Club Car Yellow Battery Light Flashing

This is a very nice headlamp, without two levels of white light, a red light and a flashing red light.  Having the battery pack on the back makes it much easier to balance and the straps are adjustable over a wide range.

As many others mentioned in the reviews, these batteries are now new old stock, as the newest ones were made in 2022 and will arrive completely discharged. DO NOT give up on them - the charger will initially show an error (chamber and calibration light flashing) - keep taking the battery off and putting it back on, and eventually it will start to charge. The key is to not leave it in the charger if the charger is showing the error code, you have to remove and replace the battery until the charger shows that it is charging (chamber light and 50% light flashing). After a few hours the 50% light should glow solid and 80% should start flashing, and eventually it will charge fully

My APC UPS sounded off every few hours with beeps and a flashing red light to let me know it was time to replace the battery. I ordered online and the battery arrived sooner than expected. I installed it and it's been working fine since. The part I especially like, I didn't have to shut everything off to install.

I bought this a month ago when the battery died (I unfortunately did not notice the low battery flashing light indicator). The replacement battery arrived very promptly, was easy to install, and my backup is operational again — and just in time because a tornado hit here a few days later and I lost power for 8 hours.

but it is unsettling to have the upstream light flashing

[This review was collected as part of a promotion.] I am rating the JBL Party Box Club 120 with 5 stars but with one exception....that is, the Club 120 is almost 25 lbs. If the buyers intention is to carry the speaker more than a couple of minutes I believe this should have integrated wheels and a telescoping handle. The fold away handle is very convenient and stores nicely. The sound is good quality with nice bass (2 x 5.25" woofers, 160 watt RMS) and the light show adds to a party, celebration, or get together atmosphere. The Club 120 is now my go to portable speaker system because the sound quality is really good, the bluetooth for allowing me to use a headset works well, and I love the compact size. There a couple inputs for microphones and even a guitar input. This has an impressive 12 hr battery life (removable battery so you can buy a spare) and a splash proof rating (IPX4). Connecting to the JBL is super fast and if you have other Partybox speakers you have the ability to link them all together. The Club 120 fits nicely into the trunk of my car as well. Impressive sound, portable with 12hr battery life, somewhat light weight, nice light show options, and it even has 3 DJ sound affect buttons.

Back panel in black is aluminium, yellow sides are plastic, has a nice solid feel to it with these materials. On full power, getting around 30-40 mins before a charge is required. Taking battery off back is a bit hard without it hitting the back of the battery area, recommend placing a small strip of rubber so it cushions it. Mainly used for some macro work, product photography. As light has a built in diffuser it has a soft nature to it, covers about 160 degrees. If your looking for a more hard type of light i would get something else or a light with a removable diffuser. Wish the light came with a small carry pouch or case.

It charges a battery using your car. Not much else to say.

Seriously, this thing is great. Just plop in up to 2 batteries, tells you their status and juices them up. They still have a good load, just take out the battery and skip the charge. Very easy to manage your set of batteries. Clear indication of battery status no reading, arcane, flashing / not flashing, is that amber or orange.... Works well in car also and does not require a power brick just a universal 2 prong power cord. Charging is quick but not overly (quicker = less battery life due to the heat). I have use mine with Fujifilm X I understand other adaptors are available. Most fujifilm users have or should have multiple batteries: I Higly recommended this

Great light to keep in car.
