Most large vehicles such as lorries, HGV's and semi trailers use a 24volt system for starting the engine, which is made up of two 12volt batteries in series. These two batteries can easily get 'out of balance' which leads to one over-charging and the other under-charging. In both cases, the batteries end up with a very short life of only a couple of years.
For maximum life and trouble free operation, these two batteries need to be properly balanced. To ensure this happens, we have created the Vertex Bank Balancer which moves charge between the two batteries as requried to keep them exactly equal at all times - even when the engine is not running. It is seriously tough and waterproof so you can install outside next to the batteries. And just connect one wire to GND, one to the half-way point of the two batteries, and the third to +24V – that’s it!
Without Vertex technology, typical start battery life is around 2 years with both batteries having to be replaced as a matched pair. Adding a Sensiotech Bank Balancer can extend starter battery life up to 6 years, and with these large batteries costing between £100 and £200 each, this means a saving of up to £800 every 6 years! The Sensiotech 24V Bank Balancer can pay for itself within one set of batteries.
