Usable power comparison

This demonstrates the power you can actually use to power your appliances

Appliances such as TVs, LED lights, satellite systems, heating controls, inverters etc. require stable voltage above 12 volts to operate. Lithium iron phosphate battery voltage remains stable right to the very end. Lead Acid, AGM and GEL does not!

Everything working functionally

Below here - Equipment starts to fail and turn off.

Danger - The battery is being severely damaged.

Permanent Damage - Replace battery. Unrecoverable.

Lead and AGM manufacturers quote: "At 12 volts there is a tipping point where the voltage goes from relatively constant to plumeting rapidly"

Total AMP Hour Comparison

Also, at 50% DoD the voltage will not be sufficient to run anything other than old style lights. LED lights, TVs, satellites, heating systems, power inverters, fridges and other such like appliances, cannot usually be powered below 10 volts.

Please note: if a lead acid battery is taken below 50% DoD this will severely damage the battery. This does not affect lithium iron phosphate batteries in anyway.

*Note: Lower C rates will extend the battery life. Manufacturer suggests a C/0.6 (60 AMPS) as optimal daily charge or C/1 (100 AMPS) as maximum fast charge. After 5000 cycles, there will be approximately 75-80% battery capacity remaining if charging/ discharging at C/0.6 rate (60 AMPS)

Huge weight saving - increase your payload

transporter energy weight

You only need 1 lithium to 2 - 3 lead due to their high power density.

Transporter Energy Capacity

By connecting the battery in parallel you can create a solar battery or off grid energy storage any size to suit your requirements. Battery banks can have unlimited batteries in parallel and be configured in series to 12, 24, 36 or 48 volts.
