Product Description         
1.- Series: It is not recommend to connect more than 4 batteries in series .
- Parallel: It is not recommend to connect more than 4 batteries in parallel.
- DO NOT string batteries in series and parallel at same time. Doing so can cause catastroph-ic failure.

2.The following diagram is a reference on how to connect batteries in series and parallel using 12V100Ah battery. Before
connecting , each battery must be independtly fully charged.
- Series Connecting Total voltage and capacity: 48V 100Ah ;
- Parallel Connecting Total voltage and capacity : 12V 400Ah;

3. *Before making any connections, make sure to charge each battery up to 14.6V with a proper lithium charger. ALL BATTERIES SHOULD BE AT THE SAME STATE OF CHARGE PRIOR TO CONNECTING, otherwise you will encounter balance issues within your system.

*All cables and connections must be able to accommodate the high currents that can be delivered by the battery. Appropriate fuses and circuit breakers are highly recommended to protect downstream componentsfrom currentspikes and short circuits.

*In parallel battery banks , the cables between each battery should be of equal length to ensure that all batteries in the system can work equally together.

*To string multiple batteries in parallel,first connect the positive terminals of batteries to each other. Then do the same with the negative terminals . Finally, connect the positive and negative terminals of the first battery to the system. This type of arrangement is used to increase the overall battery capacity while keeping the voltage the same.

Below are the answers to the questions that you may like to ask for


Can I charge the battery from the mains?

Short answer is yes but it will require a hybrid inverter. This would mean you could charge the battery at a cheap night rate from the grid as well as charging the battery from the solar PV.

Can I have an Uninterrupted supply (UPS) if there is a powercut?

Yes but would need to be wired to a dedicated circuit within the house, for example the upstairs sockets and downstairs lighting, this would then provide you with emergency power in the event of you losing the mains.

What’s the best location for batteries?

They work best in a room that doesn’t get too hot – Ideally they would go in a garage but they can go in a loft or any other room but the warmer they get the less efficient they become. The operating temperature ranges from -10 to 50 degrees but will see efficiency drops below 0 and above 40 degrees

Are Batteries safe?

Batteries are no more unsafe than any other electrical installation, as with anything there are risks but these are very small and should be a great consideration.

Can I add more batteries at a later date?

Yes, this battery can be in 4S and 4 Parallels, maximum reach 51.2V 400Ah for the model of 12V100Ah. 

How long do they last?

This is actually determined by the number of cycles the battery goes through, this means a full charge and discharge. On average a battery will last around 10 years and all batteries have at least a 5 year warranty and most can be extended to 10-years.

What’s the difference between Capacity and useable capacity?

Most batteries will have a capacity and a useable capacity – this can be confusing but in basic terms batteries should never been fully discharged and as such the useable capacity takes this into account.
