Umm…there’s essentially no difference between the last pre-production cells (D Samples) and the full production cells.
If there was there would be another run of pre-production cell to confirm the performance changes, manufacturing consistency, yield percentage, etc.
Loiza en la casa!
Caguas !!!
Mooch I will send you 2 samples from this ones.
You can now sign up for in-stock email notifications for 50PL from Nkon. @Dinnye if you’re still looking for upper-end tabless cells. EVE INR21700-50PL 5000mAh - 50A
Umm…heck yea! Thank you!
DM’ing you.
Pretty sure they’re not rewraps as Reliance is a pretty big manufacturer and everyone is getting one the high power 5Ah cell bandwagon lately. We’ll find out though!
Definitely not re-warpped.
Reliance is a new upcoming High Power Cell Manufacturer.
As far as I can say they perform exceptionally well.
I guess we will hear more from them in the upcoming years.
How soon do you think we’ll be able to get our hands on the Reliance RH60s?
I wonder who will be the first to release the 6AH power cell.
11 months ago the Molicel P50B was barely available, and the P45B was still 8+$.
Wow that’s a nice deal. 3.5€ for the best cells available! I should pick some up too
I’m only running 2p, and hub motors, and a Lingyi, but when I made a BAK45D tabless pack, there was 25% more torque.
I am very interested in how tabless cells, especially the EVE 50PL, and welded with 0.3mm copper, affects the torque of an articulate Esk8 racer and very capable DIY’r.
Absolutely the thicker copper you can weld the better for keep the system cold and keeping minimum sag.
For me it’s not just about torque, but about fighting overheating issues. And getting rid of sag so that it’s still powerful when not fully charged. My 21S4P P42A pack with 0.2 nickel gets to 80C, so that’s not really working in the raceboard anymore
Will be a while until I get to build the new pack though.
Try using thicker wires and thicker busbars. The same busbar, when made with copper 0.2 or 0.3, can transfer heat to the cables and act as a cooling agent. It also has less resistance, allowing current to flow more efficiently and reducing heat. More resistance equals more heat under load, especially under heavy load.
The P42A cells are not the best choice today for high-performance or high-current loads. I’d say they’re fine up to 22A, but they still sag quite a bit.
If your problem is sag and heat, try using a tabless cell like the EVE 40PL, which is now pretty cheap probably as cheap as the P42A. For example, under a 40A load, the EVE 40PL delivers more than 4Ah, while the P42A delivers less than 3.9Ah under the same load and cannot even finish the test because it hits the temperature cut-off. The EVE 40PL, on the other hand, stays under 70°C by the end of the 40A test, likely even lower.
I’ll do the new pack with 0.3 copper and beefier conductors all around. And 5 or 6p probably. Just need to design the new chassis first and see what I can fit. And 50PL cells since they seem to be the best ones on the market right now
It will be a while before I get it done though
I wonder when any potential competitors to 50PL might be dropped?
BAK 50D
Ampace JP50
Molicel S, And X series, and the P60B.
The P50b had a short run as king, then the tabless’s dropped and voltage sagged and heated less.
The P50B is still the king for charge current (25A), consistency, cold weather performance, cycle life, abuse tolerance, and all that other stuff no one cares about.
