NOMINAL VOLTAGE: 3.2Vwhat's the spec sheet say about charge completion? for lishen, (iirc) when current drops to 8 amps @ 3.65v the charge is complete.
i was able to pump ~9.75a in with my little 10a supply. I used thick (10 awg) wire with ring terminals for connection both to supply and battery. You can probably forgo the overkill 10awg but ring terminals are almost necessary.
I built a new charge lead with some ring terms on it and the charger immediately started pushing 10 amps instead of 8.2.
Nice. Didn't think it would make much difference at this low voltage.
What do you have feeding them power?Up to 3.39v on the parallel pack.
I ended up attaching two of these: https://www.amazon.com/dp/B08LPVWX74?psc=1&ref=ppx_yo2_dt_b_product_details
One on each end of the bus bars. Ive been really happy with Drok gadgets. These happily push 12 amps each at 3.6v
How curved? What's your rig? I'd bet someone hear has done it...It's a curved top so I might have to go with two flex panels
