Winter battery madness is here! 15% off for all systems purchased before the end of Black Friday!

LiFePo4 from epoch allows one group 31 sized battery to replace three 8d batteries in overall capacity!

Coupled with victron charging systems and the swap is simple.

A lot of people ask what they require to use modern battery systems with 6x higher capacity and up to 10x longer lifespan. You can use up to half a rated capacity of an AGM battery, you can use the entire rated capacity of an Epoch!

1. The start bank requires an external regulated alternator, either
balmar or wakespeed.

2. A charging system that works with LiFe Po4, Victron is the king for simplicity and cost but most systems installed within the last five years support lithium battery types.

3. Qualified installations, thats us!

Here is the greatness of Epoch! The price works.

The cost, before our sale discount for a 12v 300ah battery is $1,199, after sale $1,019!

Three comparable 8d AGM batteries $2,737!

Same useable capacity. Proven reliability.

Less expensive, longer lasting, higher capacity.
