Frequently Asked Questions

Yes. The datasheet lists campers and RVs among its intended applications. With 300Ah capacity and 3.84kWh of stored energy, it is suited to larger 12V auxiliary systems where longer runtime is required.

The battery supports up to 200A continuous discharge, while 150A is listed as the recommended discharge current. The appliances you can run depend on their total current draw, inverter efficiency and the design of the overall 12V electrical system.

Runtime depends on the connected load and how much battery capacity is used. For example, a 500W load would theoretically use about 0.5kWh per hour, but real-world runtime will be shorter due to inverter losses, wiring losses and other system factors.

Use a charger suitable for 12V LiFePO₄ batteries with a CC/CV profile. The specified charge voltage is 14.4V ±0.2V, with 60A listed as the recommended charge current and 200A as the maximum continuous charge current. 

Yes. Solar systems are listed as an intended application in the datasheet. The solar charge controller should support LiFePO₄ chemistry and operate within the specified charging voltage, current and temperature limits.

The current datasheet does not specify the maximum series or parallel configuration. Confirm the required system arrangement with Humsienk before connecting multiple batteries together.

The 200A BMS provides over-charge, over-discharge, over-current, over-voltage, temperature and short-circuit protection. The datasheet confirms these protection functions but does not provide individual cut-off or recovery thresholds. 

The datasheet identifies this model as a Smart Edition, and the product graphic on page 1 also carries a Smart marking. However, it does not state whether monitoring is provided through Bluetooth, an app or another communication interface, so the connection method should be confirmed before publishing this feature.

The specified discharge range is -20°C to 60°C, while charging is specified from 0°C to 55°C. The BMS includes high- and low-temperature protection, but the exact protection trigger and recovery temperatures are not stated.

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!

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.
