The ASOL 12.8V 100Ah LiFePO4 Deep Cycle Battery is a maintenance-free, drop-in replacement for 12V lead-acid batteries in RV, marine, solar and off-grid systems. Delivering 1280Wh of usable energy with a built-in smart BMS and a long 4000+ cycle service life, it provides reliable, lightweight power at roughly a third of the weight of an equivalent lead-acid battery.
🔋 12.8V 100Ah · 1280Wh of Usable LiFePO4 Energy
Unlike lead-acid, this LiFePO4 pack delivers nearly its full rated capacity and a flat voltage curve from full to empty — so your appliances run at stable power for longer.
- ✅ 100Ah / 1280Wh usable energy (vs ~50% usable on lead-acid)
- ✅ Flat discharge curve for stable device performance
- ✅ Zero maintenance — no watering, no equalising
🔄 True Drop-In Lead-Acid Replacement
Built to a standard 12V group footprint with the same terminals, the battery drops straight into your existing lead-acid bay — no rewiring or new hardware required.
- ✅ Same form factor & terminal layout as 12V lead-acid
- ✅ ~1/3 the weight for easier installation and better payload
- ✅ Compatible with most standard 14.6V lithium / AGM chargers
🛡️ Built-in Smart BMS Protection
An integrated Battery Management System continuously protects every cell, so the pack stays safe in demanding mobile and off-grid use.
- ✅ Over-charge & over-discharge protection
- ✅ Over-current & short-circuit protection
- ✅ Temperature monitoring with safe LiFePO4 chemistry (no thermal runaway)
♻️ 4000+ Cycle Deep-Cycle Life
Rated for 4000+ charge cycles — many times the life of lead-acid — for years of dependable daily cycling and a lower total cost of ownership.
🎯 Applications
- 🚚 RVs, motorhomes, campers & van conversions
- ⛵ Marine, trolling motors & boats
- ☀️ Solar energy storage & off-grid cabins
- 🔋 Backup power, mobility & light industrial equipment
