GNB 4000mAh 4S 10C Li-ion Samsung 40T Battery

Overview:

The GNB 4000mAh 4S 10C Li-ion Battery is a high quality Li-ion battery pack made using Samsung 21700 40T cells, manufactured by Gaoneng, more commonly known as GNB. It features a rating of 10C for constant discharge. The battery is fitted with an XT60 connector and XH2.54 (5 pin) balance connector.

This GNB battery is 4S rated and is suitable for low current, long range type vehicles.

** IMPORTANT INFO – These batteries are NOT suited to high current draw applications like 5″ racing quads as you will destroy the cells. Keep in mind the discharge rating is 10C and not 100C+ like a LiPo. Its designed for low current draw applications such as single motor ultra light weight long range FPV planes. The achievable discharge capacity will also vary dramatically depending on the discharge rate. At 10A you will not get anything like 4000mAh. The only way to achieve 4000mAh is to discharge at a VERY low rate over a long period of time and to a lower then normal voltage. If you have questions about this type of battery chemistry then please call us BEFORE ordering. **

** WARRANTY – These packs are trivial to destroy by pulling more then 10C out of them as such the warranty is even more stringent then our normal DOA warranty. The warranty on these packs is cell voltages only (i.e to cover dead cells on arrival) and you must notify us within 24hrs of receipt **

Warranty Exclusion: Please note that as batteries are “consumables” we only provide dead on arrival warranty. The maximum capacity of all rechargeable batteries fades with time depending on application and usage patterns. This is considered normal – therefore, a change in battery capacity is not covered under warranty. Battery life is not warranted and will vary depending on usage.

IMPORTANT: Never charge batteries unattended or near anything flammable! Constant supervision is required as batteries can be dangerous when mishandled. Please take LiPo battery safety seriously, please see our safety sheet
