Hi,
I'm a bit confused about the datasheet of the Victon Smart Lithium batteries.
It says:
Our LFP batteries have integrated cell balancing and cell monitoring. Up to 5 batteries can be paralleled and up to four 12V batteries or two 24V batteries can be series connected, so that a 48V battery bank of up to 1500Ah can be assembled. The cell balancing/monitoring cables can be daisy-chained and must be connected to a Battery Management System (BMS).
I understand the limit 4 or 2 in series for max 48V.
But why the limit of 5 in parallel?
What is the maximum of batteries connected together in a System (series and parallel)?
The example in the datasheet of 48V and 1500Ah would be a set of 20 batteries 12,8V/300Ah.
4 in series and that 5 times in parallel.
Total energy of 76,8kWh.
No matter how I connect the batteries to get 12/24/48V the BMS wires are always all in series.
So why I can't connect more than 5 in parallel?
A customer needs a 24V system with around 25kWh usable so around 30kWh nominal.
The easiest would be to use 6 of the 25,6V/200Ah (5120Wh) in parallel.
A colleague told me the limit is 5 (no matter how they are connected) because of the number of cells the BMS can handle.
