12V 50Ah Baintech Lithium Powertop provide more usable capacity than lead acid batteries. Deep discharging does not affect the life of a lithium battery the way it does with lead acid batteries. You can use the battery longer before needing to recharge, without damage to the battery.

Cost Effective Over Life Cycle
When considering the usable capacity and lifespan of lithium batteries, they work out cheaper than lead acid. When you add the cost and inconvenience of refitting new lead-based batteries every few years the total cost of ownership over the long term is far better with lithium batteries.

Longer life
Lithium batteries are rated for 2,000 – 5,000 cycles and much more if used carefully, giving you several times the life expectancy of standard lead acid batteries

Lithium batteries allow you to pull far more amps out of the same size battery systems

Lithium batteries are less than half the weight of the equivalent lead acid battery.

Fast recharge
Lithium batteries charge more efficiently, and don’t require as many stages during charging. Therefore, they will charge faster, and hold more of the energy from solar panels and other charging device
