jnasty Posted September 9, 2020 Report Share Posted September 9, 2020 It's come time for me to switch to lithium with my upcoming build & I've had my eye on xs titan8 reserve.. but I've just come across jy power hp-40 which seems to offer substantially more power than XS for less$. There's not much comparison or material on either.. just seeing if anyone's also checked them both out Vehicle: 2002 Ford Escape Electrical: 275A Singer, 160ah XS/Yinlong lithium, 2,000farad XS Supercaps Head Unit: Apple iPad Hi-Res Passthrough Topping d10s Speakers: {ACTIVE} - (4) Arc Audio RS 6.0, (2) Arc Audio RS 4.0 & (2) Arc Audio RS 1.0 Sub Stage: (2) TC Sounds LMS Ultra 5400 18" Amplifiers: ARC Audio - (4)4200SE(comp modded, (2)4000SE Processing: Helix DSP Pro W/ Dash Mounted Director Link to comment Share on other sites More sharing options...
bmwking Posted September 9, 2020 Report Share Posted September 9, 2020 fyi you want the titan8 power, not reserve. Link to comment Share on other sites More sharing options...

I thought the reserve would work best with the quick discharge of the caps. Although my setup isn't super high wattage, the amps are 60% efficient... So my 5560rms is actually drawing 8900.

There's not much comparison or material on either.. just seeing if anyone's also checked them both out I was also looking at the JY power as well but I am only familiar with the 899$ pre-orders for their hp-40 variant not xp? I do know their HP packs utilize LiFePo4 chemistry versus XS Titan 8's using LTO. I am in a similar situation to your setup, I plan on running two DC 2ks at 1 ohm each, around a 60-70% efficiency at 1 ohm, along with cap banks and 240 Alt. Logically I think a daily would prefer a rsv bank compared to a bursty pwr bank but I look forward to seeing in build numbers comparing each 🤔 SMD Tool Map (2022): https://www.stevemeadedesigns.com/board/topic/220267-smd-tool-map-2022/ My Port Size Calculator (in progress): https://www.stevemeadedesigns.com/board/topic/217087-port-size-calculator-in-progress/ Common Port Walls for a Slot Port: https://www.stevemeadedesigns.com/board/topic/217076-common-port-walls-why-it-matters-to-your-box/?tab=comments#comment-3240313 Link to comment Share on other sites More sharing options...

For the $ the HP-40 looks like a great deal compared to XS pwr titans which are 10/20ah (per/reserve).

audiofanaticz Posted September 10, 2020 Report Share Posted September 10, 2020 You can't really compare one battery chemistry to another by the ah rating alone. Link to comment Share on other sites More sharing options...

For the $ the HP-40 looks like a great deal compared to XS pwr titans which are 10/20ah (per/reserve). From what I can see the JY offering has a lower c rating (2c?) than the Titans (10c+). That's why I went with Titan. I think the Titans are smaller as well.

Titans are definitely smaller & about half the weight too.. I'm not sure if I'm doing this correctly with this online calculator but it seems the titan will last only 6min with 100a of current & the JY 30min @ 80a.
