24V 50Ah 1.28kWh Lithium Battery –  3kVA Inverters & Backup

24V 50Ah 1.28kWh Lithium Battery – 3kVA Inverters & Backup

Regular price R 7,999 R 6,999 Sale

Our 24V 50Ah Lithium Battery is a drop-in replacement for 2 x 12V 100Ah lead acid batteries in a 24V system. It has a usable capacity of 1.35kWh and an integrated battery management system (BMS) that protects the battery and ensures it’s long lifespan.

The usable capacity of 1.28kWh is the same as the usable capacity of 2 x 12v 100Ah lead acid batteries, since lead acid batteries should only be drained to 50%, where lithium can be drained to 100% of rated capacity.

The battery is made of ultra safe lithium iron phosphate (LiFePO4) cells sealed in a durable plastic enclosure making it water and dust resistant (IP55). The unit can also be mounted in any position. The battery has a minimum lifespan of 2000 cycles, warrantied for 2 years, with a design life of 5 – 10 years @ 0.2C charging or discharging.

Great experience with my purchase from using the online ordering platform to delivery...everything was seemles .

This really works well with Mecer inverters!

After buying one of these for my home Mecer 24V 1200W inverter, and proving it works perfectly, just plug and play (and set charger to 10A, not 20A), I recommended it to a colleague who bought 2 - the 24V and 12V 50A Lithium batteries for their home inverters. Low recharge cycles of lead acid batteries solved for years with these lithium batteries!

Excellent replacement for 2*12V 100Ah lead acid batteries

Works perfectly with my Mecer 1200W/2400VA inverter. No problems with cut off voltage because of internal BMS. And I'll get 1000's of cycles instead of 300 for lead acid batteries. The right solution for loadshedding
