Our products

Product category: Batteries

Lithium-ion batteries or lithium batteries from Victron and TransWatt

The light alternative to lead batteries exactly when they are too heavy

  • Capacity indicator for lithium battery
A capacity indicator is supplied with each TransWatt lithium-ion battery to provide information on the battery's state of charge.

  • Lithium-ion battery monitoring
The batteries have internal monitoring, which is connected to the associated battery isolator switch via a simple control line

  • Charging of lithium-ion batteries
Lithium-ion batteries can be charged with different currents. The charging time depends on this.
We supply the battery chargers or inverters / chargers (combination units) with the necessary charging characteristics and different charging currents. With modified charging characteristics we achieve charging times of approx. 2 hours for a full charge. With a lower charging current, the charging time is correspondingly longer.

About us

Company portrait

Accusysteme TransWatt. Your partner in Soest.
You do not know us? - It's worth changing that.

Since 1980 we have been dealing with off-grid and mobile power supplies. We develop, manufacture and sell high quality devices. This is a matter of course for us.
We offer our customers professional advice on all aspects of our products. Experienced, qualified employees guarantee the right selection and combination of the necessary components for your power supply system, consisting of battery, inverter, MultiPlus, battery charger, solar system, etc. We are proud that this distinguishes us from pure Internet dealers.

We also offer the right solutions if you want to store your solar power. We will be happy to explain the subsidies for solar power self-use to you personally.
Even after the purchase we do not leave you alone, because we know:

Not everyone can or wants to install their mobile power supply themselves.

If you wish, we can provide you with additional services such as installation and commissioning of our products. So we deliver "turnkey" on request.

Electricity. At any time. At any place. That is TransWatt.
