## Questions & Answers

**Q: Does this have a battery management system (BMS) built in?**
A: I found the data sheet on this battery. It does have a built in BMS with cell balancing, over-charge, over discharge, over
current and over temperature protection. Check out the full data sheet here: https://p.globalsources.com/IMAGES/PDT/SPEC/170/K1167638170.pdf

**Q: There is conflicting information on whether these batteries can be wired in parallel (connected to double amp-hours). Can someone please clarify?**
A: For the record, I have six 6-AH batteries in parallel for 36 AH, not six 8-AH ones, so no, I don't lose a third of the AH's. I see now that the smallest of these is now 8AH, but I bought mine when they sold 6's.   And NO, there is not only one way to wire in parallel.  A better way is to use the balanced way as I indicated.  Not sure where the "one way" comment came from, I suppose just never having heard of the "balance" wiring technique.

**Q: What is the CCA on this 20ah battery?**
A: If you read the description of this battery you will see that it is a deep cycle battery. Deep cycle batteries are not intended to be used for starting applications. They are not meant for high current such as what happens when starting a motor. They are meant for their current draw to be long and slower. That is why there is no CCA rating for this battery.

**Q: Have anyone used this as a ups for computers?  i want to get rid of those home ups that i routinely discard every two to four years.**
A: There are two problems with using these for any UPS that uses 24V wiring (or higher).  

Wiring multiple batteries in series will mean that they will become unbalanced over time.  I solved that problem with a battery equalizer, about $20, a simple device that continuously equalizes the individual batteries in series.   

The other problem is the BMS LVC (low voltage cut-off) in these batteries.  If the UPS fully discharges the batteries, the BMS will shut off and will not turn on again until the UPS supplies voltage.  However, my APC 1400 RMNET will not supply voltage until it detects voltage from the batteries.  So, you need to manually jump-start the batteries after that event, which is inconvenient.  

There may be a way to hack this by using a low current isolated power supply that applies voltage to the batteries all the time just in case, or, perhaps, on a one-shot timer, but this is getting too complicated and poses electrical risks.

    Using in an APC Smart-UPS 1400
  

*by A***M on Reviewed in the United States on 29 June 2021*

Or perhaps I should say "using them ON a UPS", since the 20Ah size don't fit inside.There are caveats to using these for a UPS.  For one thing, only commercial UPS units are designed to run on batteries for extended periods (personal models can overheat).  Also, my Smart-UPS cannot understand their voltage curve, so I had to disable low-battery shutdown and all alarms altogether.  It works fine, but it thinks the world is ending.  I wrote a blog post about it on tech.akom.net if anyone wants the details.Also note that if these have a 1C (20A) max discharge rate, they are not adequate for my UPS at even a 50% load.  Mine normally runs at only 6% load (that's about 5A) so these are perfect.The batteries arrived at 13.20v each, exactly.I ran a load test with UPS at 42% load (which is about 23A from the batteries and about 450 watts at the UPS output), and they held up fine, never dropping lower than 12.1v.  They didn't get hot, though the 10 gauge wires did a tiny bit.  After 30 minutes of this, their no-load voltage was 13.0 (3.25v per cell), and that's starting from a voltage of 13.95v per battery (UPS charge voltage).  That's still quite high.  Since I only intend to run at 6%, I should have about 7 hours of battery life, which is insane.With 2000 charge cycles (as opposed to about 5 that I seem to get with Lead-Acid), this is a worthwhile investment, and it's only about 1.8x the cost of lead-acid batteries.  Note that since I'm using them in series, they can become unbalanced over time.  I haven't had them long enough to know.  If this is the case, I may need to balance them manually (maybe once a year?).I'll update if there are any developments.

    Sorry Folks, do not recommend BATTERY....ahn.....customer service great!
  

*by J***R on Reviewed in the United States on 20 January 2024*

Update to this review. As I stated below got a replacement battery [1] for the 2 that failed. 6 months later the replacement failed as well. Wont hold a charge. 3 strikes and your out!Bought my first battery in 2022. replacing a lead acid battery on my solar system in my shed. Worked well. As I added more electric power lawn equipment I thought I would up my capacity and bought another in 2023. Results; in September of 2023 the first battery stopped holding a charge [after 21 months use] and in December the second battery stopped holding a charge [after 9 months use] not great. Wrote to the company thru Amazon. They immediately responded and sent me 1 new battery. So, should it last more than 21 months? I think so. But for the great customer service they get 4 stars. I will update this review on how their replacement battery does.

    Fantastic light battery for scooters.
  

*by M***. on Reviewed in the United States on 6 January 2023*

Bought these to convert our 24 volts scooters from lead acid to incredibly light lithiums. They hold their voltage all day at Walt Disney World. I just cratered one of them because I used one of the two batteries combined to produce 24 volts. Using it as a 12 volt battery to run a test on another device I manageg to run the battery down to nearly zero volts. That is suicide and abuse, not the battery fault. The scooters will actually shut down if the voltage gets below a certain point so will not damage the batteries. Using one as I did was my fault. I had a charger on it but the charger could not keep up with the load.I have had this set of batteries in my scooter exactly one year. One of the batteries that was not abused seems to be fine and is charging great. I am going to replace just one for grins to see how long I can get out of these. I like these so much I bought a set for my daughters scooter. We now have three scooters running with these. They are amazingly light. Less than a third of the weight of lead acid.Most batteries in the past survive just a few months. If we got six months out of them we were lucky. We tried all kinds too. AGM's, etc. These just peg the voltmeter without a load, that is driving them because the voltage is just a bit higher than lead acids.Amazon is selling them at a decent price but it would be less painful at around $50 each. So try not to kill your batteries. I know, batteries are never really owned, just rented. All of them die.
