36V 100Ah Golf Cart LiFePO4 Lithium Battery 200A BMS,NewtiPower 10000+ Deep Cycle Lithium Iron Phosphate Battery Great for Golf Cart, RV, Marine and Off Grid Applications

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.

Easy install, perfect choice with all the options out there. The hard wire connection to meter is the best over wireless. This unit also offers wireless option.

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!

Makes my pos golf cart feel like a Tesla.

The whole kit may be a good deal but it didn't or wouldn't work for our application. It was only after it arrived that we realize that the battery would not fit in the cart we intended to use it in. It was due to the frame structure. We immediately initiated a return only to discover that it was non-returnable.

Great units, Bench tested both a 2x12 + 2x12 in a 24volt series config and 2x12 volt in parallel for UPS Storage extensions. BMS did its job. Depleted unit to 30% on a 30 amp discharge cycle then charged. Came back up to 99% with a charger designed for GEL Cell batteries. In total we bought 6- 12 volt 100ah will buy again.

I'm using these on my solar setup and they work well. The seller sent chargers for them too. I'll probably be buying more to beef up the solar a bit more.

Light great power for size, and free charger by mail if you need one. Haven't used them yet for there for our camper. Will update when I do.
