There are 2 parts to a lithium battery; the cells and the BMS.. so, how to choose when everybody makes the same claims?  Many online sellers use only the cheapest  cells with the lowest discharge rates ( 100Ah battery giving out only 100amps max ) and basic BMS's to keep costs down and assembled in china. Although these off-the-rack batteries work.. to a point... don't expect too much for too long.

The cells we use are higher than 1C, lower impedence ( .5mohm ), grade A only and with the highest lifecycles we can find for the chemistry. The biggest names have the highest overhead, thus charge more for their " brand" but still use the same 1C cells as all the others, calb, catl, eve...

BMS: does it have bluetooth ?, continuous & max discharge rates ?, balancing current rate ?  LVC ? over charge and over current protection ?

 

Boating benefits from lithium batteries;

 

- Bluetooth to monitor battery status

- can be discharged down to 90% vs 50% for lead acid

- level discharge curve

- drop in replacement for lead acid

- 2000 + cycle life

- recharge faster than lead

- no off-gassing like lead

- < 1% self discharge / month

- 1/6 the weight of lead and 2/3 the weight of comparable competitors lithium batteries.

- cheaper  to own over cycle life than lead                                                                                   Lithium Starting battery

- You can LIFT the darn thing without breaking your back!                                                        for Volvo Penta D3

... remember; price is what you pay , but value is what you get...

How much weight in batteries can you lose ?t me.

 

The answer is: up to 500 lbs depending on what batteries your running now. If its 8V golf cart batteries, then please, do your boat a favor and dump the lead! Your boat will thank you, then replace them with a Seaquest Lithium trolling or lithium outboard battery

at 1/4th the weight and twice the power, twice the runtime and a greater top speed. Get on plane quicker to get to that prized fishing spot before the other guy. There can only be one big catch of the day.. make sure its you with help from Seaquest battery.
