I’m thinking of those LiitoKala Lii-70A 32700 lifepo4 3.2v 7000mah.
They are rated 30A but I saw a test where they say they would hardly go after 20A due to heat.
I was thinking building a 14s5p pack which would make 44.8v/35Ah/100A.
The only thing bothering me is if it will be enough to sustain current draw or if I need to increase parallel. If you say 100amps is the average it might be sufficient though as that would be exactly what the pack can provide continuously. Otherwise I’ll go for 6p or more (just that they sell allready made 1s5p so simpler)
EDIT: another thing is weight… cells are around 150g each which would make a total 10.5 kg. which might be a bit heavy?
