ExpertPower 6 Pack 12V 10Ah Lithium LiFePO4 Deep Cycle Rechargeable Battery | 2500-7000 Life Cycles & 10-Year Lifetime | Built-in BMS

Good quality product. Worked better than expected.

Perfect! Takes a charge very well. Would definitely recommend.

The battery went kaput about 1 year, 6 months. I did not abuse the battery.The other battery I purchased is still OK, so your mileage may vary.

I bought 2 of these batteries to build a back up power supply for two applications. The first was to run my small QRP ham station in a box that was intended for use during hurricane season here in Florida and the second was to power my cable modem when the power went out (happens a lot here in Florida). The batteries, installed in a plastic box, (purchased from Amazon) worked excellent for either purpose. However, one day, they simply stopped working. (zero output) While unsure of the actual failure I suspected I had shorted them our during charging and felt sure I now owned two bricks.I sent a note to the company and during a long series of exchanges i found that the built in BMS likely went into a safety mode and if I put a small charge at 14.4 VDC i might recover them.Sure enough the Batteries came back to life and they work perfect.I sure never expected that .... I asked for and received the specifications for the BMS. After reading the specs and further discussions with their tech in California I found there were numerous protections built in and the price for the batteries is very justified. Definitely would recommend them.

Bought two batteries; are working well. Charger quit after three uses.

Light weight, discharge was smooth, recharged timely. I use for portable power for telescope and ham radio. So far they perform better than heavy gel cells. Hope they live up to their longevity claim, because they are more costly than other battery types.

I had to use "fillers" to take up space inside the battery-pack. The batteries work well and are MUCH less heavy than the gel batteries.
