The bracket is with two holes in M8 nut,provided enough screw .You just need to fix the provided M8 screw and wiring the J1–4 and J1–1 wiring as below show.Just notice that the voltage applied between display + and – should be limited to the range of 8–90V.

 

In Newzealand market,the average retail price including the lithium battery and matched charger is about USD3000,which is provided by our customer from Newzealand.

While the wholesell price of VTCBATT brand 51.2V 105Ah total kit is just below USD800,which means that the local Newzealand dealers have potential profit in selling VTCBATT brand golf cart battery.

For long life and low maintenance, LiFePO4 batteries are recommended. AGM and flooded lead-acid batteries are also common.
Lithium batteries have advantages in terms of maintenance convenience, environmental protection, and battery weight. As for the price, because the cycle times can last up to 10 years, the cost-effectiveness is also a good choice when averaged out.

Check Ah rating and voltage to match your cart and expected driving distance.Please contact our sales team at sales@vtc-energy.com with your specific requirements so they can help you choose the right capacity for your needs.

LiFePO4: 4–6 hours standard charge; We can configure a 20-25A charger for you.

LiFePO4 batteries are maintenance-free.You only need to charge the battery correctly.

VTCBATT golf cart lithium batteries are compatible with 99% of golf cart motors (controllers). You only need to select the voltage that matches yours, such as 36v, 48v, 72v, etc. (within a range). Then, ensure that the dimensions of your battery compartment can accommodate the entire battery.

Features include overcharge, over-discharge, short-circuit protection, and UL/UN38.3 certification.

Solar Energy Storage Battery FAQ

LiFePO4 (Lithium Iron Phosphate) batteries are the best option for solar storage due to their long lifespan, high safety, and deep-cycle performance.

VTCBATT battery has 6000+ cycle life based on 0.2C charge&discharge at room temperature.
VTCBATT insists in using brand new and Grade A cells,which can ensure the best performance of the solar energy storage battery.
Some competitor may use very used cells in very low price to get the order,which will cause lots of potential safety risk.
VTCBATT’s board member prohibits in using low quality battery cells.

Storage capacity depends on voltage (V) and ampere-hour (Ah) rating. For example, a 51.2V 100Ah battery stores about 5.12 kWh of energy.

Yes, most LiFePO4 solar batteries support both off-grid and hybrid solar systems, compatible with inverters from brands like Growatt, Deye, Victron, and Goodwe.
