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.

Our team has many years of combined experience with lithium along with pretty much anything to do with off grid solar.

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.
