To give you a bit more context, here’s what I’m trying to decide between:
So I’m deciding now between building a 8s2p battery with Samsung 30Q cells:
BMS (they provide 3.6v BMS too)
Or just buying a couple of Hobby King Lipos (series of parallel) and saving myself some time. From what I see they cost roughly the same.
The main difference I see between the two is the c-rate or the max currents. The Samsung cells offer 15A output which intuitively would double in parallel while most lipos offer (5AH*25c) 125A! Ok so a huge difference, I’d need a number of parallel cells to keep up. But maybe 125A is overkill, I’m really only interested in finding the minimum output current required for my use case.
Also, “Burst” output is often mentioned. Is this the output while I’m going at full throttle or is it usually only achieved when going up hills or accelerating from a standstill? There is no mention of “burst” or anything like that on the samsung cells so I don’t really know how they’ll handle on an eSkate.
And finally: If I made it well, and without mistakes, is £75 a good deal for the BMS/Cell combo? 6000Mah + long lasting cells, only downside seems to be that it’s limited to 30A possibly.
If you need to ask me a question (about my build plan) before you can answer mine feel free. I’ve only taken an interest in eSkates this weekend so I’m a bit of a noob and my mind is numb from research.
Thank you to Peter Griffin and the Aku Aku mask guy and everyone else who’s in pretty much in every thread.
PS I searched already
Maybe won’t be able to reply to everything tonight.
