As most of you know, we here in Eastern NC just went through a Small hurricane. As with most hurricanes, we had power outages, 7.5 hours for us. I have run a regular battery backup on my tank for a long time. Mostly to keep my light's timers from losing their settings and to keep a couple of pumps going. It works well except on my 2 pumps that are hooked to a JBJ wave maker. It seems that a pump that is already running when the power switches to battery does not have any issue but if it has to start up while on the battery backup it does have issues.
I am a photographer and use mobile batteries a lot in my work. One that I use is the Vagabond Mini Lithium (VML) by Paul C Buff. This unit has a Pure Sine Inverter powered by a lithium ion battery. When my pumps did not start up properly with the regular UPS, I suspected that it was because of the type of inverter used ( a Modified Sine Wave Inverter). I tried out the VML and sure enough, the cleaner power worked flawlessly. The JBJ alternates between 2 Aqueon 950 pumps every 2 minutes and with this power source they start up with no issues.
Another nice feature is that the VML can be left plugged in and will charge while running. So long as your drain does not exceed the charger, the unit will recharge the battery while still powering your pumps. I have had instances where I have had to leave the house to go to work while the power was out. So I hooked up the VML and plugged in the charger. It kept the pumps going while I was gone and since the power had come back on during the day, the battery was fully charged when I returned too. Not all of these types of battery power supplies allow you to charge them while being used so this is a nice feature.
Last night we lost power for about seven and a half hours and to my surprise, the pumps were still running when I woke up and there was still about 1/3 power still showing on the meter. Even though I am using it to run 2 pumps, there is technically only one running at the time since they are connected to the wave maker. So my estimate is that the VML would run 1 Aqueon 950 for about 10 hours by itself.
While the VML is a fantastic unit, Paul C Buff has just released a new unit, the Vagabond Lithium Extreme (VLE) which will likely rival that VML in every way (except size, weight and initial price). The VLE unit has a much larger charge capacity and the battery uses newer LiFePo4 technology, which allows the battery to be charged multitudes of times more than the older Lithium Ion technology. It is estimated that the service life of these (LiFePo4) batteries will be about 10 years compared to 2-4 years with Lithium Ion.
I am not sure how these units would perform as permanent backup power sources for the reef aquarium, though I suspect they would be fine. They both have a smart charging system that only charges the battery when it needs a charge. I usually leave mine charging until I need it (but I am not leaving it tuned on with a current draw on it all the time). If one was planning to use it in this way Paul C buff has great service and would surely be ale to answer your question.
But as a temporary emergency backup solution, these units are real life savers. I know my tank sure appreciated them
The VLM is priced at $239 plus S&H and the VLE is priced at $399 plus S&H. BTW, I am in no way affiliated with Paul C Buff, other than being a long time (happy) customer.
