12V 300Ah LiFePO4 Bluetooth Lithium Battery (HT) Professional High Current (150Amp Continuous drain BMS)

 The HT Series Professional are designed for High Usage applications and each 300Ah Battery can supply sufficient current handling to run a 2Kw inverter.  You can put up to 4 batteries in Parallel to support up to a maximum of 8Kw progressive current handling.  However we recommend that  5Kw would be a more reasonable system as some loads have a initial high start up current,  respecting this allows some headroom to avoid any potential surges activating the BMS Over current protection.   (Each battery has a pulse discharge of 320Amps for less than 5 seconds. with Perfect connections that would allow 4 batteries to tolerate a load of up to 1280 Amps! ) 

The HT battery is the same cylindrical cell Professional High Current battery but with Added BLUETOOTH connectivity to monitor state of charge, temperature, charge or discharge current etc. 

  Our professional high current batteries with 150-160Amp BMS* are designed and built to last, to deliver power above and beyond the capability of the lower cost models. This  over engineering is why we have not  seen problems with BMS Failure that is reported for some other manufacturers products, whose current handling is not sufficient for the demands placed upon batteries in typical situations with high load applications.


HT series lithium battery using LiFePO4 battery cells offer the following advantages:

◆ COLD CHARGE PROTECTION , together with App based temperature monitoring, limits battery charging below 0 degrees.

◆ Longer life compared to lead acid battery more than 2000 cycle life. Guaranteed greater than 80% capacity after 2000 cycles*of 80% discharge.  (1 cycle per day = 5.4 years!) with reduced % discharge the batteries will last much longer than this, with 4000-6000+ cycles usually achieved, depending on charge discharge rates and operation temperature etc. 

◆ Up to 60% weight saving

◆ 100% usable capacity (300Ah LiFePO4 approximately offers the same usable energy as a 160Ah Lead Acid battery) due to offering full voltage and current even when 80% discharged, compared to lead acid that typically only offers the required voltage at up to 50% discharged.

◆ More energy with 1/3 smaller size

◆ Less than 3% self discharging per month. 

◆ Built in safety protection with a unique Duel safe circuit board, ensuring Each cell is fused at its connection point in addition to the BMS protection.

◆ Zero maintenance

◆ Easy installation

◆ Eco-friendly

◆ Quality guaranteed,  5 year warranty up to 2000 cycles.  *As determined from integral BMS. Life expectancy is many times  longer than this with good battery management and conservative use.

◆ Fast charging, Charge at 20Amps in under 5 hours from flat with one of our high performance chargers. 

◆Can be connected in series up to 4 units to make 24V, 36V or 48V 100Ah system.  Using internal BMS no other controller needed.


◆ Can be connected in parallel up to 4 units to make 300Ah, 600Ah or 900Ah 12V system.  Using internal BMS no other controller needed.
