How to size battery cable for 48v systems?
The parallel connections share the amperage. Let''s say you have 2 batteries in parallel. Then each battery will handle 1/2 of the amperage. If you had 3 in parallel then each would handle 1/3 of the amperage. So one would think that for the parallel connections you could use smaller wire appropriate for 1/2 or 1/3 the amps.

If I build a pack of 6 18650 batteries in parallel which are 3500 mAh each, that would make the pack 21 Ah in total. Yes. Then I take those 6 and make 13 more packs and wire those in series so I have a total of 78 batteries making 48v (3.7v * 13). This would make a 48v 21Ah battery. Yes. But, you meant "12 more" and so "13 total".

6 FAQs about [48v battery pack parallel effect]
Does number of cells in parallel affect pack voltage under load?
The number of cells in parallel will effect the pack voltage under load, but that is a different calculation. The graduated cells plotted versus series and parallel give the total pack size in kWh. So, this chart gives you the energy (kWh) and the absolute maximum and minimum pack voltage. The final two charts give:
Should a battery pack be a parallel battery pack?
Having Battery Packs in Parallel are no problem until you start to get past 4 packs and things become a tad more complex. Having a minimal difference between packs is Best ! 271AH & 280AH is fine, but 150AH difference is NOT, that creates other issues. The closer the better. NEVER EVER MIX CELLS !
What is the difference between series and parallel batteries?
Both of these designs have strengths and weaknesses. Hence both have places where they are optimal. Parallel and then series will be the lowest cost, but least flexible. Series and then parallel gives flexibility and redundancy and hence is often found in large battery packs.
What's the difference between a 48V pack and a 12V pack?
Ummm, colour me confused. 48V Pack requires 16 LFP Cells @ 3.2V, with a 16S BMS. 12V required 4 LFP cells in a 4S Config with a 4S BMS. It is NOT recommended to put 12V packs in Series, 1 12V pack cuts off and the other BMS take the Voltage Hit and goes POOFDA !
What determines the operating voltage of a battery pack?
The operating voltage of the pack is fundamentally determined by the cell chemistry and the number of cells joined in series. The ampere-hour capacity of the pack is determined by the capacity of a cell and the number of cells in parallel. This is the approach used in most passenger car electric vehicles and smaller battery pack designs.
How many 48v battery banks should I add?
The plan is to add 2 additional 48V battery banks in parallel over the remainder of the year. I'm almost ready to add the 2nd bank which will raise the system to ~28kwh in total.
