Renogy 100Ah 12V LiFePO4 Battery, Mini Size Lithium Iron Phosphate Leisure Battery with 5000+ Deep Cycles, IP 65 and BMS Protection, Support 4S4P Connection for Caravan, Boat, and Off Grid System

First a bought a 50 amp dc to dc charger. That turned up and it was second hand. I bought two of these 200 ah lithium batteries through amazon and one battery charges to 100 percent and the other only 99.1 percent. Also they discharge at different rates and it puts them out of sync. Im not so bothered about that bit.Its the next bit you need to be aware of. Ive also bought the same battery though the renogy website, and they have took the money and said its shipped but it hasn't. So basically took my money and ran. Ive sent 50 emails and had nothing in return. It looks to me like, if you buy through amazon they will respond, but don't care if it breaks coz you would never get a response from them. They did send me 50 percent back on the charge controller, but only because they don't want to loose amazon as a selling point for now. Look on trust pilot for renogy reviews. Wish I had before purchasing. They are silly really, because if they sent me the battery I ordered through the renogy website, ide buy alot more batteries and solar panels and dc controllers. Looks like another company can have my business.Edit. The battery from there website did turn up eventually. Also I purchased another two 200ah batteries so 800ah total, but through amazon. Sally at customer services at renogy is awesome, she was on it like a shot, and asked for my order number. The batterys were sent by parcelforce 48. So all in all it took 4 days to receive them. What I have found out is, renogy web site has a different customer service than amazon renogy customer service. As Sally pointed out , that they don't deal with website purchases, only amazon purchases. So for now I will give them 5 stars for effort as apposed to 1 before.

I haven't used it yet but what I've experienced of all renogy products is that they are high quality for mid range prices. You will not go wrong with renogy products. Re the battery. This battery weighs 22kg. To get a similar amp hour usable capacity i would have to buy three gel 100ah batteries adding approx 60/70/80kg more weight! Plus the battery wont start to degenerated for longer too as it will achieve 1500 more extra cycles than that of a lead acid can achieve. Win win for just a couple of hundred pounds more. Plus it charges faster with my solar. Fabulous.

Not cheep and not worth it neither

Have three of these which power a 2000w inverter, faultless when keeping amps/watts within the range of batteries and inverter. Absolutely recommend 100%

Top quality, can't buy better!

These are solid and well made. Decent connectors. The smart 100Ah ones (without Bluetooth built in ) but bough BT2 dongle. Bought these direct from Renogy around 2 weeks direct shipment.Using them in an off grid cabin - solar charging at max 30AThe app works ok. -gives state of charge and charge / discharge current which is handy so you don’t really need a shunt to see power usages. Can disconnect frequently -pull down to refresh reconnects ok on iphone. Seems to balance self fine. BMS does shut off charging below ?5 degrees, and recovers when heats up.No issues after a year. Huge improvement on previous lead acid. I replaced half as much Ah and miles more usable power. No concern about running flat /damaging.

I have now unpacked the battery and hook up to my battery bank with 4 Renogy batteries connected in parallel. They don't allow series connection. I have noted that the battery drains too quickly. During initial test with all the batteries at the same voltage, the bank lasted 6 hours on air condition at max temp but today I've noticed it only lasted for 3 hours. Yesterday it drained too quickly without any load. I am guessing there is problem with the battery. I hope Renogy will step in and help.The battery is well packaged but I guess customer are charged for this. It is pricey given I bought it for about £500 last month in August. Also the battery discontinue at 10.9v. DoD is very poor in comparison to other brand.

Lets first look at the battery itself. Absolute sound performance so far, worth 5 stars. But everything else around was not quite instantaneous.The app itself did not connect to the battery until yesterday. I got notified of an update, downloaded it and voila. Suddenly the app does recognise the battery. I had already given in.Very similar experience with the delivery. The delivery date came and went. The shipping information said clearly that no item had been received by the shipping company. But on Amazon it was shown as on its way. Needless to say it did never arrive within the given time frame. I spoke to a friendly Amazon Representative who told me he had emailed Renogy. And right enough, suddenly communication was established and a few weeks later the battery had finally arrived.Generally I love the Renogy products, which tend to be of sound quality on the hardware side. But like others have recently stated, for further purchases I will consider alternatives as well. In specific as the latest notable price increases have pushed many of their products out of the corner where quirks can be justified via the lower price.
