So I finished out by charging the battery with a 14.6v power supply until the BMS cut off, which only took a couple seconds after all that charging I did with the noco battery charger. It's doing the exact same thing. I let their support know and they are offering an exchange or refund, which...

It may have been, but I tested again after warming back up and it did the same thing. Ampere time got back to me with a sassy comment about not doing what they are asking to troubleshoot when I brought up that last vid. Waiting on a variable DC supply now to complete testing, but ordered a SOK...

OK so next question, what would be a good battery in place of this? I'm just worried about this same thing happening again. Cold weather, western PA but I have the batteries in an insulated box. Seems like SOK is one of the better options. To the regular, non-heated Ampere Time batteries do...

Yup, just watched it and that's EXACTLY what's happening. I guess we'll see what they get back with.

Thanks! I was searching youtube for reviews but none were the heated version. I must have missed this one.

found another 15a charger with a display and it's pulling in 14.5a

That's what I'm wondering. I'll try the test again when they warm up in the house, about 70f right now. The charger should help warm up the cells too.

It's a noco battery charger, put it on the lithium function. Says it should be 15a, but it doesn't show an output. Sounds like it's choochin good though.

They were just outside and air temp is about 40f, so it could be the heaters doing something weird.

That was my thought too, if the heater is kicking on or something weird. I did that test when they were still cold from the outside, trying to minimize environment variables from the field. Charging now, going to do the same test once warm to see what happens.

lol yeah, very weird thing happening here. both batteries are doing it too. I have an email back out to Ampere Time with the video, hopefully they have a recomendation that works. Currently have them on the supply charging up, but I already had them fully charged before i field deployed.

I just pulled the batteries back from the site to isolate and troubleshoot. I made a video to better show whats going on. https://photos.pinecone.fun/mo/sharing/pkvGD8o6m I'm using a 13.6v power supply with those clamps. Both batteries are doing the same thing.

Would not setting a new battery at full charge cause the BMS to reset when switching from charge to discharge?

Thanks. Wiring was tight but i'll reconnect everything and try again. Battery was anywhere between 13.4v to 13.01v and still doing it. When charging in full sun, it's pushing 13.5a, about 200w. wiring from charger to batteries is 12ga, about 6' of it. 4ga between the batteries. I have a...

This is my first go with a LiFePO4 battery system on a solar site. I have 2 other sites supporting wireless equipment for remote connectivity, so everything is outdoors. The problem I'm running into is when the system gets full sun, or falls out of sun quickly, the batteries drop all voltage...
