Its leak-proof construction also guarantees no messy spills or hazardous leaks.
All our battery packs at Outbax, including this VoltX 300-amp-hour lithium battery, are comprised of prismatic cells and are backed with LiFePO4's signature built-in BMS. They are also tested to deliver 100% real capacity and are suitable for parallel and series wiring of up to 6 battery packs.
IMPORTANT: While our LiFePO4 batteries are top-notch & can be wired with other batteries of their kind, it is not advisable to connect any LiFePO4 batteries in parallel or series. This poses several risks and should only be done in emergencies. If you must wire batteries together, make sure you are familiar with the correct procedure or seek help from a professional if needed.
Suggestions From the Outbax Team
- Batteries connected in series should have the same amp-hour rating, while batteries in a parallel bank should have the same voltage rating.
- As much as possible, only connect batteries in series or parallel during emergencies.
- It's better to go for batteries with higher voltage when running high-power electrical appliances instead of wiring two battery packs together.
- We have available batteries with larger discharge parameters for fast charge/discharge requirements.
- Our batteries are also available in 200Ah and 300Ah for larger capacity demands.
