Does anyone have any experience with the EVE 25p cells? Especially cells from Bulk Battery. I'm planning to build a 3kwh battery pack for my stealth bomber. Are they well matched? do they hold their capacity? I plan to limit my charges to 4v per cell and do 5c peaks
I dont know about 25P cells, but I know about EVE 26V. I think is a trusted brand! At our company we recovered thousands of 26V cells from trotinetes/escooters bankrupt company. All cells used preform great, as new ones! soo maybe good cells brand
We could trust EVE and soo 25P cells could be a nice option. Let's feed EVE Chinese company! They have nice development at 26V cells, soo we assume the other models would preform very well
Anyway, 25P is a 20A cell, it means it could go maximum peak of 20A demand or maybe a full discharge at some max temperature to put out 2500mAh
Best to keep at half that value current limit. maybe 10A could be a statement for long life and safety..
stealth bomber needs high current delivery, If you go for 10P configuration, means 100A limit (on safety limits)
if ebike draws 120A peak , maybe U need to go for 12P configuration..
But if you want to save cash go for a bomb battery 6P (each cell 20A x 6 = 120A)
This is the minimum parallel cells configuration for 120A peak demand..
maybe stealth bomb could go sometimes to 200A..
Be on the safe side when using high current loads!!
The best cells at market are Sony/Murata(Japan) and Molicell (both for 30-35A) :thumb:
