Well i'm a dumb ass went through the wiring on the bms found i must have unplugged the current sense wires at some time. Reconnected back to the bms and is now working great now.

Thanks i read those articles last night. Great information. The problem i have found in the last 2 days of sourcing information on lifepo4 batteries and a battery management systems. There is a lot of miss information out there. Whether it is from a wrong language translation or someone that...

Well I just received my 8 new 3.2 280 ah batteries from Amy. I have one cell that has the sides at the top slightly sucked inwards with a 3/4” round bubble just slightly sticking up. Then the screws they supplied are two long even with 2 bus bars attached. Waiting to see what Amy says. Other...

I like the Chargery bms8t 300 amp bms with the 2 relays. I like this BMS because all the loads go through the relays not threw the BMS. The BMS senses the load but controls them through the relays which means no large current going through the BMS which in turns means no heat or less heat in the...

I just want to say Xuba stands behind there batteries. Amy is shipping me 2 - 3.2v 280ah cells. The cell voltage was jumping at the last minute. Gave Amy my data logs from my bms to prove what was happening. She has the data to support my claim. Thanks Xuba

The batteries look good. 3.28 -3.29 v Tomorrow I will charge them up and do a capacity test to see how they do. I’m sure they will pass with no problems.

thanks but TheGriz has purchased the relays.

Good morning I received my cells last night. 5 cells are perfect condition. 3 cells have a 3/4 round hard bulge on the top. Contacted Amy she said shipping caused the problem. I look at her original pictures she sent and the bulges were there before shipping. Not sure what to do. Going to...

I don't know about that. I'm going to use the same batteries in my motorhome. Just make sure they are fastened down. I'm waiting for the batteries to ship from Xuba. good luck

thanks for the reply

Problem is most people don't understand what the full function of what a BMS does. They are only seeing the down steam of the bms not the charging source side. No body has talked about what happens when the bms shuts down the battery pack. What can occur when your charging and the bms suddenly...

i have decided to change from a Chargery bms8t 300a to Electrodacus sbms0 bms. I will be putting the chargery bms's up for sale. I have 2 chargery bms8t 300a bms going to put up for sale for what they cost me. one is brand new and the other has maybe 30 days of operating. The used Bms will be...

thanks for the info.

I'm just understanding myself. From what i have read about solar charge controllers, mfg say you must have a battery connected to the charge controller before turning on the charge controller or you can damage the charge controller. No warranty if you don't before turning on charge controller...

Sorry everything is sold.

Try Craig the moderator. If I remember I think he was selling them. But not 100%

Well it’s nice to know there is no danger but the question now is this is a blemish battery not a perfect or grade a battery. The plug as she calls it should have been filed down flush with the top. So it would not be showing. any battery dealer in North America sells blemished batteries at a...

I ordered 2 Chargery Bms8t 300a bms from Jason at Chargery back in late February 2020. They arrived in late March 2020. One Bms I’ve used for a month, the second bms has never been used. The slightly used Chargery Bms8t 300a comes with a 300a shunt, 2-300amp relays and delay board asking $ 125...

I had replied with a price but I see it’s not there. how does $80 usd plus shipping for both. I paid $62 usd ea. I can also give you the delay board if you want included. That was $15 usd.

Were the batteries shipped directly to your home. It's funny that i found this topic on lifepo4 batteries in this forum. Was just going to order battle born batteries today and came across this great info. I had thought about buying from Alibaba but was afraid the duty and taxes would put the...

I wish it went down it’s pretty hard

I have found out the hard way that when the Chargery bms shuts down because of a low cell voltage event. It only shuts down the discharge relay only. It does not shut down the charge relay, so when the bms shuts the battery pack down because one cell discharging down to 2.5v ( as the bms is...

Sorry i'm going to ask a probably dumb question. I have purchased 8 - 3.2v 280ah lifepo4 cells as 2 seperate banks recommended from this forum from China. I'm trying to understand the setup for using a Chargery bms8t 300a BMS. Can my lifepo4 battery power the bms as internal and do i have to use...

What BMS is everyone using with these 12v 280ah batteries. I was hoping to find a BMS with low temp shutdown. thanks

Glad you checked before the cells shipped.

No i have not bought my Chargery bms8t 300a yet. waiting for Jason to get back to me. One battery pack is for my 12v fridge in my jeep and the other pack with go into our motorhome. i'm won't be running any big loads. max would be 150 amps every once in a while. Will be charging both packs from...

yes i still do have both Bms's. email me craig1mckenzie@gmail.com Thanks Craig

to update my sale of Chargery bms8t 300amp bms's. I have sold the relays. I have for sale: one used 30 days Chargery bms8t 300amp bms with a 300a shunt $75.oo usd + shipping. Works perfectly, used maybe 30 days only used for testing new lithium Battery pack. one new Chargery bms8t 300amp bms...
