First of all shipping was really fast, the batteries arrived a day earlier then expected. exterior packaging was heavily damaged from shipping, but due to the very well done interior package protection, no damage was observed to the batteries themselves. Being very new to this battery technology, I was a bit unsure about connecting to my existing system, but everything seems to be working OK. The claim about charging 5 times faster than conventional, does not seem to be working out for me. maybe twice as fast would be more accurate. I have not had a chance to test them for solar charging as we are in the dead of winter and we have yet to have enough sunlight to make a difference. It is too early to say how they will perform long term, but they are OK at the moment, but the claim was that these batteries should be compatible with the system I got and they do not quite meet my expectations, so I can't give them a five star rating yet. I am new to this technology so it is a learning process. Cost was very reasonable and with free shipping and ten year warranty, I am hopeful that I made the right choice, To be determined.

I got 5 of the 24V HAWK - LiFePo4 - 170Ah - 4.3kWh to take advantage of the free shipping - substantial savings on these heavy items. This model was still a manageable size, and the driver had no trouble getting these off the UPS truck by hand. They are exceedingly well packed and arrived in perfect shape. These replace a giiiiiaaaant bank of lead acid batteries at my home, and should hold us for a week with no sun or grid power.

I got good support from the people at BigBattery; when UPS said there was an issue with the shipment - BigBattery handled all the communications and took care of it all. painless!

I bought two hawk max batteries 24 volt - been using them non stop for the last two months running most of my condo- i have these batteries paired with the Victron inverter/charger and 4 Victroncharge controllers - No issues at all and with the sunny weather, my solar keeps them charged. in fact I only had to use my charger 4 times in 3 weeks due to rainy weather. I like the built in battery meter, fuse and on/off button (saves you money) - the built in battery meter matches the Victron battery meter spot on.

Bigbattery has the lowest price (per kWh) off grid solar batteries around. I own 4 of the 24V hawks and they have been golden. Customer service was easy to deal with and the shipping/packing was excellent as well. I wasn't excited about the Anderson connectors at first but after using them for a while, I have to say that I will NOT be going back to the lugs. Anderson connectors are way easier to work with. Oh yea and the fire suppressor that is built into some of the new models is also a great safety feature that I haven't seen anywhere else. Great value for your dollar!

I called them and to my surprise a person answered the phone - and it was a very pleasant chat. Kris answered all my questions and connected me with tech support for helpful suggestions. BONUS - My 24 volt Hawk batteries arrived the very next day!
Great job guys and thanks,
Robert
