To top ballance I hook up bms and charge with a 20 amp watte charger for lithium and then top ballace with a dc 10amp power supply box. Then do capacity test after done charge back up with 20 amp watte charger.What charger do you use to charge your cells initially and back to peak following the capacity test?
Not a bad price.I am considering ordering the 304's. 16 shipped to my door is about $2400. Seems like a good price at this point. The "Michael" prices from February are long gone I think. Anyone else get some from her?
I'm assuming your talking about the one that you can adjust the voltage on that is used for top balancing. If so yes you can. I would have a bms installed if charging at 14.6vWhile I know it would take longer, could I get by using the 10 amp power supply to do all of the charging?
I prefer JBD. The 100 and 120a are the most popular, but I currently use two of the 150a models that are the size of a loaf of bread.
The new design is smaller. It's also easier to hook up with the threaded ports. The 100 and 150 look the same. I have only got the 100 4s and 150 4s.. both are the same size. This is the 150 attached to batteryI prefer JBD. The 100 and 120a are the most popular, but I currently use two of the 150a models that are the size of a loaf of bread.
A few US based sellers carry JBD and Daly, but most of them don't have a decent selection. It would be cool if you had a 12, 24, 36, and 48v option.
Absolutely do consider a BMS essential and would only do a 4 cell initial parallel charge if I needed to wait for a BMS. Thank you for your time and information.I'm assuming your talking about the one that you can adjust the voltage on that is used for top balancing. If so yes you can.

How much time was required from your order to pick up?Just opened and checked all 8 boxes of 2 and look awesome. 2 hour drive home now. To avoid credit card fee and or dirtbag paypoop and your picking up in Houston tell Amy pickup with cash. Save 68 dollar paypoop fee, joe.
The Chinese fall holiday I think started today. So we probably won't hear from Amy for a week or so. I'm pretty sure she'll email you an invoice once she's back to work.@Amy Zheng
Regarding BMSes,
I think most people are buying cells in multiples of 4, therefor I suggest you import 1 or 2 models for each bank variant (4S, 8S, 16S).
In my opinion, you should concentrate on models capable of 0.5C of you average battery size.
Assuming you sell mostly 280AH-304AH you should import BMS in the 140A-152A range.
I think new smaller and enclosed model of JBD Smart BMS 150A with Bluetooth (https://www.aliexpress.com/item/1005002338673024.html?) will be optimal.
Also newer 200A with built-in balancer (https://www.aliexpress.com/item/1005002958135242.html) and handy cable leads looks good.
Regarding cells purchase,
I am looking at http://www.powerwholesale.net/usa-d...4v-48v-320ah-storage-battery-bank-p-3882.html. The description is confusing, are EVE 304 or CATL 304?
Also the website (http://www.powerwholesale.net) won't allow placing orders and HTTPS (encryption) is not enabled.
How exactly the transaction is done after the details are discussed over email? Where the payment goes? Do you provide PayPal invoice or similar?
Thanks.
Thank you, Its okay I can work any time at home. Just response maybe delayed few hours during the holidays, any questions welcome to contact me
Excuse my ignorance but what are EVE cells and what are CATL cells? What are the differences?@Amy Zheng

EVE and CATL are cells manufacturers.Excuse my ignorance but what are EVE cells and what are CATL cells? What are the differences?
