Yes,but they where sold as premium A Grade

My Basen grade A cells are dropping from 3,5v to 2,7v when applying a 150a current in a 4s pack config. Emily talked with the engineers and say it’s too much current. It’s just one cell doing this. I bought almost a thousand cells with Basen and this is the warranty… total scam.

This is the third BMS wich only show 0% SOC. All :JDB SP04S034-200A When i use the admin app to configure settings, i can change :Cell 100% Cap. Voltage to another value and right SOC % shows again. After a while it jumps to 0 % again. On my first encounter I discovvered when unconnecting a...

Anyone did see read the warranty ? It says 10yr warranty. Nothing more nothing less. With this products price you expect some warranty about remaining capacity after a few years.. they do not so that for the most obvious reason...

After topcharge i made a 2p8s 24v pack. Test some testloads on it before my custommer placed it in his boat. When charging the bank with 24v120a two cells climbed to maximum voltage (3,65v)while the rest stayed at 3,3v. Never have seen this before, i needed a grade cells dor this custommer...

And, how did it go ?

If your'e a technician yes, but then you wouldnt buy a pack there anyways.

Final bid was 600usd from Basen. Thats 3920-600=3320=138usd p.cell for old stock cell b grade even c grade because 2 cells already died. My custommer is not happy..

Yes, 280K

your battery id completly discharched and is in protective mode. Charge it up with a (normal) or special lithium charger , after 10 minutes your battery must be discovarble with the app. If not, another bad product from Basen Shenzen.

You have a problem then with a sealed aftermarketbox from China..

Yes, but they sold me b-grade cells for a long time, no problem with that because they make great solar batteries. But after buying a few so called A+ I'm done with them.

Can you do a discharge test at 1c, these B grade cells will perform terrible.

Basen send me LF280N from 02-2021 where i was promised LF280K with eve report to prove they where A+ grade. Never got the report. Scam compagny.
