2PACK 12V 135Ah LiFePO4 Lithium Battery Bluetooth Deep Cycle TCBWORTH for RV,Solar, Caravans, Boat

Have 4 batteries in series, 48v, and have discharged and recharged several times with no issues. Capacity I get is 134.4ah didn't use batteries for a few months and only lost 1ah to storage discharge, have it hooked up to a balancer on boat. Was expecting more discharge loss then what has been observed. Bms is a DP04S007L4S100A over current is set at 160a but I have not tested that out. Haven't opened the batteries. Ordered my batteries in April and batteries received were made Jan 3rd 2025. Tcbworth app is kinda ehh but https://overkillsolar.com/support-downloads/ is a excellent free app to use, don't edit the bms parameters... Currently would recommend.

Lighter weight. Great battery. I used in 48v marine set up. Love this battery. I know three others who have also purchased. All impressed.

these are for a 70lb thrust trolling motor. serious lasting power. I've not charged them but once and have used them. I believe I could troll for 3 solid days with these. Love the Bluetooth feature. App needs work. the repeated sign in is excessive for a battery. Should connect once and done like my ear buds. Thats my only complaint. On the water, no reception, and it wants me to log in to check. solution is do it the night before for now. amazed with the lasting power of these though.

The batteries are well constructed and high rating capacity for my marine trolling motor installation. Great replacement warranty as well. The price was right compared to others.

I charged the batteries one full charge and have fished 4 times and they are still strong. I have two hooked parallel to make 24 volts

Picked him up for my trolling motor have them charged up, but haven't had a chance to try them out yet. Delivery was fairly quick they were as described

I cannot get into the site to be able to bluetooth to my phone

worked great for like 4 cycles, then one stopped charging and outputting, used the correct charger ( noco gen 5) on the lithium setting. seems 1 of 4set of cells is not working. tried tcb worth customer service... they said its because they are in series and one will discharge all first before moving to the next. for any one running a 24 v system, you know that is total bs. I'm going to try to take them back to Walmart today

Don't order the tupac, because you'll never get two batteries.They send you one and then deny they didn't send you even that.You got photographs from the porch one battery.How long is it gonna take me 42 get one?It's been two months now.They suck

One of the batteries would not take a charge
