I think it depends on where you get them. The ones I’ve used were pretty bad. They were from EBay. I made a step down from a 16.6v lithium ion battery (pay no attention to the label I changed out the BMS) from a patient ventilator to 12 volts using a BEC made for RC vehicles. It’s dual output so...

I built an ADSB tracker using an RPI, SDR receiver, el cheapo solar charge controller, cigarette lighter USB adapter, a 5 ah LiPo battery and charging it with a Renogy 5 watt panel. If I remember correctly, it would draw around 3-400 mah. That was the RPI and an SDR receiver plugged into one of...

Connected using my new upgraded 14400 bps modem. Upgraded from a 2400 it was like Lightning! Ah the good ol days. Hours spent learning Dos 3.0, Xtree Pro and Xtree Gold! All of this on my 8088 with a 40mb hard drive and 640k of ram. It was a new world. Usenet newsgroups, BBS’ a full listing in...

Just to add to this, I purchased a radio from a Chinese manufacturer. The radio had a lot of problems and the software to program it was terrible. I gave an honest review stating all of the problems I had encountered. I received a rather colorful response from the Chinese seller asking me to...

I couldn’t resist this opportunity regarding RV Pugs.

Here’s one for about 55.00 dollars. I’ve bought several items from them over the years and most of the time they get it right. The language barrier tends to distort things. I recently bought a 3000 watt version from them and it seems to work fine. Don’t forget to derate it. If it says 3000, that...

Hello again all, Some might have seen my rants about my issue with the AIMS battery I bought last year. Its Only about 6 months old and it started to give me problems late last year. Last week it died completely. After several phone messages and an email asking for support without any response...

Had a similar problem with my battery. Different brand but was a failed BMS. I replaced the BMS and now it’s fine.

I’m curious where you found a 2500 amp inverter/charger?

That’s 2500 WATTS not amps.

I’ll bet he could get a “Charge” out of that!

Wow,,,yes mostly for faxing.

Nope, I bought two of them and they gave me a price break for buying several items. They are in factory sealed boxes. Not labeled “AGM“ I picked them off of the pallet myself. Opened them up to inspect them before I bought them. They have some cool stuff there. (While supplies last). I picked...

I had a similar issue. What I found is don’t press and hold the activation button. Press and release it quickly one time. Thats all it took for me. Also, make sure you are using the correct port. Initially the button should be a dim blue. Once activated it is brighter. I also bought the remote...

I tried talking to tech support at AIMS battery and they really were not any help. I haven’t tried PD yet. That’s a good idea. I’ll shoot off an email to them too. I think a lot of employees don’t really know what the difference is among battery technologies. I’m certainly no expert. I have been...

Mine was never exposed to direct moisture or hose during the time I owned it. Even during rain showers the battery stayed dry from what I could see. I did check it once or twice. Some on this group have suggested a phenomenon they call ”pumping” whereas the cells as they heat up during usage...

Yes, That was my first ISP.

Actually not, mine failed in 6 months and they wouldn’t return phone calls or emails. They did not stand behind any kind of warranty. I ended up repairing the battery on my own by replacing the BMS and new case. Once I opened it they would not do anything. That part is understandable. I spent a...

Thanks Steve, That’s good advice. I kind of did that in the beginning. I had my system up and running for a few weeks and everything was fine. I was charging via two 100 watt panels between 7 and 9 amps at home and 10 amps in the desert. I could run the inverter for 4 to 5 hours in the evening...

I hope you washed your hands after the interview after Dennis coughed into them a few times during the interview before you guys shook hands. Good interview nonetheles.

Does anyone know if Aimscorp is still in business? I’ve called them several times now with no answer. Only a prompt to select a dept. Then another prompt to leave a message. I’ve left them a couple of messages since last week and have called them a few more times without leaving a message. They...

Not a bad idea but the case would be huge. It wouldn’t fit the group 27 case.

I have an AIMS 12v 100ah LFP for my trailer. So far it has worked only ok for me. It appears to be the converter that’s causing the problem. It randomly goes offline when the converter is connected to it without being plugged into ac. I’m still in the process of debugging the issue. Their tech...

Is lithium ion synonymous with lithium iron phosphate or Lifepo4? The label on the battery is lithium ion. Their fine print call it lithium-ion phosphate. Model No. KS300 Battery Type Lithium-ion phosphate (LiFePo4)

Hi Will, Thanks for all of the great reviews. I’m curious if you’ve ever done one on the AIMS 100 @12v LIFEPO4? Don.

Hello all, Ive got several lithium ion packs made of 18650s. Occasionally they will go offline due to being at or below the minimum voltage per the BMS. At this point they will not take a charge either. If I read the voltage on the output side of the BMS it’s essentially 0 volts. On the Input...

Wow, that’s great that they don’t charge tax.

I think it’s a wait and see game. Bioenno has been around awhile and has a good product line. Not saying BB doesnt. I’m just not sure these batteries will make it ten years. No matter who the manufacturer is. My Aims battery was about 6 months old. When it finally died they wouldn’t respond to...
