These are amazing batteries. Great power for the price and the BMS and lifepo4 chemistry makes them a robust option for solar systems where they are regularly discharged and recharged. I have purchased a dozen over the years and am really happy with them. Good customer support when occasional dead on arrival happens (they can get physically damaged during shipping or occasionally have weak welds between cells). I have always had great experiences.

Tripled my run time in a camper in series over the prior lead cell. Half the weight and hours more off grid.

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.

I recently upgraded my RV system with two 100ah BTR LiFePO4 batteries, replacing the old lead-acid batteries, and I couldn't be happier with the change! These batteries not only offer high and stable voltage but also deliver up to 2kWh of energy, which is enough to power my RV for an entire weekend getaway. During the installation, I ran into a few technical snags, but the customer service at BTR was outstanding. They were quick to respond and extremely helpful in resolving all my issues. Their quick and efficient service really impressed me. If you're considering upgrading your RV battery system, I highly recommend BTR's LiFePO4 batteries. They not only enhance the reliability of your power supply but are also much lighter, making them easier to handle. This upgrade has been a game changer for my outdoor adventures and extended camping trips!

First thing I did is test these batteries. Both tested over 100 amp hours. I have them paired up with two other batteries of another brand. They seem to be working well. After a few days of service they failed! I added them to my battery Bank and quickly noticed my capacity had not gone up. My charger started running all the time and the BTR batteries ended up taking down my whole system. I have had several of these and they have all failed. Customer service is okay. They will send you another battery that will fail in a week.

The battery is great. I have replaced the original lead acid batteries. I wasn't sure which LiFePO4 battery should i choose. I read tons of forums and finally decided to buy the btr lifepo4 battery. I am very happy with the performance of the battery, It's also very cheap, works and is rated as advertised. The batteries arrived earlier than expected. I have two batteries, one for my trolling motor and the other for my boat lights. So far I have needed one more 12v charger for my entire deck. A standard lead acid battery is 2x the weight of both of these batteries combined. They have performed wonderfully and lightened the load on the stern of my boat. Everything's going well.
