The 100ah Relion Lithium Deep cycle battery.

This is one spectacular battery.
This battery does everything better than a AGM deep cycle.
Heres a few points which make us blown away by lithium technology.

*Useable AH, due to it happily discharging to 95% of its capacity
*Insane cycle life 10-30 times even the best brand AGM deep cycle
*Weight a fraction of the weight of traditional lead acid batteries
*common case sizes , direct replacement for existing battery bank (charge system permitting)
*does not sulphate. Can be stored in low state of charge and wont harm battery
*Very Safe. Battery management system built into battery to protect against over charge and over discharge
*Unbeatable price per cycle. Due to high cycle life
*The relion brand can be charged by most Projecta 240v charger and DC to DC charger (in agm setting, we also sell all compatible chargers to suit this battery)
*Relion is one of the most trusted names in Lithium Deep cycle.
*3 year replacement warranty

To get the equivalent useable AH from AGM deepcycle your need close to 200ah and whopping 60.8 kg.

Although the AH may seem low, it can be discharged much much lower.

But its not just weight. The specs are out of this world. Approx 17 times more cycle life, if cycled 95-100% discharge vs agm at 50% discharge which is both discharged at they’re maximum recommended discharge.
