Description

2nd Life LiFePo4 Lithium Battery Kit – 4P16S 48V 1280Ah 61kWh inc 350a Bidirectional BMS, 5A Active balancer

These kits are NOT for everyone – you should have a level of competence around DC power. If you do not know how to drive a multimeter or follow a wiring diagram, we do not recommend attempting to build a kit.

2nd Life LiFePo4 Lithium Battery Kit contains:

• 64 x 320Ah Cells
• 350a Bidirectional BMS
• 5A Active balancer
• Battery Links
• Mounting equipment for BMS & Balancer
• BMS Mounts
• Balancer Mounts
• BMS and Balancer wiring looms
• LiFePo4 Information guide

We do NOT, and will not use the run of the mill “smart BMS”  as we have not found them to be reliable enough for our liking – your BMS is a safety device (like a circuit breaker) – to offer a 5 year warranty, we need to have a BMS that we consider to be totally reliable

Heltec “hardware” BMS’s do not just randomly go to sleep or lockup – therefore happily doing the job they are meant to do (protect your cells from damage)

If you are wanting the monitoring features that comes with a “smart BMS” then we fully recommend a Victron Smart Shunt – which will give you the state of the battery etc. while leaving the hardware BMS to do its job in the background.
