Power Systems Questions

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.

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).

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.

Life at 80% DoD: 2,000 cycles

Life at 50% DoD: 5,000 cycles

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.

To dispose of your used Lithium battery, you need to take it to an authorized Lithium battery Recycler / Disposal outlet in your area. Do not put it in your home domestic general or Recycle Bin 

It is important to note that the type of Lithium batteries installed in the Automotive 4WD and Recreational Vehicles is NOT likely to be the same type fitted to devices such as E-scooters, E-bikes, electric vehicles. (These are Lithium-ion, most likely Lithium and Cobalt.) The standard battery fitted to your RV/ Caravan and 4WD is almost certainly Lithium Phosphate (LiFeP04) which has a long track record of safety – this battery chemistry is inherently MUCH safer, has a longer life, and is cheaper It also has the added protection of a built in BMS which protects and shuts the battery down in the event of Short Circuit, Over charging, Low discharge, Over and under Temperature, Our batteries also meet required Australian Standards with IE62619 Certification  

The answer is Yes you can However there are a few limiting factors as well as important features of the charger to look out for. You must NOT use a lead-acid charger if it has an automatic equalisation mode, which cannot be permanently turned off. A lead-acid charger can be used if set to charge no higher than 14.6v Preferably 14.2v to 14.4v. This can be used for regular charging and then MUST be disconnected after the battery is fully charged. DO NOT leave the lead-acid charger connected to maintain or store the battery, because most will NOT maintain the proper voltage required for Lithium and ultimately only charge your Lithium battery to approx. 80% of Capacity and damage may occur to the battery and this is not covered under battery warranty. 

We recommend using a battery charger with a specific Lithium charge algorithm is the best option for maximum performance and lifespan of any lithium battery.

Having a charger that has a fixed lithium profile is good but having a charger that can customise your Lithium Charging profile is the best option as some battery manufactures require different charge voltages and being able to customise this is key. 

Lithium batteries are a great option for use while camping. Compared to a traditional Lead Acid Battery they are much lighter, approx 1/3 of the weight, they are generally a lot smaller in physical size while maintaining a larger useable capacity. Another great feature of Lithium batteries is that they charge a lot quicker than a lead acid making them more suitable for portable solar charging while off grid. 


Product Specific Questions

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. 

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

The CTEK D250S Dual only charges from a solar panel while the vehicle is turned off. For more information please click here

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

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

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.

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.

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.

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.

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.
