Hallo, I need an 16s 100A bms for lifepo4. When do you expect to have them in stock again?
Greetz, Victor Schyns
I also am in dire need of a 16S Lifepo4 BMS for my Sab 60280’s and would also like to know when supplies are in.
Yes, I also need a 16s 100A bms for my LiFePo4 pack. I am interested in knowing when they are in stock. Thank you.
I am putting together a small 12 v 280 ah system and am looking at several bms products. Your product is highly recommended but you are out of stock. While looking at various systems I noticed that JBD has a 150 A 4s 12v BMS. Are you going to be carrying that product and , if not why not?
No time to worry about it.
Would you guys stock a higher amp 48v/16s bms? Let say like 150a to 200a
I am assembling the same, wondering what you ended up with as a BMS?
That happens a lot when Will Prowse recommends stuff. Lol! A nice problem to have.
Purchased recently , my question is if I have a bad cell and bypassed now only 13 cell ev batt pk , if I buy a 16 S can 3 be not connected , or what can I do to trick it ? Thank you
I just purchased my batteries from China. It’ll be awhile… probably at least 30 days. This is for my power wheelchair battery pack build. What do you expect the turn around to be for my 8S 24v 100A BMS to be?
I am looking for an 18S programmable BMS for 18650 (older Tesla battery packs). Something you carry?
I am in need of 16s 48 volt smart bms 200a. Will you carry them?
Building A 16s 90a 48 volt lifepo pack for a golf cart. Do you have a jbd 16s 150 or 200a bms? Can you order it ?
Are you guy going to make a 12v bms 250amp
