Thanks for the report. I am thinking and most likely will by buying the 24v 100ah ampere time battery from Amazon for $998 (thereabouts) after your report and what I've read on amazon's review. I was going to be the 24v 100ah battery from Big Batteries but they want $1600 and weighs 200 pounds. The ampere times battery only ways 47 pounds.Although not OP, I have been running this battery for 2 weeks. This battery along with a 3k inverter runs everything but the AC. Microwave is 1000 watts, Instant Pot is also 1000 watts. It does not mind the Instant Pot but I won’t be running the microwave for anything other than a quick warm up. Residential fridge pulls about 100 watts when running and it’s stays plugged in during the week while we are not there. Now the Keurig taxed it for about 120amps for a good 3 minutes while warming up the water and the BMS did not disconnect. The vacuum took it over 100 as well but i forgot to write the numbers down. I think its rated for 280amps for a couple seconds but i thought for sure it would kick off after that test. I’ll let someone way more knowledgeable on BMS to comment on good or bad.
The 100a is quite restrictive but not a deal breaker for me. $1169 shipped and it amazingly arrived in just a couple days about 70% charged. They were offering a 10% coupon on Amazon.
I’m in NW Ohio and the sun is quite low these days. I ran the heat all night this past weekend while up on Lake Erie. Along with a couple hours of TV, misc. lights and charging 2 iPhones, 2 watches and an iPad. Also the water pump and anything else we wanted. I wanted this test to be just like home and not worry about our usage.
Woke up and the Victron 100/50 said we ran through 78ah’s. There is 480w of solar up on the roof and with a nice sunny 60 degree day the battery was topped off by 1530. I have a portable 100w panel coming that I’m going to add as a supplemental ground mount to catch more of the morning sun. I think i saw a peak of 25amps going in the battery. At 0815 the charge controller showed parity between solar input and usage. So that puts it at about an average of 11-12ah recharge rate. Hopefully the addition of the portable 100 watts will shave off a bit more time.
So using less than 40% of the rated capacity i don’t think is too shabby. This battery replaced 420ah of 6v golf cart batteries. Close enough to an AH even trade and I’m almost done staring at the damn Victron Bluetooth app lol.
So if this thing keeps up this performance up I’ll buy another one in the spring and take that continuous power to 200amps.
And just a quick background. I am just a guy with some solar panels on his RV and a battery. I have no background in electrical engineering. I still google how to do the conversion calculations and all the other things required to pull this off.
Hope this finds itself useful to anyone interested in these batteries.
I totally agree. With a 100a bms you have to really careful. When discharging to set up my aili gauge, I didn't do the math and fried the 100a BMS. Spend the $100 and get a 200a BMS! Thoughts?"much cheaper" is usually a sign of shenanigans.
100A bms on a 12V is very restrictive.
I really liked my Ampere Time 200a battery, but when setting up my Aili gauge I over discharged the BMS and it never recovered. With a 100a BMS you have to do the math. Max 1000 watts? I have no idea what the max watt discharge rate is for a 100a? I returned my battery. They should be more clear what the max watt draw on a 100a BMS is! HELP!

This battery is rated to discharge at 100 amps. I discharge my Ampere Times 100a on the average 20 ampers for 3 hours every night between 6 pm and 9 pm when the Utility kicks in and then the utility charges the battery at 9 amps throughout the night.
BMF is working just fine. a couple of weeks ago, before I relocated the battery, it reached 130 F and disconnected itself from the controller. This battery at least for me is working as advertised.
Right. And the BMS should disconnect the load... temporarily. It did disconnect the load... permanently. He said that it "never recovered". That is the problem.It sounds like he exceeded the 100 amp limit.
Just to clarify, the BMS built into the battery is fine and not tripping. What is tripping is the 2424lv controller/inverter when you load it enough to draw 35A from the batteries? Sounds like it could be going into low voltage cutoff. If that is the case, you either have an excessive amount of resistance in line between the batteries and the 2424lv (too small gauge of wiring, poor connections, etc.) or the low voltage cutoff in the 2424lv is misconfigured. But this is off-topic and you should start a new topic if you would like help debugging.I have never discharged it greater than 40 amps so have never reached the high amperage cutoff point to turn off my 2424lv controller/inverter.
...
The issue I have is that my controller always shuts totally off whenever my battery discharge goes over 35 amps, but auto restarts after 40 seconds. but if I don't cut some load in the house, it will shut off again or the Grid will take over and supply the power to the house.
Could someone elaborate on this? I read that besides being the same SoC, and Ah, that they should be from the same manufacturer (including relabeled brands). Obviously CHINS and Battleborn are separate and have different battery cell structure and BMS.Should work fine. Just charge all batteries to 100% before connecting them.
I already contacted Ampere Time about warranty documentation. However, before I purchased the batteries, Ampere Time gave me the contact information for their California offices that deals with U.S. warranty issues. The offices are in Hawthorne and Compton, California. They deal with the customers having issues and send replacement batteries if needed. No word on who pays for returns.
The one battery that shut down for low temp charging is still dead showing 0 volts. I am going to reactivate the BMS tomorrow after climatizing with one of my 12V AGM batteries. I will update on how it goes.
I can't find it after a year. I will have to do some searching. If it is service related, just contact them at:Could you please share that contact information for their California offices? Please private message me if you don't want to post it openly. I have these batteries on a sailboat. Thank you
