Since Voltium Energy® does not sell products direct to end consumers we have our own network of dealers. Each dealership has their own field of expertise and will provide you with the right advice. Voltium Energy® dealers are happy to help you with your questions, so you will get the optimal solution for your application.
Go to our store locator to find your nearest dealer or online shop.
Official Voltium Energy® dealers represent the Voltium Energy® brand and its high-end products in the best possible way their customers. A strong brand can only florish with the help of strong partners who embody our values and, above all, our philosophy when helping consumers directly.
We are always happy to add new dealers to our exclusive dealership network. The first step is to submit your application via the registration form. After we have assessed your application, we will get in touch as soon as possible!
We recommend using a charger designed for charging LiFePO4 batteries. The lithium charger must use a constant current (CC) and constant voltage (CV). The constant current depends on the capacity (Ah) of the lithium battery (0.2C to 0.5C is recommended). The constant voltage when charging a 12.8V battery should be 14.6V.
As an alternative, a standard lead-acid battery charger with a constant voltage can be used to charge Voltium Energy LiFePO4 batteries, provided that the following standards are met. Failure to do so may result in damage to the battery when using such a charger.
- The charger must not have an equalisation setting.
- A maximum charging voltage of 14.6V (12.8V battery) or 29.2V (25.6V battery)
- A recommended float-charging voltage of 13.8V (12.8V battery) or 27.6V (25,6V battery)
- Some smart or multi-stage lead-acid battery chargers have an OCV (Open Circuit Voltage) function. This function will cause the charger to not charge LiFePO4 batteries that have been discharged too far.

In principle, only batteries of the same type and model can be connected in parallel or serially. So,
you should only use LiFePO4 batteries. Never connect the battery directly to a lead-acid battery,
because the difference in charging/discharging properties will inevitably cause problems.
For combined use with a lead-start battery, it is recommended to use a separation relay. This
allows optimal charging of the batteries via the vehicle’s dynamo, without direct connection
between lead and lithium batteries.
All Voltium Energy LiFePO4 batteries can be used in parallel or in serial connection. All models
support the use of 4 batteries in parallel or in series, without requiring additional engineering.
The VE-SPBT serie cannot be installed in a combination of parallel and serial connection.
The VE-SPBTC serie can installed in combination of parallel and serial connection by using a Comminucation Box (COMBOX). important is that the batteries must be from the same capacity.
Yes, we recommend using batteries from the same batch for connection in series or in parallel.
Yes, temperature can have a major impact on the performance of a LiFePO4 battery. The chart
below shows a typical ‘temperature vs. capacity curve’ for lithium at a discharge rate of 0.5C.
This alarm shows up because of the following reasons.
1. The battery connected to a inveter what is to big for the selected battery. When connecting the battery to the inverter, the inverter give a high inrush current to the battery and the BMS go in protection mode ”short circuit”
2. The battery connected to a application/device what ask to high peak discharge current of the battery. The BMS will go in protection mode ”short circuit
3. The postive and negative pole are short circuit. The battery wil go in protection mode ”short cercuit”
To solve the alarm ”short circuit” wait for 30 seconds and the protection will be solved automatically. When the alarm stay’s in protection mode, try a charger with the function >0V start-up. Our range VE-SC chargers all have this function.
The SOC% in APP of the battery can deviates because of the following reasons.
- The Voltium Energy battery has been stocked for more than 2-3 weeks without receiving a charge/discharge.
- The Voltium Energy battery didn’t get a full cycle charge/discharge.
To solve this you can charge 100% – discharge 100% -charge 100% the battery. The internal shunt wil calculate the accurate SOC% of the battery again.
The capacity in APP shows a lower capacity because of the following reasons.
- The Voltium Battery never get a 100% full cycle (full charge – full discharge – full charge).
- The Voltium Energy battery have capacity loss because of bad maintenance or because of aging.
To solve problem (1) you have to give the battery a full charge-discharge cycle for 2-3 times.
