12V 330Ah Small-Volume LiFePO4 Lithium Battery,200A BMS,10000+ Deep Cycle Lithium Iron Phosphate Battery Great for Winter Power Shortage, RV, Marine and Off Grid Applications

I have two 36v golf carts that had 4yr old batteries that all needed replacing. I purchased two of these lithium batteries in May and so far they’ve been great. I was a little concerned about how long the 100ah would last but they actually run longer than the lead acid ever did. The price is much better than lead acid and I think it took about 300lbs off of each cart. Very straightforward install and the quality seems good as well. The carts get used nearly every day at a marina and I’ve never dropped below 40% or noticed any difference in power. Both carts seem a little faster and easier to maneuver which is probably due to the big weight difference. The charge rate is also much better than the old batteries (about 3 to 3 1/2hrs from 50%) I just mounted the chargers beside the battery under the seat and run an extension cord to them, which is much nicer than dragging the old heavy buzz box around. The display is also very informative and shuts down automatically after about 5 minutes if the cart is not being used. Time will tell how long these last but so far I’m very satisfied with these and will never go back to lead acid.

Charging: It came with ~25% charge, took 4.5hrs to reach 100%. I took the end off my old charger and can still use the same port. With this cart you have to “return” power from the port (a safety measure to keep it from going with charger plugged in), or hot-wire the lead. If you want to keep your old charger, or the plug is not useable, there’s plugs here for $15. Install: Easy, the hardest part was lifting the old batteries out (I bought a strap here just for that) and running the wire for the display (I followed the key switch wire). It fit right in the original rack (I put a piece of treated plywood under it, and did the same for the now empty rack). This battery weighs less than one lead acid battery, which is probably a major factor in Performance: I spun the wheels backing out of the garage the first time! New stock wheels & tires, it accelerates faster and seems to have a higher top speed. Bounces more, likely due to the reduced weight, I might need to find a way to soften the suspension. Range: I drove 2 miles and used 4% of battery according to the meter. ~40amps full draw, so I would think you could run ~2 1/2 hours continuously if the battery has the claimed capacity. Only complaints are about the display: The “power” button is hard to turn on and does not turn it off. It does time out pretty fast with no charge/discharge activity. Ideally it should have an “ignition key switch lead to auto on/off. The cable is super stiff, but the end plugged into the display is flimsy and there’s no way to waterproof. The included bracket has a protruding mount that is not adjustable - it took some tweaking/care to bend it for appropriate mount angle. Yes, I recommend this product.

Shipped fast and fit as described. Had to modify my holder to fit, but I expected I would need to. One month in, it’s been working great. Good takeoff power and the battery charges faster than the old lead acid batteries. LCD display is a must have too! Great to seethe level of each cell in the battery!

Purchased the Newtipower 12V 330Ah Iron Phosphate Lithium Battery almost a year ago for our RV--Rpod 178. The battery is much lighter than the lead acid the trailer came with and lasts much longer. We commonly camp off grid for extended times and coupled with 200 watts of solar power have never had a problem with power, even in November. This battery was less expensive too. Charge indicator on the top of the battery is handy too.

This battery was not fully charged when I received it. I charged it with a brand new LiTime 40 amp charger, which meets the battery’s performance specs and charging requirements in every way. (You have to request these specs from Newtipower - they are not included on the Amazon webpage.) I installed the battery and noted that it discharged by 30% within ONLY 20 minutes. This made no sense given the power (amp) draw was only 2.5 amps. A 30% discharge at 2.5 amps should have taken 36 HOURS, not 20 minutes. I recharged the battery again using a 200 watt Renogy solar panel with no problems. The battery then discharged abnormally yet again. When I attempted a recharge again with the solar panel the battery would NOT recharge at all (at ambient temperature in the 60F range). I contacted the seller to request a warranty refund. They refused and instead blamed me for the malfunctions. Bottom line: this battery is 100% non-functional and the seller will NOT honor their warranty. Also: no free returns so if you do return it YOU will have to pay big bucks for shipping 60 pounds back to the seller! Have filed an Amazon A-Z guarantee claim and hoping to get my money back. UPDATE: Amazon refused the A-Z Guarantee claim. The company messaged me to say they are sending another battery - no refund. Now plan on camping/travelling with an old AGM battery as backup. I just can't trust this product. UPDATE #2: Company promised a full refund over a week ago which has not been received. Interesting. The 300 amp hour battery I bought is no longer offered by the company on Amazon…

Nice battery. I installed it in my cougar 5th wheel, which has a small solar set up on the roof, which charges it up nicely when in the sun. The seller stated that a charger came with it "a $60.00 value". Never received it. Upon reviewing the pamphlet that came with it you have to "apply" for it via e-mail" which I did, only to be told that they were out of stock. So be aware, you will not likely see this, and should plan accordingly. Update on 9 Oct 23. changed rating to 4 stars. Upon seeing my review, the seller reached out, sent a charger, and gave me a $21.20 refund for having to wait so long for the charger. Also, the battery is doing great, a major improvement over AGM or golf cart batteries.
