These batteries are junk. I bought four of them converted my golf cart and now I have to replace another one. This makes two. They’re great for about a week and then they’re good for nothing more than a boat anchor. I wouldn’t keep buying them, but seems like one goes at a time now it’s in the shop.The and they say I need a new battery.

So far these batteries have done great. Took them to the beach to run my 24 volt trolling motor and would last all day in the saltwater fighting the wind and current. Great investment so far!!

Working great in my RV. They were labeled as a 24 series, but they are closer to a 31 series for size. they still fit nicely.

I purchased 2 of these batteries in the past for my boat and at 2 years old they are still strong. They run a pair of 12" subs, a second pair of 10" subs and eight 5" pod speakers for hours in 100+ degree heat (2000w+ of amps). They are holding up to the abuse of being aboard a 19' boat which can take a pretty good beating when the water is choppy. For charging I have twin 30A DC to DC Victron chargers so the stock 200A 12V alternator charging voltage gets profiled for the lithium bank as required. The engine still requires an AGM battery for cranking and is isolated from the lithium bank using a 2 bank blue sea battery switch. To manage this I added a Victron 25A AC OB charger setup as the AGM charger so I can just plug it in to shore power or an extension cord. This charges the engine batt and provides enough power for one of the DC to DC chargers.This setup was so sweet on the boat that I tried using four of these in parallel for my 48v EZGO TXT golf cart. Unfortunately my combination did not work since these are limited to a 100A continuous max draw when wired in series. I have a 36V GE motor that can handle 48v along with a GolfTech 550A 36v-48v speed controller and flooring it will cause an overload. The internal BMS will require you to disconnect or remove all loads to reset. I switched to four Epoch 48v 60A lithium cells providing 240A of running current when wired in parallel. That matches the stock FLA batteries max running current and doesn't overload. As this demonstrates to avoid tripping a lithium batteries internal BMS I may not need all 550A, which is the speed controllers max, but 100A is too little, particularly when starting upwards on a hill.That said, the support team worked with me to check all 4 of the batteries. The support teams engineers responded very quickly to help me diagnose the problems I was having. Once we knew this application would not work they helped me process a return. BTR has excellent customer support in my experience so if your having troubles deciding on which brand to choose ... these guys stand behind their product and you might consider giving them a try.

there is no warranty on this product they claim 10 year 1 year 4 months and they will not exchange don't buy cheap batteries they are junk and so is the company amazon should not let them sell this product also you can't find the warranty info on battery so you assume its 10 years apparently its not even 1 year 4 months . update they replaced the battery that was bad Thank You Anne you did the right thing! I bought 4 batteries and 1 went bad the others are fine , It looks like the battery has a 10 year warranty like more expensive ones do they should make it clear its only 1 year that is why only 4 stars
