Power Systems Questions

  • How do I choose a battery charger?

    General rule of thumb is to calculate by multiplying 10% of your battery size. If you want to charge a 200Ah Battery : 200Ah x 10% = 20 : 20A Battery Charger.
  • What type of Lithium Do you use in your Batteries?

    All of the Baintech Lithium Batteries are constructed using the latest generation prismatic lithium iron phosphate cells and have an inbuilt Battery Management System (BMS).

  • What is an IP rating?

    IP rating stands for ingress protection rating, it deals with how much the product is protected against the ingress of water and dust. For more information please click here.
  • What is the lifespan of Baintech Lithium Batteries?

    Life at 80% DoD: 2,000 cycles

    Life at 50% DoD: 5,000 cycles

  • What is the warranty on Baintech Lithium Batteries?

    5 years

  • Lithium Battery Operating temp states max 45° – how that will go in summer when the inside temp of my car will go beyond that?

    The specs operating temp is related to the core temp of the battery/ cell not the ambient temp such as in the car temp.

    Secondly, Lithium batteries do not vent or gas in any way as they are not liquid and fully sealed cells.
    Being Prismatic cell, they are aluminium cased cell within an aluminium battery case so has dual aluminium cooling heat sinks.

Product Specific Questions

  • Why is my Baintech Volt/Volt Meter not displaying a voltage?

    When installing a Baintech Volt/Volt meter, make sure that if you are only measuring the voltage of one battery, you connect the cables to the terminal marked V1 on the back. If you connect a single battery to the V2 terminal it will not work. For more information please click here
  • Why is my CTEK D250S Dual not charging my batteries?

    The D250S has a cut out voltage set at 13.2V, so you must use the D250S Dual with a battery charged above 13.2V. For more information please click here
  • Why won’t my CTEK D250S Dual Charge from Solar Panels?

    The CTEK D250S Dual only charges from a solar panel while the vehicle is turned off. For more information please click here
  • Can I use a CTEK D250S Dual in a vehicle with a smart alternator?

    You can use a CTEK D250S Dual in a vehicle with a smart alternator, provided you have an automotive relay installed. For more information please click here
  • What is the difference between a pure sine and modified sine inverter?

    Both types of inverter will provide power to AC appliances, however Pure Sine is high quality equal to (or better than) the power in your home, Modified sine wave power is an simpler form of power and is adequate for simple electronics, but may damage more complex ones. For more information please click here

PowerTop V1-V3 Questions

  • How do I charge the Power Top when the battery is dead?

    You have to charge the Power Top through an external charger through the Grey Anderson plug. The CTEK MXS15 (CT15000/12) is the recommended charger for the Power Top. The internal charger will struggle if the Power Top battery falls below 12 volts.

  • Can I jump start my car from the Power top?

    The Power Top is not designed to jumpstart a car. The unit has a 50amp current limit inside which is not enough to jumpstart a car with. As such it should not be attempted.

  • Why does it flick between boost and float while charging?

    This is standard operation on the 2nd and 3rd model. The lights are regulated by voltage which toggles towards the end of the charge cycle. The toggling happens when the battery is almost fully charged.

  • Can I use the sockets on the front if I am charging?

    No, using the sockets at the front while charging through the 240v socket will result in the battery not charging, and draining through use. However, one can do so if you use an external charger (around 15amps) plugged into the Grey Anderson socket, or a larger solar panel (at least 150 watts or bigger) plugged into the Red Anderson socket. Either will supply enough current to sustain battery charging while using appliances.

  • What does it mean when the mains light is flashing?

    This happens when the battery is heavily discharged. There is a sequence to charging the Power Top through 240v. Make sure the wall unit is off as well as the Power Top. Once everything is plugged in and ready to go turn the wall unit on first and then turn the Power Top on.

    Do keep the PowerTop fully charged to maintain battery at optimum capacity. Repeated deep cycling (deeply discharging the battery) reduces battery life. Where practical, plug the PowerTop to the mains or other power supply to keep the battery fully charged.
