Frequently Asked Questions

It may suit selected 48V lead-acid versions of Club Car Precedent and E-Z-GO RXV. The system class is 48V; the battery’s nominal voltage is 51.2V. Check your cart’s year, controller compatibility and the 593 × 266 × 217mm installation envelope, with terminal clearance and secure mounting. Factory-lithium versions require separate compatibility assessment.

The battery stores 5.12kWh nominally; an 80% discharge window gives approximately 4.10kWh before losses. The datasheet provides no validated distance or hole-count test. Range depends on terrain, passengers, speed, tyres and vehicle efficiency. For planning, divide available energy by your cart’s measured energy consumption per kilometre.

The continuous battery-current rating is 200A. Hill starts, heavier passenger loads and upgraded motors can increase demand. Check sustained and start-up battery-side current with your installer before changing controller settings. Peak discharge current and duration are not provided in the datasheet, so surge capability needs confirmation for the intended vehicle.

One suitable 51.2V lithium battery can replace a compatible 48V lead-acid bank, such as six 8V, eight 6V or four 12V batteries. The conversion needs appropriate mounting, cables, fusing and charging connections. Check the original onboard charging controls and battery gauge for lithium compatibility; additional adaptors or configuration may be required.

Use a manufacturer-approved LiFePO4 charger. The datasheet specifies 57.6V ±0.2V CC/CV charging, recommends 20A and limits continuous charging to 100A. An existing lead-acid charger requires compatibility confirmation. From empty, capacity/current estimates are about 5 hours at 20A or 6.7 hours at 15A, plus the final charging stage and any load allowance.

Use a properly rated 48V-to-12V DC–DC converter for 12V accessories. Check that any existing converter accepts the lithium battery’s operating voltage range and can supply the combined accessory load. Review accessory wiring during the conversion. Connect 12V equipment to the converter output, rather than directly to the battery.

Yes. Install the official Humsienk app for iOS or Android, enable Bluetooth and connect nearby. You can view charge level, voltage, temperature and charging status. Once installed, local Bluetooth monitoring does not require mobile data. The datasheet does not specify a guaranteed connection range.

The IP65 case provides protection against dust and water jets, with immersion excluded. Keep terminals protected and choose a secure installation within the approved temperature limits. Charging is specified at 0°C–55°C and discharging at −20°C–60°C. The BMS includes temperature protection, but exact trip and recovery thresholds are not listed.

Batteries purchased through Humsienk’s Australian website carry a five-year warranty from the original purchase date for covered defects under normal use and proper maintenance. For support, email service.au@humsienk.com with your order number, issue description and relevant photos or videos. Normal wear, misuse and improper installation are excluded, subject to the published warranty policy.

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

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.
