14.8V 4400mAh 4S LiPo Battery 35C XT60
• Specifications: 140 × 42 × 31mm / 5.5 × 1.65 × 1.22in; 412g / 14.53oz; 4400mAh; 14.8V (4S LiPo); 35C continuous discharge; XT60 plug.
• Designed for Mid-to-Large Scale RC Aircraft: This 4S 4400mAh LiPo battery delivers sustained 35C discharge for mid-to-large fixed-wing planes (700mm–1200mm wingspan), 450-class RC helicopters, and medium gliders. The 35C rating handles takeoff, aggressive climb, and full-throttle maneuvers with stable voltage from launch to landing.
• Compatible Models: 4S fixed-wing RC planes, 450-size RC helicopters, EDF jets, and medium gliders with an XT60 battery bay. Check your model's manual for recommended battery dimensions before ordering.
⚠️ Before Ordering — Verify 2 Things:
• 1) Your aircraft's battery bay fits 140 × 42 × 31mm (including XT60 plug clearance).
• 2) The battery plug is XT60 (two-pin with center tab). If either doesn't match, this pack will not fit.
• Package: 2× PCEONAMP 4S 4400mAh 14.8V 35C LiPo battery (XT60 plug), 1× storage box, 1× user manual.
Frequently Asked Questions
Is this battery compatible with my RC plane or helicopter?
Yes, if your aircraft uses a 4S (14.8V) battery with an XT60 plug and the battery bay fits 140 × 42 × 31mm. Specifically designed for mid-to-large fixed-wing RC planes (700mm–1200mm wingspan), 450-class RC helicopters, EDF (ducted-fan) jets, and medium gliders. Verify voltage, bay dimensions, and plug type before ordering.
What does XT60 mean? Is it the same as XT30, Deans T, or IC3?
XT60 is a two-pin connector with a center tab, typically yellow. It is NOT interchangeable with XT30 (smaller), Deans T (T-shaped), IC3 (three-pin), 4mm Bullet, or any other plug type. Check your aircraft’s original plug or manual to confirm it is XT60 before ordering.
Can I charge this with a standard LiPo balance charger?
Yes. This is a genuine 4S LiPo battery. It charges via the JST-XH balance lead using a standard 4S LiPo balance charger. Recommended charge rate: 1C (4.4A) for daily use, up to 2C (8.8A) for quick turnaround. Always charge on a fireproof surface and never leave unattended.
How long does it take to fully charge?
At 1C (4.4A), approximately 60 minutes. At 2C (8.8A), approximately 30 minutes. Use a charger rated for 4S (up to 16.8V). Do not use a Li-ion USB charger or a LiPo charger set to fewer than 4 cells.
What does 35C discharge mean? Can I push it harder for short bursts?
35C means this pack safely sustains approximately 154A continuous (4400mAh × 35C). Most quality LiPo packs tolerate short 3–5 second bursts at 1.5–2× the C rating (up to ~230–310A) for aggressive takeoff or full-throttle pull-ups. For sustained high-current use (EDF jets, 450 heli at full throttle), we recommend staying at or below 35C to protect cycle life.
How many charge cycles can I expect?
Under normal use with proper practices (avoid deep discharge below 12.6V, store at 40–60% charge), expect up to 350 cycles before noticeable capacity fade. Avoid storing fully charged or fully drained for extended periods.
Can I use this battery for F3A aerobatic competition?
No. F3A aircraft typically use 5S (18.5V) batteries, often 2 packs in parallel. This is a 4S (14.8V) pack — the voltage is incompatible. For F3A, look for a 5S 4000–5000mAh 35C+ pack with a matching connector.
Can I use this in a 550 helicopter or larger aircraft?
Not recommended. The 35C rating (~154A continuous) may not be sufficient for sustained full-throttle use on 550+ helicopters or very large EDF jets. For those applications, consider our 5S 5000mAh 35C or 6S 5500mAh 45C packs which offer higher sustained current.
What comes in the box?
2× 4S 4400mAh 14.8V 35C LiPo batteries (XT60 plug, JST-XH balance lead), 1× LiPo storage box, 1× user manual.
