Frequently Asked Questions

This battery is designed for compatible 48V low-voltage inverter systems and has a nominal voltage of 51.2V. Before installation, confirm that your inverter supports the battery voltage range, 57.6V charging requirement, charge/discharge current limits and any required BMS communication protocol.

The battery supports up to 200A continuous discharge, which is approximately 10.24kW DC at the 51.2V nominal voltage. This does not automatically guarantee compatibility with a 10kW inverter; inverter efficiency, surge requirements, battery voltage under load, cabling and BMS limits must also be considered.

It can provide substantial storage for an off-grid system, but whether 15.36kWh is sufficient depends on your daily energy consumption, solar generation, inverter size and required backup duration. Larger homes or high-consumption systems may require additional storage where supported.

Runtime depends on total load and system losses. As a simple example, a constant 1kW load would theoretically consume about 1kWh per hour, but actual runtime will be lower once inverter efficiency, wiring losses and usable battery capacity are considered.

Yes. Solar systems and off-grid systems are listed as intended applications in the datasheet. The solar inverter or charge controller must support a 51.2V LiFePO₄ battery and operate within the specified charging voltage, current and temperature limits. 

A larger battery bank may be possible, but the current datasheet does not state the maximum number of batteries that can be connected in parallel or series. Confirm the supported configuration and communication requirements before designing a multi-battery system.

The battery uses a metal enclosure and carries an IP54 rating. Because the unit weighs approximately 118 kg, the installation location and mounting or support structure should be planned accordingly and should follow the battery and electrical system installation requirements.

The integrated 200A BMS provides over-charge, over-discharge, over-current, over-voltage, charging and discharging temperature protection, and short-circuit protection.

Un service après vente extraordinaire…
Après une année complète d'utilisation sans problème, j'ai du communiqué avec humsienk car la batterie semblais avoir une petit problème de recharge, ils ont immédiatement pris action afin de m'en faire parvenir une autre pour que l'on puisse finir la saison de camping. J'ai eu un service extraordinaire avec Chrissy, elle a été empathique et réactive. Merci encore a toute l'équipe de Humsienk pour votre support.

Good shopping experience

From start to finish took a bit of time because I did have a warranty issue (not the fault of Humsienk). It’s all by email and took a bit but it all worked out. So far, I’d purchase again

16kw batteries are life changing

The simplicity and styling of these batteries are far superior than others on the market. Can’t wait to try the new 32kw battery coupled with a pair of 12k inverters

idzlldi Support is no existent

By all indications the idzlldi battery line is made by Humsienk? I've reached out to their email support many times with zero responses. I just purchased the idzlldi 12 Volt 314 amp battery and have questions. I'm very concerned by the last of response. Looks like I made a bad decision!

Humsienk inverter & serverrack battery

Well i do enjoy our Humsienk serverrack Battery 5120ah
Really wish i had recived my second Battery $599.00
Now i do want this inverter also
It is 8000. But i dont go over 3000 watts
Really nice Humsienk Inverter
I only have a few solar panals 4- 400 watt & 3 320 watt
So loke 2500 watt solar max
Would Humsienk understand the issue im under here in Manville
Would you offer me a special for one inverter & also one serverrack Battery 5120ah
I do have one Humsienk battery
Please
Thank you everyone

48v 100a/h lithium golf cart battery

Just bought one of these batteries to use in my wife's golf cart / hunting buggy. This thing is well built and heavy. It's every bit of 90lbs. So far the battery is working great. Took the cart out for a couple of 5 mile runs and this thing only shows using about 10% of charge each time. Well worth the money to swap from lead acid batteries to this. Only tiny gripe is with the supplied battery meter. It's not very bright and you can't even see it during the daytime when the sun is out. Daylight just washes out the reading so I have been using the app to monitor the battery status. App works great. Overall, very pleased with this battery.
