Hello everyone, I’ve got a bit of a dilemma here. For my current (unbuilt) setup, I’ve got:
Batteries: Samsung 18650 25r —> 2 packs of 10 in series —> 5ah at 36V with 40A continuous output
Motor: 200kv 2300 (max) watt brushless (to be used in mono drive)
BMS: 40A continuous
Belt Drive: 16 tooth to 48 tooth
Wheels: 83mm
I’m debating whether I should build a second battery pack, putting me up to 10s4p. As is, do you think 10s2p is enough power to move me around? I’m relatively light at 65kg, but I’m concerned as to whether this setup is sufficient to get me up hills. I’d love some input on the issue. I can also thrown in more info if necessary. Thanks!
10s2p would not have the same power as 10s4p. 4p effectively gives double power to 80A continuous. His BMS is limited to 40A continuous, but it will still give double the power for bursts.
You should not put 2 packs of 10 for 10s2p, you should do 10 packs of 2. Otherwise, you’ll need a BMS for each pack. You should go for 4p to minimize voltage sag.
I appreciate the input and quick reply. From what I’ve seen, 10s BMS boards rated for 80A tend to be about six times the price of a generic 40A version. Do you reckon I could connect the two 40A BMS boards in parallel, having a common charging input and discharging output? It would essentially be two identical 10s2p packs with individual BMS boards wired in parallel.
Parallel do not increase the Mah, increases the C-Rating, but if you do the calculations C-Rating*(Mah2) is the same as (2C-Rating)*Mah, so thats is why we say that is doubles the range (Experts, correct me if I’m wrong, plz)
