Review: great little portable 12v battery - I’ve build a small battery pack for my Jeep using 2 of these to double the amp hours. I’ve been pleasantly surprised at how well they work. I use a 13.1v detector from car batter that turns on to charge this with a dc charger while driving and then i use 12v pigtails to connect to devices to charge or power from these batteries. When i turn off my car and primary battery drops below 13.1 volts the dc charger turns off and these power 12v appliances while parked. As they go on sale i may double up the pack. I also used one to power my fish finder on my kayak. So many uses for these little devices and the built BMS seems to handle the TX heat and mountain cool air in handling charge/discharge cycles.
Review: Great for Ham Radio on high power - Works really well. Used it with my FT 991A on SSB and FT8. I used it for 6 hours, constantly transmitting at high power and still had ~25% charge left after using. Works with a bunch of different connectors and easy to carry. Great value when it goes on sale. Feels more protected than EcoWorthy's other 20Ah battery.

## Questions & Answers

**Q: How long is it? Description says 10.8 inches and manual states 7.8 inches.**
A: Dear friends, I'm sorry, the size of this product is 7.8 * 4.1 * 4.3inch.

**Q: Can this be connected in series 24 or 48 volt?**
A: Dear customer，thank you for the question.
Yes , you can get 24 volts by connecting two of our 20AH outdoor lithium batteries in series or connecting four batteries in series to get 48 volts.
Thanks again for the question, have a nice day!

**Q: It it normal for the voltage to decrease over time? my new battery v decreases from 14v to 12v over relatively short time frame - bad battery?**
A: Yes, voltage will decrease over time.  Nominal battery voltage is 12.8V.  Charge voltage is higher, often 13.5-14.0V, but will decrease within several days back down to around 12.8V.  This is quite normal.

**Q: Can this battery power an air pump that draws 28 amps? I only need to pump an small inflatable boat once per battery recharge**
A: The 20AH battery can charge your inflatable boat once, but since the starting power of the air pump is relatively high, it is recommended that you use 50AH or 100AH battery
