’s thereafter for series banks, a DC-DC charger MUST be fitted to avoid the BMS shutting down to protect the battery.
- The App is available for all Apple and Android devices
- The App will give you visibility of your battery and its performance. The App works via Bluetooth so you need to be within 10m of the battery to access it.
