Thread: SSB HVT 50D Vs SSB HVT 65D

Costly at $900 bucks but serious power. When my yellow top dies I’ll bite the bullet and try it. I expect there not far of a full size disco size start though on output specs this could drop in as a replacement start battery for the one there now.
This is the only one I’ve seen advertised and warranted as a straight drop in under bonnet Lithium. 2 year replacement.
They claim fully Ozzie battery.
concede a traxide sharing with decent AGM is more economically viable but for those who don’t really want to share there start battery for camp duties the full discharge of these batteries gives you serious useable power.
It has my attention anyway.

I have the space under the bonnet, and rather tempting solution.... But all other lithium makes dont rate under the bonnet. Am about to get two aux battery solution up to the same price of that 1 lithium you mentioned... Just dont have the charger compatible for a lithium.

Deep Cycle Systems,also have kits and run them under the bonnet.

Talk to anyone else in the industry,and they say no way.

Any cranking battery is the perfect deep cycle battery and any preference for not using it to assist the power an auxiliary battery is supplying while camped, is based on nothing more than myths and no real knowledge of how batteries work and are used.


But putting this MYTH aside, using something like an SSB HVT 50D, you will have 55Ah and not discharge the battery below 11.5v, even though the manufacturer states they can be cycled down to 10.8v.


The SSB batteries, like any lead acid battery, can be used with a conventional VSR type isolator, but lithiums can not.


Once the motor is turned off, you must separate a lithium battery from a lead acid battery but this can only be done with a solenoid.


Because the settled voltage of a lithium battery is way to high for a VSR type isolator, if used, the isolator will only turn off if and when the lithium battery get to a near flat state of charge.


Now there is also an additional problem/limitation when using either a conventional VSR isolator or a solenoid.


When a modern vehicle, not just Land Rovers, but any make with a SMART alternator, which is most vehicles ( Toyotas being one of the exceptions ) because the SMART alternator will lower the voltage when it detects a fully charged or near fully charged cranking battery, when trying to charge a lithium battery from the alternator, the voltage may drop so low that the vehicle actually runs off the power coming from the lithium battery.


This is the very reason it is far better to charge a lithium with a DC/DC device.


So before everybody goes buying lithiums, you need to do your homework and the math.

Super start no longer carry HVT-65D, sucks. They recommend CBC12V75AH.

FYI -


CBC Series Rated for Under Bonnet Use - Can also be used as a vehicle Starting battery or Dual Purpose Starting/Deep Cycle/Marine battery. Warranty covers under bonnet use

Would be fine.

Be careful of the bigger battery, going be the specs, I think you will find the battery will sit to close to the bonnet.

The terminals can be swapped for m8 to save on height. Can’t use the LHD battery clamp down bracket due to the shape of the battery, so I will make my own. Brake compartment cover can be used.

Goodchild stock a lot of things on shelf which is great, seems accomodating.

Your batteries are in 180° off
