I use keeppower 5000mah. There is a gentlmen here that sells them in pairs for a good price. Look up doingoutdoors.com in the thread search. Should pull it up. Maybe someone here can lead you in the right direction to contact him. I also bought some from Mountain Electronics while they were on sale. Shokli brand I believe. Great cells. I also have some of the EBL’s and I know they get a bad reviews but I tested them in my lii-500 and got 4700mah to 4800mah and they have never let me down. I bought them when I first got into my lighting hobby. May not have bought them with the info I have read here but other than hearsay they have been great. Good luck, there are alot of good cells out there.
mAh is not the problem on cheap EBL cells its missing internal safety and poor internal resistance
do a discharge at 10A and you see how bad they break in
I’m not doubting there quality is not as good as other better known brands. Just saying before I knew better I bought some and for what I use them for they work ok. No, they don’t produce the output as others but they have all worked without issue. I don’t necessarily recomend them but they will work. Alot of people such as yourself just dismiss them but anyone who uses them on a regular basis could disagree with some of the negative remarks other say about them. I really think they are OK for lights or devices that do not require high output.
