ExpertPower 12V 20Ah Lithium Iron Phosphate Deep Cycle Rechargeable Battery

vb: I use these for my whole house electric start generator instead of lead acid batteries, and I used them to replace the battery in my car jump box when it died. The lithium iron phosphate battery is good for many, many charge cycles, which will give me years of service.

Mark R. Hinrichsen: UPDATE: After several attempts I finally got in contact with "support". After numerous emails, I sent in the battery for testing at my expense. After not hearing anything for some time I had to contact them to get a status. They said my battery was able to be charged and discharged with no issues using their charger. I asked if they had done load testing on the battery but I did not get a reply. After a couple weeks they finally sent my old battery back to me. I did purchase their charger and charged my old battery. The first time I used the battery using my ham radio, after a few minutes the radio would shut off which is what my issue was to begin with. I sent them another email to say I still have the same issue and there was a specific reason I asked if they load tested the battery. That was about a week ago and I've never heard a response. So much for the world class support. This battery is probably okay for QRP operation on the ham radio but that's about it. So if you have any issues with this battery, don't expect a lot of support from this company. Original review. I have 2 of these. Purchased on in Mar 2022, had about 80 cycles on it for Ham...

Stan: You needed special charger to charge in series circuit into 2 of 12 volt LiFePO4 battery. I average 27 volt instead of 25 volt from lead acid battery for small, Drive Phoenix scooter. The speed were from 4MPH to 5MPH plus much higher torque as this scooter really climb firmly steep hill without bogging down. The range that nearly double. This battery is costly but it's really worth it. To me, lead acid battery that really suck. Less than 3 years later, one of battery were sagging at lower voltage. I may use the old weaker lead acid battery for solar use for lighter duty use with 20 watts solar panel with charging controller.

John: I am using the Expert Power 20ah LifePO4 battery for a portable crossband repeater for search and rescue. The light weight lithium battery was perfect in cutting down weight of the repeater. The up front cost is bit more than a SLA, but it's well worth it. They best part is you get ALL 20ahs of LiFePO4, where SLA is maybe half it's advertised capacity.
I did a trial run, with the repeater pulling about 4 amps on transmit and .3 amps on standby. The repeater was on and actively transmitting a busy local channel. I expected maybe 8 hours of run time till it got low. It's been going for 12 hours and is only down to about 60% capacity! I have an Expert Power 18ah SLA and you'd be lucky to run a radio for 6-8 hours before the depth of discharge got to low.
Thanks Expert Power for a great battery at a great price. It is very well constructed, durable, and I expect it to last for a long time!
