So I bought this battery is tested and tried out! And it worked out terrifically perfectly! I need six more two more right away to complete my system I think to keep my air conditioner running for 12 hours and then I like to buy a few more for eextra power during storms and whatnot.! This battery worked out perfectly I can't wait to get two more and then four more and I'd like to try one to put in my golf cart! Right now I'm using it for my solar system for my refrigerator and my air conditioner but I only have one 100 amp hour smart battery obviously that's not enough! Terrific battery thank you! I almost forgot to tell you! If you go to will prowse on YouTube he completely takes the battery apart test it and everything on video in real time and tells you how good the battery is!

Good timing

After much back-and-forth and waiting on e mail responses, a simple adjustment of the battery management system app settings resolved the issue and the battery is now operating normally.

A "chat" line might have resolved this is one day instead of weeks and some direction on using the app and its settings with the packaging likely would have prevented the problem in the first place.

Appears to be nothing wrong with the battery; it does what a battery is supposed to do.

Arrived multiple days sooner than expected

Easy to work with customer service

Shopping for this battery was easy, click ,click and on its way.

This battery / charger combo was so awesome for my 2021 club car!!!! the shipping box was very well packed!!! fed-ex had smashed the whole bottom of the battery box!!!! but you guys packed it in very nice dense foam!!!! no more led acid battery's for me!!!!!

Ok shipping arrived my battery 12v, 100ah.. 👏

Humsienk customer support is amazing. I can't recommend them enough.

Easy pick up

The battery arrived on time and has been working great. I added it to 3 - 200 Ah batteries so it would equalize with them and tell me what they are doing, how full they all are. I was confused because my battery bank dropped to 13.3 volts fairly soon after charging. But they will be at 13.3 V from almost 90% to 30% full, so the voltmeter to measure their charge is useless. The Bluetooth app tells you exactly what % full, how much is going into or out of your battery. You can also use the app to shut off the charge and/or discharge function of the Bluetooth battery. Meaning you can leave it fully charged as a spare until you need it. This is very important on a boat system, to have a backup.

Week2 of it and it's holding up great. Highly recommend

Timely delivery, good product.

Everything great. Thanks

Good experience great product at an affordable price got the 314ah mini for our rv will probably get 2 100ahs for our boat.

I thought I ordered a battery with a charger. Contacted Humsienk via email they sent me a link to collect payment. Very smooth process. So far 5 Stars.

Had a problem withone battery BMS failed. Their customer service had me work through some troubleshooting procedures. They replaced my battery under warranty. No problem. Good company.

Easy ordering, quick shipment.

Toimitus oli nopea, mutta lähetyksen seurantaa voisi
parantaa.

Easy shopping on line. Great pricing. Great shipping time. Nothing beats free delivery to door for heavy items!

Just perfect, in time and delivery

The product arrived defective. Customer service is very slow to respond and when I refused to start fixing it myself I haven't received a response for 5 days.

Bardzo dobry akumulator, spełnia wszystkie oczekiwania (będzie zamontowany do kampera). Aplikacja czytelna,łatwa w obsłudze i bardzo ułatwia obsługę. Czas dostawy był wydłużony , ale warto było poczekać. Polecam.

With more budget options available i picked humsienk because of reviews based on teardown videos on YouTube. Glad I did, these batteries are underrated and work great!! Even tested out customer service because of a shipping issue, and they respond right away!

As more competitive options become available i picked humsienk because of watching teardown videos and cell tests from this and other budget brands. Had a shipping issue and the service support team was right on it, helping me fix it and sending me my batteries. After some tests upon arrival im glad I picked humsienk

I have never received an order.
