Li-Ion battery for underwater scooter Suex 14/37 XJT/XJS with Bluetooth 4.0 module for iOS and Android platform
Specs:
| Capacity | Energy | Max continuous discharge current | Weight | Dimension |
|---|---|---|---|---|
| 25.9V 40.0Ah | 1000Wh | ~30A | ~5.50kg | 178 x 220 mm |
Note: the cell manufacturers specs are higher than our recommendations above. It will not harm the battery to occasionally discharge at higher levels than our recommendations, but regular, sustained high discharge rates will degrade the battery more quickly and the battery voltage will sag at these high power levels. The Battery BMS is programmed to trip if cell temperatures reach 60degC during discharge and 45degC during charging.
The above capacitance values are for new batteries – stored and used at room temperature, charged with electricity, in the order of 0.5C. Low temperatures as well as high discharge values can significantly affect the battery capacity. Please note that the capacity will degrade over time and use.

Other:
- We recommend 4A charger (without fan) for capacity <29Ah or 5A (with fan) for capacity >30Ah compatible with UL and CE
- We use a high tech, fully programmable Smart BMS, which is rated for genuine 40A continuous plus, with a programmable over-current trip set to >60A (which is ample for the intended application). With our BMS you can view various battery data, such as: cell voltage levels, temperature, instantaneous charge/discharge current, capacity (genuine SOC, measured Ah and remaining Ah), data log, error indication (on models with matching LED panel) and it all links to your phone with a continually updated and improved App. Our BMS balances during charging (when charging and when at >50% charge) and therefore doesn’t require a full charge in order to balance. Auto power off function, auto power on and with a pre-charge function (no sparks, so long as the battery is powered off when linked to the controller).
- The battery uses a custom cellholder designed and manufactured by us, which ensures safety and reliability of the construction
- The battery life cycle is estimated for 500-700 cycles (1C discharging to 2.8volt, 0.5C do 4.2volt charging). The life cycle can be extended by charging the battery to 90% and limiting the discharge to 90%
- We use only new and original A grade cell for battery construction
- We build all our batteries from scratch in our factory, using non-standard parts that we design and manufacture. We do not buy batteries from brokers who sell them at the lowest prices to attract buyers. We do not risk when it comes to our batteries and your safety!
We give 1 year warranty for each battery. Our batteries are designed to be easily repaired if needed. We will repair all emerging problems and most importantly – everything takes place in our factory – in Poland! You do not have to worry about returning parts to CHIN as it does for other companies. The fact that we offer low prices does not mean that we do not stand behind our products if problems arise. We document the entire sales history, after-sales services and repairs / warranty replacement. More information is available on the website “About us” - There is possibility to build battery from other cells than those proposed according to the customer’s wishes – please contact us
