Why Lithium?
Lithium batteries 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

What is dual DC-DC Charging?

With the DC-DC model of the Baintech Lithium PowerTop you can charge in two ways:

  • 10A via Ciga Plug Connection or 
  • 20A Via Anderson Plug Connection for vehicle charging

How do I charge the PowerTop?
Standard Baintech 50Ah Lithium PowerTop Model is charged via a dedicated Lithium battery charger, external DC-DC, or via regulated solar charging via grey Anderson.

How much solar can I use to charge the PowerTop?
The maximum amount of solar to use with the PowerTop is 800 watts.

Is it waterproof?
The PowerTop is not waterproof. Whilst the battery is mechanically protected, the enclosure is not designed for a wet environment. Do not submerge the battery in water or expose the battery to direct water spray. Avoid exposing the battery to salty water spray and keep in a protected space.

How do I know if my battery is fully charged?
The Voltmeter will indicate the battery voltage. Use the below as an approximate guide.

  • 100% - 13.4V
  • 50% - 12.8V
  • 0% - 10V
  • How long will it run my fridge for?

This will vary greatly on your fridge type; operating amp draw and varying heat conditions. Remember, it is best practice to keep your battery topped up, by putting more in than you are drawing out.
