Excellent battery fulfills very well what it promises even working at 100% and very happy I highly recommend it

Don't waste your time. Bought less than a year ago and two of 4 batteries that I have purchased have already gone bad. Won't take a charge and are completely 100% dead. Any other fishing guides out there that need reliability, run. This isn't the battery for you. And customer service is absolutely disgusting. Slow as possible to respond and come up with a solution. At this point I just want my money back and they can come pick them up.Horrible.

Exceeds the 300Ah spec and has a generic Jiabaida/JBD BMS, fully configurable if needed.Balancing settings were not to my liking for LiFePo4, but easily changed.The low temp settings otoh were great and it pulled 200A for a good while without breaking a sweat.I have no clue why manufacturers allow balancing already at 3.300V, but it had a generous delta setting on top of that so it looks optimized to handle really unbalanced situations. I've seen worse decisions.

Works as i expected it would. Good price and good battery monitor system. When I charge full had a bigger voltage difference between cells ,but the bms did it job. One day later almost spot on the same. Should of put in golf cart sooner. My old batteries were getting week so thought I would go lithium. Glad I did. On ezgo put a piece of 3/4 plywood down in tray and battery fit right in front half of the pan. Total cost of change over was right around 600 bucks. Including battery ,a 36 volt 10 amp waterproof charge ,a 36 volt to 12 converter, and went with a battery shutoff switch to cut power from converter when lights not on. Also bought plu adapter to bolt in where the old charger went into.

I purchased this battery to run the 55 lb. thrust trolling motor on my small lake fishing boat. It weighs less than half what the lead-acid battery it replaced weighs and after trolling for 6 hours still held adequate power. This is a good low cost lightweight solution for trolling motor power.

I purchased the 12v 300ah battery to replace two 6v 75ah batteries in my RV. The new battery fit easily in the same spot as the old flooded batteries. The Bluetooth app works really well for monitoring the SOC. So far, so good. The battery was packaged nicely, and it shipped sooner than expected. I like that I can get 300 useable amp hours in the same space as the previous 37 useable amp hours. No more concerns about the battery dying while traveling and losing everything in the fridge.

Holds a charge, charges quickly, and it is possible to monitor through your phone. The app is very quirky and somewhat difficult to use as the instructions are not clearly translated in English.

This battery fits perfectly in one of my golf cart battery racks leaving the back rack free where I put down plexiglass and lights. Most batteries were 10.59 or 10.6 inches wide and would not fit in one of my rails. This one is about 10 inches wide and fits right in. I have av 2008 EZ GO 36volt golf cart. I saved almost 250 lbs in reduced weight from my 6 Trojan batteries to this one battery. Also this battery was 135 AH versus most 100 or 105AH so lots of power and range. I can go 21 MPH versus 18 and the best part is I can maintain that speed going up a hill. Could never do that even when I had new Trojan batteries. Been driving around for 3 days now and still have lots of juice. It blue tooth’s to your phone so you can see how much power you have left but I added a separate power meter. You will need a 20 dollar reducer that connects to the 36 volt battery on one end and gives you 12 volts on the other end for lights, horn, turn signal, radio etc if you have them. I have them. Take pictures and label all your 12 volt stuff, usually connected to two of your old batteries for 12 volts, do this all before you remove the old batteries. It made it easy for me.Also have some connectors for your wired as required. Great Battery for 699 dollars, not much more than 6 Trojan battery replacements and last 10 years versus 5 with more range, power, and lighter in weight.

Item arrived promptly, and well packaged. Was fully charged. Haven't had the chance to try it out on the electric trolling motor yet, so can't comment one way or the other just yet. Price seems fair to me.

We have bought 4 already and when we expand our battery bank we will by more. They run our lights, tv, fridge and 3 freezers. We just did our first winter with them. They worked fine even on our cold nights. Unless we had multiple cloudy days they worked great with our solar panels.Highly recommend for anyone living off grid or has a camp. And the price is right.

Alles hat fantastisch funktioniert. Vom Bestellprozess bis zur Lieferung. Mit dem Produkt bin ich bis jetzt zufrieden. Die Verpackung war in Ordnung.Allen berufstätigen Beteiligten vielen Dank und schöne Feiertage.

IMPORTANT UPDATE:Aug 2024: It is now a year & a half later & the batteries still work like new. Additionally, I bought one for my RV & 4 more for a solar array I installed. These have been charging & discharging daily for several months with no problems. That is a total of 8 of these that I have now & I am impressed that every one is performing perfectly, & they are about the least expensive brand available.One thing I have found is that when using them in a 36 or 48V application, they need a battery balancer to get them to charge & discharge equally. I bought a Li-time brand for both the 36V golf cart & the 48V solar system, & they now all charge/discharge at exactly the same rate, solving the problem I described over a year ago below. The 36V charger now charges them all at the same rate.Mar 2023: It seems that when the 36 V battery charger had cut off, the voltage was still there & gave the appearance of being over charged on the first battery to get charged. Upon realizing that after the replacement was installed, I now understand that batteries charge at different rates & when the first one reaches the 14.4V charge, the system cuts off. That left the other two at 13.24V & 13.45V respectively. I was able to individually charge them with my 12V, 4A lithium ion charger in 2+ hours each.This means that for a series connection of batteries, each battery needs its own 12V charge from either a multiple output charger or an individual charger to put 12V on each battery to charge them in order to get a full charge on all of them. I would suggest that you verify this & add comments to your description of the batteries so everyone is informed that a 36V charger will not fully charge all batteries in a series connection. I highly recommend the golf cart conversion as a great improvement over lead acid batteries, & this will allow them to all fully charge. Also, the company provided excellent support through the Amazon contact seller option. Other reviews claimed poor response, but I found them quite helpfulFeb 2023: I bought 3 of these to replace the 6 ea. 6V lead acid batteries in my '93 ezy-go golf cart. I chose this brand as they have been around for at least a couple of years & another review for a golf cart conversion was posted. The specs show them to be well made & price is excellent. I am extremely impressed with them as they do everything claimed in specs. First, they are 285 pounds (60%) less weight so the golf cart is now a go cart!! Also, the voltage stays above 12V during entire discharge so power is greater, speed higher. The range is much greater than new lead acid batteries would be, as there is much less cart to move and total power seems to be greater. It is as if it has power steering now.I bought a DUDHOIK 36V 8 amp Lifepo4 charger to charge them & it takes about 18 hrs to fully recharge them from being totally dead. I have a 36V gauge on the cart & it started dropping below 35V on acceleration just before going dead as a warning they were about dead. Otherwise the voltage was always between 36 & 40V.These batteries are longer than the originals & will not fit in the spaces for the old batteries. I placed pieces of 4X4 wood in the old frames & set the new batteries on them & used rubber bungee cords to hold them down with pieces of 1X2 to hold them from moving.The install was easy & seems to be working out well. The only unknown now is if they will last 10 years as rated. Time will tell. So far, this conversion appears to be a no brainer as I can also use the batteries in my RV or charge them with solar panels & use them to power my 2K pure sine wave inverter in case of a power outage. And what an improvement in golf cart performance!!I noticed that another customer, DamiJ, using these in a golf cart indicated a possible need for a current clamp. I have run these very hard through 2 full charge/discharge cycles, pulling a trailer, climbing steep hills, etc. & have had no problems with any limitations, so it does not appear this is needed as far as I can tell.

The battery came extremely well packaged and cushioned from possible transport damage. The initial charge on arrival was 13.1V steady. Once I allowed the battery to acclimatize, I placed a charger on it and proceeded to fully charge the battery until the BMS shut off the charger.It will be placed on an external electrical fence solar system and I will evaluate it's nominal 1280-1300Wh of capacity over the next few days of sun and snow.I fully expect a remarkable difference from my current lead Acid batteries.
